Design Project Description
OBJECTIVES:
Conceive, Design, Implement, Operate a vehicle in modern
team-based environment. The vehicle will be powered solely by
the energy of one standard-sized mouse trap, (1 3/4" X 3 7/8"),

3. and will enter a two-event competition:
1) traveling the longest linear distance, and 2) traveling a 5-
meter linear distance in the shortest amount of time.

DEFITIONS AND REGULATIONS:
By definition, a vehicle is a device with wheels or runners used
to carry something, (e.g., car, bus, bicycle or sled). Therefore,
launching a ball, (e.g., marble) from the mousetrap will be ruled
illegal.
1. The device must be powered by a single Victor brand mouse
trap (1 3/4" X 3 7/8") .
2. The mousetrap can not be physically altered except for the
following: 4 holes can be drilled only to mount the mousetrap to
the frame and a mousetrap's spring can be removed only to
adjust the length of the its lever arm.
3. The device cannot have any additional potential or kinetic
energy at the start other than what can be stored in the
mousetrap's spring itself. (This also means that you cannot push
start your vehicle.)
4. The spring from the mousetrap cannot be altered or heat
treated.

4. 5. The spring cannot be wound more than its normal travel
distance or 180 degrees.
6. Vehicles must be self-starting. Vehicles may not receive a
push in the forward direction or side direction.
7. The vehicle must steer itself. Measurements of distance will
not measure the total distance traveled only the displacement
distance.
8. Distance will be measured from the front of the tape at the
starting line to the point of the vehicle that was closest to the
start line at the time of release.
9. In its fully extended form, the vehicle must fit inside a 8” x
14 ” x 8” box.
10. The instructor has the final decision as to the
appropriateness of any additional items that might be used in
the construction of the racer.
RUNNING THE CONTEST:
1. The race track is the hallway floor outside the classroom.
2. Each team contestant will be given three attempts for the
speed event and the distance event. The winner will be the team
with the highest winning index, which has this formula: winning
index = (best time of the class/your best time of the three
attempts) + (your longest distance of the three attempts/longest
distance of the class). Any ties will be decided by a single run
off between the racers which tied.

What is a Mousetrap Car?A vehicle powered by the spring
device of a mousetrap
The mousetrap acts as a third-class lever
fulcrum
applied force
resultant force (load)
*
What is a Mousetrap Car?How does the power source work?The
spring propels the hammer, which causes an enormous release

6. of energyThe hammer is connected to a string that is wound
around the drive axleThe string unwinds as the hammer snaps–
making the car roll!
(from Doc Fizzix’s Mousetrap Powered Cars & Boats)
*
Scientific ConceptsPotential Energy: energy that is stored
within an object, not in motion but capable of becoming
activeYou have stored potential energy (in the spring) when
your mousetrap is set and ready to be released Kinetic Energy:
energy that a body possesses as a result of its motion Potential
energy becomes kinetic energy as the mousetrap car begins to
moveSome of this energy goes to friction– the rest makes your
car go!
*
Scientific ConceptsForce: an action that causes a mass to
accelerateTo change the motion of your mousetrap car, you
must apply a forceTo increase the acceleration of you car, you
must increase the force or decrease the mass (Newton’s Second
Law)Friction: the force that opposes the relative motion of two
surfaces in contactFriction will slow– and eventually stop– your
mousetrap carFriction occurs between the wheels and the floor
and between the axle and the chassis

7. *
Scientific ConceptsTorque: can informally be thought of as
"rotational force" or "angular force" that causes a change in
rotational motionIn your mousetrap car, the snapper arm applies
a force to the drive axle through the pulling string. This in turn
causes a torque to be produced around the drive axle.
Power: the rate at which work is done or energy is usedIn a
mousetrap car, the same amount of energy is used regardless of
its speed – only the rate of use changesFor distance, you want to
use energy slowly; for speed, you want to use it more quickly
(from Doc Fizzix’s Mousetrap Powered Cars & Boats)
*
Construction HintsWhen building a mousetrap car, there are a
number of variables to considerWeight of the carPlacement of
the mousetrap Length of the snapper arm and the stringSize and
type of wheelsWheel-to-axle ratioYour design decisions will
depend on the goal of your car: distance or power
*

8. *
Weight of the CarFor all cars, you want to build the lightest
possible vehicleLighter vehicles will require less force to begin
moving and will experience less friction than heavier
vehiclesHowever, if your car is too light, it will not have
enough tractionThis will cause the wheels will spin out as soon
as the trap is released
*
Length of the Snapper Arm and the StringLong snapper arms
and short snapper arms release the same amount of energyThe
difference lies in the rate at which the energy is released (power
output)For distance cars, try a long arm. Longer arms will
provide less force, but more distance. With a longer arm, more
string will be pulled off the axleThis causes the wheels to turn
more times and allows the vehicle to cover more distanceFor
power cars, try a shorter arm. Shorter arms will provide more
force and power output, but less distance.These cars need the
power to get up the ramp!
(from Doc Fizzix’s Mousetrap Powered Cars & Boats)

9. *
Length of the Snapper Arm and the String (cont.)For all cars,
the lever arm should just reach the drive axle when it’s in the
ready positionWhen the string is wound, the place where the
string is attached to the snapper arm should be above the drive
axleThis will maximize your torque as your car takes off
(maximum torque occurs when your lever arm and string form a
90° angle)
(from Doc Fizzix’s Mousetrap Powered Cars & Boats)
Correct length
Too long!
*
Length of the Snapper Arm and the String (cont.)The string
length should be a little shorter than the distance from the lever
arm to the drive axle when the trap is in the relaxed
positionThis will allow the string to release from the hook– and
prevent tangles!
(from Doc Fizzix’s Mousetrap Powered Cars & Boats)
*

10. Placement of the MousetrapFor distance cars, place the trap
farther from the drive axleYou’ll sacrifice pulling force, but get
more distanceFor power cars, place the trap closer to the drive
axleYou’ll sacrifice distance, but get more pulling force
(from Doc Fizzix’s Mousetrap Powered Cars & Boats)
Drive axle
Distance placement
Power placement
*
For distance cars, larger wheels will cover more distance per
rotation than smaller wheelsFor power cars, make sure your
wheels have good traction so they don’t slipYou can increase
traction by covering the edges of the wheel with a rubber band
or the middle of a balloon
Size and Type of Wheels
(from Doc Fizzix’s Mousetrap Powered Cars & Boats)
*
Wheel-to-Axle RatioFor distance cars, a large wheel-to-axle
ratio is bestA large wheel with a small axle will cover more
distance each time the axle turnsFor power vehicles, a smaller
wheel-to-axle ratio is bestIncreasing the size of the axle will

11. decrease the wheel-to-axle ratioThis will increase the torque
and give you more pulling force for every turn of the wheel
