At the end of the lesson, the class
will be able to identify the different
         simple machines.

Simple Machines
Considered to be building blocks of machines
It helps the people make their work easier
The 1st machines are often called “the 6 simple
machines”

            LET'S FIND OUT WHAT THESE
                  MACHINES ARE! :-)




     Back                                 Next
The 6 SIMPLE MACHINES:
click the machine you want to know :-)
Lever            Wheel & Axle   Screw




Inclined Plane   Pulley         Wedge




     Back                               Next
Lever
                           Resistance force /
                                   load         Effort force
constructed from a
  beam attached to
  ground by a hinge, or
  fulcrum
The fulcrum balances 2
 forces: an effort
 force and a
 resistance force, or
 load
                          Hinge/
    Back                                        Next
                      Fulcrum
These are some other examples of
       Lever machines :-)




  Back         HOME           Next
Wheel And Axle
A wheel with a rod,
 called an axle,
 through its center lifts
 or moves loads.
They're everywhere! A
  large circle (wheel)
  connected to a smaller
  circle (axle) links
  distance traveled and
  power needed in an
  incredibly useful way
     Back                      Next
These are some other examples of
  Wheel and Axle machines :-)




  Back         HOME          Next
Inclined Plane
A slanting surface
 connecting a lower
 level to a higher level.




     Back                       Next
These are some other examples of
        Inclined Plane :-)




  Back         HOME        Next
Pulley
A simple machine that
 uses grooved wheels
 and a rope to raise,
 lower or move a load.
Each section of string
 supporting the
 movable pulley
 system decreases the
 force needed to move
 the load
    Back                    Next
These are some other examples of
       Pulley machines :-)




  Back           HOME        Next
Wedge
An object with at least
 one slanting side
 ending in a sharp
 edge, which cuts
 material apart.




     Back                   Next
These are some other examples of
            Wedge:-)




  Back          HOME         Next
Screw
An inclined plane
 wrapped around a
 pole which holds
 things together or lifts
 materials.




     Back                    Next
These are some other examples of
            Screw :-)




  Back         HOME        EXERCISE! :)
Now, are you familiar with the simple
       machines you've seen?
Let's test how you remember them.
 We will have some few exercises!
 Click the “Start” button if you are
         ready. Let's go! :-)

What am I?
You can usually find me during flag ceremonies, I
     help the flag reach the top of the pole.
  Lever          Wheel and Axle Wedge




  Pulley         Inclined Plane   Screw


      Back                            Next question
OOPS! THAT'S NOT ME.
 YOU CAN TRY AGAIN




        Try Again
CORRECT! :)
I am a pulley and you can usually find me on
top of the flag pole. It is easier for me to pull
 down and push up because of the movable
          rope that supports me :-)

        Try Again
CORRECT! :)

I am a inclined plane and you can always use
me as a guide to transfer heavy things inside a
                     truck

 cut materials apart because I usually have
   slanting side ending in a sharp edge :-)

  Pulley          Inclined Plane   Screw


       Back                            Next question
CORRECT! :)
 I am a hinge. A hinge is a kind of screw that
you can see between the side of the door and
 the wall attaching it. It is the one that makes
     the door open properly :-) Like this:

   I am a wheel and an axle. A bike is an
excellent example of it, because of the wheel
that makes it to move and a screw to secure
                    it :-)

I am an inclined plane and sometimes I can
   also be a slide in playgrounds and fun
                  parks :-)

CONGRATULATIONS! You have successfully
    identified the different kinds of simple
 machines. You might think of it as “simple”
   yet it has many uses, and those are the
 special meanings in physics. When a force
  moves an object, that is what we now call
                   “work” :-)




                                    Next
I hope you have learned enough information
  about our topic today. Always remember,
   examples of these things are not simple
                 machines:




                                   Next
This is not a simple machine. This is
WALL-E. A complex robot machine.




                               Next
Neither is Bumblebee from
transformers. This is really a complex-
         transforming robot.




                                Next
Well yes. Washing machine makes
  your life easier, BUT this is not
identified as simple machine! It has
        complex functions in it




                               Next
Especially this! This is a machine. But
 this is machine gun, not for simple
 purposes. You know what I mean.




                                Next
BUT this. We are not machines, we
       are just SIMPLE :-)




    THANK YOU FOR TRYING OUR LEARNING OBJECT!
                   HOPE YOU HAD FUN! :-)
