Catapult Impact On Society
Another interesting effect of the catapult was the importance of specialized people. Before the
catapult was invented, soldiers only had to be trained in fighting. After the invention however,
mathematical and engineering skills became important to be able to build and operate a catapult.
The catapult moved the social status of an engineer from "dirty, ugly, and lame," to an important
member of society who was in high demand (Foley and Soedel 8). The creation of the engineer also
changed the structure of labor and how innoventions were developed. Catapults represent some of
the first examples of modern engineering. Dionysius, ruler of Syracuse, was the first to create these
devices, and created them by using modern engineering practices. These included using large
specialized teams, splitting work to be done into feasible sizes, and giving financial compensation
(1). All this change in status and importance of the engineer brought down likeness in Greek society.
Because warfare was based around only soldiers fighting before the invention of the catapult, soldier
conformity was important. One ... Show more content on Helpwriting.net ...
For example, Wheeler writes, "Strabo's quotation of the inscription does not mention the Lelantine
War, but the context of the inscription in Strabo is the Lelantine War. So Strabo (or his source) made
this connection, whether or not the war was the inscription's original context" (160). This shows
there is a change the treaty does not even have any connection to the war being discussed. Also,
Wheeler says, "Polybius' account of the alleged treaty in comparison to Strabo's is vague and
practically useless, except for its role in leading scholars to posit a common source for the two
accounts" (161). This unveils another big problem with the literary evidence. If there is only one

The History and Importance of the Trebuchet
"Any sufficiently advanced technology is indistinguishable from magic." A. C. Clarke (Clarke).
Throughout history, people have relied on technology to aid them. Technology has played an
important role throughout time as a tool that has allowed people to achieve accomplishments never
before possible. Technology has been crucial to survival as it has been used in warfare. Technology
was used for both offensive and defense systems during times of siege, and could determine the fate
of entire empires. Siege engines were some of the most important technological advancements of
their time and could drastically sway outcomes of battles. Of the siege engines, the trebuchet played
a very influential role in history for nearly two thousand ... Show more content on Helpwriting.net ...
Compared to the trebuchet, the designs of other siege weapons were lacking in many respects. The
most important of these other siege engines included the Greek ballista, the catapult, and variations
on the catapult design, such as the Roman onager and mangonel. The ballista's design was very
similar to an extremely large crossbow with a guide chute to keep the projectile on path. A large
ballista could launch an eight pound stone over 450 yards. It took two men to operate a ballista
(Hamper). A standard catapult used the inconsistent strength and weight of men as a source of
power. Groups of men had to work to pull down the catapult bar in order to launch the objects. Such
catapults could typically throw as much as a fifty pound rock. An onager was type of a catapult with
a short arm that would be launched forward by many twisted sinews. Both the onager and the
ballista were limited in accuracy and range, because the tightly twisted sinews and ropes continually
wore out and needed to be replaced. Likewise, the standard catapult lacked accuracy because of the
inconsistent strength and weight of the men who fired it. While all of these siege machines were
useful, none of them had the range, or were as powerful, accurate, and widely used as the trebuchet
(Gurstelle 18–22). The trebuchet was by far the most powerful, accurate, and reliable of all siege
weapons

Throughout history, especially during the Middle Ages, numerous weapons and tools were invented
in order to aid in the victory of battles. Such examples would include the catapult, a device in which
collected tension is suddenly released to hurl an object some distance, in particular. Catapults are
actually very much related to physics and the world of mathematics, due to its function, and the

As the parts are supported, there is an elastic rubber band that stretches from one standing stick to
the other, which is where our spoon (the scooper/releaser) is held down by the base and pulled back
to function like that of a catapult. A catapult operates using gravity that pulls downward, and an
object that can lob through the air with enough force that can defy gravity, is thrown in an upward
and forward direction. Then it'll launch to form a special curve that is formed like an arch, which is
called a parabola. It will then eventually land downward and forward. As a group, we've observed
multiple parabolas that was made from our catapult and measured the distance and height of seven
total attempts. From there, we chose the three best and and most consistent, which led to finding the
three main points in our table and plotted on our graph––(0,5) which is our y–intercept since it was
launched 5 inches off the ground, next it was averaged to (103.75, 63.3) which is the vertex showing
the maximum point of our parabola reached by our catapult. It was found by the average of our three
best points and the farthest distance was divided in half to find the x–value as the y–value

Catapults were one of the earliest forms of large weapons, in which projectiles were shot. "The
general definition is that a catapult is a machine that stores energy then quickly releases this energy
to fire a projectile," said Kalif (Kalif, 2007). Catapults are basically a spring compressed together
ready to release and explode into action. Catapults have been used in battle for many, many years
shooting objects from rocks to fire balls. There are three main types of catapults including: the
ballista, the mangonel or onager, and the trebuchet. These three catapult were very useful and

"The trebuchet is a counter weight siege engine" (Alchin, 2015c). The trebuchet was invited around

using a frame and an arm with a rope or a counter weight attached to one end of the arm. The other
end of the arm had a a bucket to place the projectile. There are two types of trebuchets, they differ in
the way they are shot. The first trebuchet was shot by people pulling on one end of the arm. The
other was shot by a counter weight on the opposite end of the arm from the projectile. Both used
gravity to bring the arm up and project the object into the air in the direction of the target. The
trebuchet could not shoot as far as the others but was pretty accurate (Vick, 2015

Those who mounted the belly–bow would be launching a type of object with their belly on the
launcher and that is where reference belly–bow came to be. The belly–bow consisted of a syrinx, a
pipe and diostra, then lastly a slider. It was told that the gastraphetes could launch 40 pounds 200–
300 feet in the air. With this new form of technology, Grecian engineers were able to evolve the
gastraphetes into what we know as a catapult. The Grecians used a ballista creation of a catapult to
launch objects into the desired target. To power the catapult, Grecians would use horse hair and an
ox tendon. This helped create tension so that they were able to launch objects farther. In dire times
of need, the women would cut their own hair to replace the horse hair. They also implemented
wheels within their catapults to roll them to their desired spot. Often, the catapults weighed a few
hundred pounds and would be nearly impossible for it to be carried multiple times a day. The wheels
also made it easier during times of war. The farther the enemy was the closer the troops could have

The ABMAMACAW Catapult Catapults were first made to hurdle cats (on a more serious note).
There are many different types of catapults, such as the mangonel catapult. The mangonel catapult
which our catapult is based on was created in 400 B.C. by the Romans. The mangonel was created
like the Greek ballista but was smaller and mobile. Our catapult was based on some aspects of the
mangonel. In the following I will talk about the process and materials used to make it and the
science of the catapult.
Some of the materials we used are:
Wood– for the structure of the catapult

As the ball is being pulled down by the pull of gravity of the earth the potential energy is now
converted into kinetic energy. It is not really converted because even though at its peak it had
potential energy it was still in motion meaning it still had kinetic energy. The ball is now falling.
When the ball has no more vertical momentum it is pulled down to the ground by gravity. When the
ball hits the ground some of the kinetic energy is converted into sound energy then back to kinetic
energy. The ball is now bouncing. When the ball is at its peak it has potential and kinetic energy. The
ball keeps bouncing and transforming energy until it finally comes to a stop.
Our Catapult is also a first class lever. As you can see in this illustration, the ball is the load, the
fulcrum is where the pipe is connected to the center block of wood and the input force is the bungee
cords. A first class lever has the fulcrum between the input and the output force. I said earlier the
bungee cords have potential energy. When the pipe is released the force of the bungee cords pulls
the bottom of the pipe towards the person holding the pipe in this case Maria). This is a fist class
because when you apply a force to one side (bungee cords) the other force exerts that force but in
the opposite direction (ball being shot).
As we worked through our construction and testing phase, we found our original design of a 5' by 7'

The catapult is an ancient artillery device that used the elastic power of twisted fibers to hurl
projectiles. The invention of twisted fiber artillery and siege engines has been credited to the
Greeks,from 300 BC. These catapults used a lot of human hair. tons of human hair is how much was
needed for these machines.
The Romans made improvements to the catapult's basic design and perfected its use in battle. The
simplest early catapult used a thick bundle of human hair, with one wooden beam inserted through
it. Geared winches were used to twist the hair without letting it unwind.
In medieval Europe, a catapult that operated like a crossbow came into usage. It had two short arms
that moved horizontally instead of one large beam that moved

In this experiment, no calculations were needed to be completed. However, there were sources of
errors and variables that affected the design process of the catapult. Such as, a failure in picking a
design, miscommunication, no retest, and an emotion of unpreparedness. To recall, there was not a
collective collaboration on what design was going to be built. Instead, a variety of different designs
were being built at the same time. Although having options is a positive outcome, it caused
arguments between the members because everybody was pointing out the negative in their team
members design. As a result, miscommunication and a lack of patience spreaded throughout the

The physics behind a catapult can be a complex topic to grasp. But, when broken down, looking
individually at their historical uses, design types, and related physics concepts, it's surprisingly
simple to form an opinion on which catapult design is most effective and why. These categories,
when combined, define the uses, functionality, and effectiveness of the historical (and modern day)
catapult. Catapults were originally developed in 399 B.C, and had derived their "shooting" power
from springs, twisted bundles of cords, or heavier weighted cords. When the twisted ropes on these
catapults were released, a stone weighing around 50 pounds could be launched the length of four
football fields, though some of the largest catapults could throw stones up to 600 pounds, and some
of the smaller models were used to launch flaming arrows at foes (Jason Richie, Designing the Tools

The ballista is also a very viable option, but I truly believe the trebuchet is the way to go, and let me
explain why. First, the transfer of energy that occurs when the weight is dropped, should allow the
projectile to launch quickly and have significantly more force, which is important when hitting the
intended target. Second, a trebuchet was originally used more than the basic catapult, and far
preferred, due to its greater range capabilities and improved accuracy. The mechanical advantage of
dropping the counterweight to lift the beam, allows the payload to achieve a higher velocity, which
creates a faster more efficient catapult. There are many other types of catapults that use different
physics methods to achieve high speed and a strong force, but between the more complicated
structures and the varied intentions for uses when being built, each other model performs tasks
differently. Therefore, I believe the best catapult option is the classic

I am researching this because I am interested in medieval and roman weaponry and how it works so
it was a simple choice to make and test different weapons from those eras. I am finding out which
shoots the furthest the crossbow, the catapult, or the slingshot and if I do not know how they work, I
cannot compare them to each other so I decided to research this.
My hypothesis is that the catapult will shoot the furthest and I think that I am right do to previous
research by professionals. But in other cases the catapult is made to full size but in this case it is
made to a scale factor of 25% of its original size so that might affect the result because in the larger
version there is more force on the launcher and in the crossbow there isn't as much tension build up.

Pulling back on the string creates elastic energy and when the string is released the elastic energy

The story of the young shepherd boy named David, who defeated the warrior giant Goliath, with
nothing more than his slingshot has become a symbol of how man, or in this case a boy, can achieve
anything with faith and a great deal of will power. Here we compare two statues of the same boy,
each telling a different part of David's story. One depicts the boy moments after the battle and the
other depicts David during pivotal moment of his life. Although both statutes have many features in
common, there are many differences that would suggest Donatello's David was not only meant to be
the victorious David but also meant to be more than just a narrative piece like Bernini's David.

and confidently gazing down at the viewer. David leans on the sword in his right hand and holds a
stone in his left. His lax composure and the slight smile on his face would imply that the battle is
done. Clean shaven and with long, luscious hair, it is assumed that David is rather young, which
makes his victory over the giant even more remarkable. The viewer gets a sense of the how large
Goliath the giant truly was when they glance down at the bottom of the composition and realize, the
giants head is nearly twice the size of David's foot.

The physics concepts associated with them are projectile motion, energy, momentum, forces ,
speeds, and distances. The kinds of catapults all use the same theme of accumulated tension, but
acquire that tension in their own way, their own design. The Mangonel catapult for instance, is what
most of us think of as the traditional catapult. A large wooden device with four wheels and a spoon
that launches fireballs. The Mangonel stores energy much like a spring would, therefore, we use the
equation PEspring = 1/2kx^2. The tension in the ropes and arms of the catapult when pulling on its
long arm stores potential energy which is transformed into kinetic energy when fired upon. (Melvin,
Mangonel – "Physics of Catapults") The speed and distance of the projectile depended on how much
force the catapult applied to the projectile, and the momentum depended on the mass and the
velocity of the projectile (dead diseased cow, or flaming

Catapults were ballistic devices. It was invented by a man named "Dionysius the Elder" and created
it around 400 BCE. Since then it was a key weapon in warfare. The way it works is that a piece of
wood called the arm was connected to a cup shaped bowl but another name for it was a bucket. The
bucket was meant for holding the object you wanted to launch. The objects people decided to launch
whatever it was it was called the payload. The arm connected to the bucket is laid flat down and
springs vertically up once the user pulls a lever to launch or does it manually it will make the object
launch in its desired direction. Sometimes there would be wheels at the bottom so it will be easy to
move if the target is moving. A catapult was used to fire ... Show more content on Helpwriting.net ...
In the middle ages it was commonly used. They were used to breach walls and garbage would be
catapulted over the walls. During the World War I they would use catapults during the "trench of

getting seen. In the current time they are often used for school fairs or projects as a grade in school.
The trebuchet was a similar model to the catapult. The trebuchet was used in medieval warfare
similar to the catapult and launched large stones or missiles. Other similar designs such as the
mangonel terrible accuracy and was also used in medieval sieges. There were many different models
for the catapult itself and all of them work very efficiently. In the experiment it will test which
design of catapult will be effective at launching a ping pong ball the farthest distance with the same
exact force every try. Newton's first law applies to the catapult. When the arm of the catapult springs
up to launch, it has a change in motion which makes the projectile move. Inertia also applies to a

A catapult is a device used to launch an object in a specific direction. Greeks, Romans, and the
Chinese used various types of catapults. They were originally created to increase the power and
range of a crossbow. Catapults were made with wood, rope, buckets and any other objects they
could find that would help launch objects. They were made in many different sizes, some were big
others were small. The biggest catapult was the Trebuchet. It could launch stones in between 200
and 300 pound stones 1,000 feet.

The men would bring down the shorter end of the long beam or arm, causing the longer end of the
arm to flip up, causing the basket to loose it's projectile towards the intended target. Some of these
siege weapons were held by men and cause some difficulty in battle.Gravity powered catapults
simply used gravity to hurl the projectile. At its most basic understanding, a gravity catapult is
simply a lever that uses centrifugal force to its advantage. Think of it as a modified seesaw. When
two people are on the seesaw and both are of close weight, the seesaw balances itself. If another
person came up and jumped on one end of the seesaw with one of the people, the single person on
the opposite end is likely to become airborne. Like the seesaw, a gravity powered catapult is also
pivoted in the middle. A counter–weight was built onto one end of the catapult and a basket or sling
on the other. The projectile end was pulled down forcing the counterweighted end to

My reason why making this simple catapult was to show how to make a simple machine without
pulleys and lever and things like them also I wanted to make a simple machine that can move things
to one place to another. You need information because you need to know what they are how the
actual catapult work and how the miniature catapults are alike and how the parts are alike and
different and what parts do what. Scientific concepts or principles the catapult uses are angles,
attitude, power, distance, and weight. I have never researched this in the past but

The catapult is a machine that launches an object into the air by using sudden tension. When people
launched catapults, the object that was launched forms a parabola to hit the target otherwise known
as a projectile. There are forces that act upon the object such as gravity and initial velocity. To
calculate where the object lands, people use the vertex form and the quadratic formula. The vertex
form is y = a(x – h)2 + k in which a is equal to the slope of the parabola, h is equal to half of the x
value and k is equal to the y value of the maximum point. Also, people can find the farthest distance
where an object could land by using the quadratic formula. Therefore, vertex form and quadratic
formula are used to determine the path of the catapult's

Do you know how a catapult works? It uses a weight or tension.
According to research, you need a projectile lighter than the weight to launch the projectile. If the
weight is too light it won't launch the projectile. To see if if it's heavy enough, you can weigh it.
What is a catapult you might ask... Well, a catapult launches a projectile from one place to another,
from the weight/tension of the rubber band or weight of metal that's going to make the object get
pulled from the weight of the object and launch it forward through the air. The best way to make it
launch is too get a small, (depending on the size of your catapult) and get a weight of some kind,
make sure it's heavy enough to make the projectile go through the air and far. If the projectile is to
heavy for it to be thrown then it will just drop it on the ground or not move at all. If that happens
then you should make the projectile lighter or make the weight heavier so you can actually make it
go further. If you make a small one like mine you probably would get around 5–15 feet (depending
on the size of the catapult). "The decisions you make each day can actually catapult you to that next

Well, a catapult was used back in the 14 centuries to break down walls of castles so the invaders can
go in the castle and read them. It was much easier to do that than to get a ladder and climb it up and

take down targets from long ways, the ammo that they shot was mostly a couple of big stones. This
was really helpful back then because all you need is to get wood, stones, and rope. This is why it

First, we built catapults out of popsicle sticks and rubber bands, this process was hard and took a
while. We had to wrap the rubber bands around each popsicle stick to connect them, then we had to
hot glue a cap to the top to hold the marshmallow that we would launch. Next, when the catapult
was finally built we were ready to start the tests. We first calculated the distance the marshmallow
would go when we launched it using one rubber band, then two, and then three. I noticed that with
one rubber band the marshmallow didn't go very far, then with two rubber bands it seemed to go
three times as far as one. Lastly, we tested the accuracy of our catapult.

Thesis About Catapults
Would you like to learn about ping pong balls and catapults? I got my information from science
buddies on how to make my catapult. I also got information from buzzle. My thesis is if the catapult
is at a 30 degree angle, then the ping pong ball will go farther the further the arm is pulled back.
How most catapults work. It has force and strength. It has an arm that hurls an object though the air.
It needs other parts to work. Big catapults have a rope and spring. Little catapults usually have
rubber bands. Catapults are strong and need parts to make it work.
Ping pong balls and what they are. They're light weight. They have nothing in there but concealed
air. They're a little hard. They're made of a hard plastic which allow them to bounce

Medieval Catapult Lier
The Medieval Catapult Lier versus the Zombie With the threat of zombies quickly approaching, a
spring catapult needed to be built to protect Rome High School and the rest of the world from the
upcoming apocalypse. That catapult is the Medieval Catapult Lier (aka MCL) which can be
analyzed from the picture at the bottom of this essay. The MCL went through many adjustments
such as in arm length, nail strength and tension before it could launch a tennis ball at a significant
distance. Nevertheless, it was all worth it and could not have been done without the crucial subject
of physics and the study of motion and energy. In this "very likely" situation of defeating zombies

Then, one would measure how far the bungee cord was stretched because of the weight which
turned out to be 1.0668 meters. So, when substituted into the equation F bungee cord = – kx, the
equation would look like 8.896 Newtons = (k) * 1.0668 meters and then solve for k by diving to get
that the bungee cord constant, k, is equal to 8.34 (Newtons/meter). However, solving for k does not
provide the elastic potential energy but contributes to the answer. All there is left to do know is to
substitute values into E=12 kx2. The only difference here would be that x in this case would be 1.6
meters as that is how far the bungee cord stretches when the moment arm is pulled all the way back
and everything is hooked together. The value of k can be transferred from what was solved for with
the last equation. When all values are substituted, the equation would become E=12 (8.34 N/m)(1.6
m)2. Therefore, the elastic potential energy, E, is equal to 10.6752

Catapults: the revolutionary weapon that has been used to win battles for years. They have a long
history, varieties of different types, and relevance to modern–day scientific principles. Even though
they are mostly used as toys in today's time, they have still kept their relevance and overall
individuality in the scientific and war–time categories. Before continuing, it should necessarily be
defined what a catapult even is. Scientifically, they are a machine that stores energy in order to
release a projectile, but they have a long history attached to them, as well. Catapults were originally
the outcome of creating new crossbows–which then transformed into something so different they
described it differently than any old crossbow. The ... Show more content on Helpwriting.net ...
When these forces are exerted on either an object in motion or at rest, these states of motion can
change. For example, when launching a projectile from the catapult, the object was initially at rest
until the force exerted by the catapult arm launches the catapult into the air. While in the air, the
projectile experiences another force (gravity) which causes its path of motion to change. This path
of motion is called projectile motion, or the combination of horizontal and vertical motion that
happens on any thrown object. Without the discovery of newton's first law, projectile motion would
have never been discovered, and accuracy would greatly decrease. This is mainly because of this
combination of horizontal and vertical motion, which changes where the object will hit the target, as
well as the accuracy of the object itself. As an example, take a bow and arrow. If you were to aim
exactly for the bullseye on a target, you would not be able to hit it due to projectile motion, which
causes the arrow to curve down at an angle before it even reaches the target. This is the same with a
catapult projectile, also having this downward curve before it becomes at rest by either hitting the
ground or the

Physics Behind Catapults
Have you ever wondered how a catapult works? We had to ask just that question when we were
assigned a project. Where we had to create a functional catapult and graph the arc of the object shot
from the catapult we created. In this essay I will discuss the history and mathematical concepts
behind catapults. I will also include some fun facts.
There are many mathematical concepts behind a catapult. One big mathematical concept behind a
catapult is a parabola. A parabola is defined as "a symmetrical open plane curve formed by the
intersection of a cone with a plane parallel to its side. The path of a projectile under the influence of
gravity ideally follows a curve of this shape." A parabola is the shape of the arc made by the object
launched. Sense the arc is a parabola not only will the curve of the object going up be same as it
going down but, the arc can also be graphed. ... Show more content on Helpwriting.net ...
It depends on the angle it is shot at because if the angle to low or high it will have a very short
range. It depends on force because the more force applied to shoot it the farther it will go and the
less force you apply the less range you will have. Another thing that will affect the range of our
catapult is the tightness of the rubber bands. If they are to tight won't allow the catapult to be pulled
back and spring forward. If the rubber bands are too loose they won't hold it together and the
catapult won't be able to spring back like it's supposed to. The angle also plays a crucial role in the
range of a catapult. If the catapult is at to high of an angle it will shoot directly at the ground. If it is
at to low of an angle it will shoot directly up into to the air. Both things will cause a drastic decrease
in

Catapult Project Essay
This catapult project exemplifies and strengthened my current knowledge of parabolas that we have
learned during class. Using our skills, my group – Katrina, Brandon, Michelle, and I – created an
interesting catapult which would thrust a ping pong ball across creating an upside down "U" shape,
also known as a parabola. During our time as a group, we learned to create our own equation, create
a graph and table, but also learn from our mistakes by trying to make the ping pong's "journey"
consistent. Not only this, but we worked together as a team to get this task done.
Before even beginning to measure the ping pong ball's "journey", we had to create our own catapult.
Using materials provided by Ms. Csigi, such as popsicle sticks, hot glue, rubber bands, and a spoon,
we created the our own, unique catapult. First off, we created a square with four popsicle
overlapping each other. Then we created another square and connected the two by the edge, with
one side upwards. Then we got a spoon and glued it on another popsicle stick. Because the spoon
needed to be at an angle, we hot glued the bottom facing the bottom of the square. We connected
rubber bands to the spoon so that once we pull the spoon to ground zero, the ... Show more content

One of my group members were confused as to why ax^2 is negative, but that is because the ping
pong ball has to come down at a certain point. With this in mind, our group had to start at ground
zero since we can't start at a negative point. Or graph wouldn't make sense because the ping pong
ball cannot go down into the ground. Moving on, we actually found our standard form equation
(using the calculator) before our vertex form so we actually used this to our advantage. Instead of
doing all the unneeded work, we plugged in our vertex into the formula a(x–h)^2+k. So this way,
our vertex form equation would come out to be

Churchill And Operation Catapult
Put differently, Churchill tried diplomacy first with France and then indirectly through the U.S. Both
strategies serve as indications of Churchill's push to get the result he wanted. Nevertheless, the lack
of success with diplomatic efforts did not deter Churchill. It only drove him to devise a more
forceful, violent tactic: Operation Catapult. The conditions of Operation Catapult demonstrate that
Churchill carried out the attack at Mers–el–Kébir because he assumed Germany had plans to take
the French Fleet. All of the options included in the ultimatum that Britain gave France, including the
threat to use force, centered on keeping the French Fleet away from Germany. To demonstrate, one
of the conditions demanded that France permit the fleet

Catapult Physics
Catapults in modern–day don't exactly have the same job as they had back in the middle ages but
they still can used in combat. They're used on aircraft carriers to propel aircrafts in the air and also
are used on submarines and boats to launch differing items at their opponent . Some important
mathematical concepts that are used when building/designing a catapult is projectile motion,
accuracy vs. precision, and the use of the quadratic equation. Newton's laws work here as the first
law states an object at rest stays at rest unless acted on by an outside force while the second law
deals with Force = mass times acceleration, showing that having a larger mass and acceleration will
make the force applied to the projectile larger The materials ... Show more content on

Our tension giving material (bungee cords) were stretched from the front of our catapult to the arm,
over the bar that allows for a proper launch angle. The potential energy stored in the bungee cords is
at a maximum when the arm is pulled all the way to its farthest angle away from the launching bar.
When released, the bungee cords sling the arm forward as it rotates on a dowel. The arm hits the
launching bar, causing all the energy transferred from the chords to the arm to be transferred into the
golf ball. The golf ball is then hurled forward, and can reach a distance of about 17

Catapult And The Shooter
First in the design process was developing the concept solutions. The Catapult and the Side Catapult
(II & III in Fig. 1) were a classic design that had potential to be modified with a string pull trigger.
The Spinner and the Shooter (I & IV in Fig.1) resembled the design of toys that shoot a foam disc
similar the competition projectile. Our Datum for the decision matrix (VI in Fig.1) is a ramp with a
spring–loaded striker to propel the disc. The Pin model is a hybrid of the Shooter and the Datum (V
in Fig.1) by utilizing the ramp from the Datum and the rubber band propulsion from the Shooter.
The Decision Matrix is made up of eight criteria for comparison, to analyze the five concept
solutions based on the datum. Accuracy and price were weighted

Catapults used to be a major part of war back in around 400 bc–885 Ad before they became useless
but they were important because they could launch just about anything as far as it needed to go.
Certain situations such as launching boulders over castle walls or hand grenades into an enemy's
trench are all great uses that the catapult provides. When building a catapult it is a very precise task
involving lots of time to make. The design is very important because it's based off how heavy the
objects will be that it launches and how far they should go.
Catapults were a huge part of war up until around 885 Ad when they were replaced by small mortars
and rockets. However there are many examples of modern day catapults such as on an aircraft

"A ballista is an ancient military siege engine in the form of a crossbow. Typically it was used to
hurl large bolts, and had better accuracy than a catapult at the expense of reduced range." (What is a
ballista) A trebuchet uses man power to fire. "A trebuchet [nb 1] (French trébuchet) is a type of siege
engine most frequently used in the Middle Ages. It is sometimes called a counterweight trebuchet or
counterpoise trebuchet, to distinguish it from an earlier weapon called the traction trebuchet, where
men pulling ropes provided the power." (What is a trebuchet wiki) Finally there is the mangonel
catapult which first large objects at castle walls. A mangonel[1][2][3] was a type of catapult or siege
engine used in the medieval period to throw projectiles at a castle's walls. A mangonel had poorer
accuracy than a trebuchet (which was introduced later, shortly before the discovery and widespread
usage of gunpowder). The mangonel threw projectiles on a lower trajectory and at a higher velocity
than the trebuchet, with the intention of destroying walls, rather than hurling projectiles over them.
It was more suited to field battles.Mangonel is derived from the Greek mágganon, meaning "engine
of war", but mangonel may also be indirectly referring to the mangon, a French hard stone found in
the south of France. It may have been a name for counterweight artillery (trebuchets), possibly

Physics of Catapults Essay
The ballista, or "shield piercer," was first developed by the Greeks using the same principles as a
bow and arrow. Its primary use was to, as the name suggests, pierce enemy shields, since normal
bows lacked the power to do so. Early versions of the ballista include the gastrophetes, which is
nothing more than an enlarged bow that can be braced against the users body.

Using this relationship assumes that the force constant is constant, or that moving the arms back 2
meters gives twice the force that moving them back 1 meter would do, which is most likely not
correct, but close enough for a general assumption of the force to be made. When the force is
applied, the projectile is accelerated to the end of the ballista, at which point it released with a
velocity v and an angle q from the horizontal. The velocity can be found using the kinematic
equation v2=2ax, where a is the acceleration and x is the length of the ballista that the projectile is
accelerated upon. Since F=ma and F in this case is –kd, the equation can be simplified into v2=2–
kdx/m. After it is released, the projectile obeys the laws of projectile motion, disregarding air
resistance. Therefore, the range of the ballista can be given by the equation
R=v2sin2q/g,
where g is the accleration due to gravity.
Mangonel History
The Romans, finding the ballista difficult to construct, simplified the design and created the onager.
It had one arm instead of two, and is what is most commonly identified as a catapult today.

During the Dark Ages, the French were able to re–invent the onager, and they called it the

Catapults In The Film, The Kingdom Of Heaven
The Kingdom of Heaven is a film about the Second Crusades, it is based on history. The plot of the
movie is the Christians and Muslims fighting over Jerusalem. The movie all started with Balian's
wife committing suicide. Balian bared the crown for Ibelin, after his father, that he only knew for a
short time, passed away. After the war lasted 10 years, the Christians surrender and gave Jerusalem
to the Muslims. Of course Hollywood would take it to the extreme and not make it modern day. The
only reason they do not make it modern day is so that it catches your eye, and you buy the movie so

What Is The History Of Catapults
History of Catapults Catapults are war weapons that were invented in the hopes of increasing the
range and power of a crossbow. The first idea was the "Ballista," which was a mechanical crossbow
that actually performed like the Greeks and Romans wanted it to. Further into history, in the year of
1216, catapults that we perceive them now were being used. Named the mangonel, they were
massive weapons of destruction. England used a different type like the "Mangonel" which was the
primary catapult of this age, Throughout the Middle Ages, catapults were being used much more
than before. The castles of this age had to significantly increase the size and height of their walls.
The reason for this was due to enemies using the catapults, launching piles ... Show more content on

Each one had a different purpose. The mangonel is the type of catapult that most people envision
when they hear the word catapult. Iit consists of a bucket and an arm with a rope attached to the end.
The rope caused tension while pulling the arm back, then the bucket would be loaded. After it is
loaded the rope is released, the arm retracts into a 90͒ degree angle launching the items inside. The
trebuchet catapult "hurls" stones or other projectiles into castle's walls, destroying them quickly. It
mainly consists of a long arm that is balanced on the fulcrum that was far from the center. There is a
rope that attached to the long arm, until the counterbalance was high into the air. Math to find the
Parabola of a Catapult To find the "parabola" of the equation you will need to first test out your
catapult. You need to find out the vertex and the distance it traveled, which are the two variables
needed. You will be using the standard form equation, Ax^2+Bx+C. X will be determined by the
time that the item (Ping pong ball) is in the air. Another formula that can be used is Y= a(x–h)2+k,
even though we have not learned this what this formula is or how it's used. It is called vertex

Catapult Experiment
My hypothesis was if I change the materials of the arm, then the pom pom will go father because
popsicle sticks are too straight, and there are not enough bends. I accept my hypothesis because of
the data from my experiment. This experiment showed that when I changed the arm of the catapult,
the distance that the pom–pom traveled was farther. In the control catapult, the pom–pom traveled
an average of 10.78 cm and the range of the data was 24 cm. The first piece of evidence from my
data that proves my claim is the averages. In the control, the average was 10.78 cm. In my catapult,
the average was 87.6 cm. My catapult's distance was better by 76.82 cm. The second piece of
evidence from my data that proves my claim, is our graph.
