Making The Vehicle Faster

1. Thicken the axle: Wrapping some tape radially around the axle or adding a spool. It may be surprising as to how much faster this makes the vehicle.
2. Use smaller wheels. They will require less force to complete a rotation.
3. Make the vehicle lighter.

What is the fastest mousetrap car design?

The Speed-Trap Racer is the fastest mousetrap powered racer anywhere and was designed after Doc Fizzix’s own record-setting mousetrap racer that traveled 5 meters in 1.2 seconds.

How do you make a mousetrap car aerodynamic?

Design your mousetrap racer so that it can slice through the air with the least amount of resistance; design your vehicle to be aerodynamic. Try sanding and painting wood frames in order to cut down on the air resistance. Slow moving mousetrap vehicles will experience less friction than faster moving vehicles.

### How long should the lever arm be on a mousetrap car for speed?

For maximum speed, position the mousetrap 2 1/4 inches from the drive axle and cut the lever arm to a length of 4 1/4 inches. The lever arm can be cut using a dremel tool or by using a fine tooth hobby saw. The lever arm should always be “just” long enough to reach the drive axle or performance will be compromised.

Why is my mousetrap car not moving?

If a mousetrap vehicle is struggling to move and/or needs more acceleration then the lever arms can be shortened in order to increase the pulling force. Keep in mind that you will also have to reposition the mouse trap closer to the drive axle or the system will not work as intended.

What is the equation for figuring out your speed with the mousetrap car?

The work done on the mousetrap arm is found using the formula W = F  d, where F is the force (in Newtons) applied to the mousetrap car spring arm and d is the distance (in m) through which the force is applied.

## How long should the lever be on a mousetrap car?

Build your mousetrap powered car using a 12-inch lever arm and make sure not to glue the mousetrap to the frame.

How long should the arm be on a mousetrap car?

How long should the string be on a mousetrap car?

about 25″
The length of the string is about 25″. Therefore the string can be wrapped around the dowel 25/0.785 = About 31.8 times.
