How do you make a mousetrap car move?
Power to drive the wheels is provided by a mousetrap to which a wand and string is attached to the snap arm. Winding the string around the axle pulls back the snap arm and releasing the snap arm pulls the string, turning the wheels.
How do you make a mousetrap car better?
Adding a larger drive hub can improve pulling power. In some images there is a rubber tire on the axle, this acts as a “gear” and reduces string slippage. Use the longest lever available to extend the mousetrap arm as far as possible. The tip traverses a greater distance allowing more wheel wraps of string to play out.
What kind of string do you use for a mousetrap car?
The string has to be strong enough to handle the pulling force but flexible and thin enough to wind tightly around the drive axle. We recommend using a Kevlar based fishing line because its high strength. You should stay away from nylon fishing line and dental floss, these do not work well with mousetrap racers.
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 makes a mousetrap car go faster?
A speedy mousetrap car will have smaller wheels (faster acceleration), a shorter lever arm (increased torque, but smaller travel distance), a larger axle (increased acceleration) and will generally be smaller to decrease air resistance. Use a longer pole/stick attached to the mousetrap’s hammer.
What are the best materials for a mousetrap car?
What You Need:
- Wooden snap-back mousetrap.
- Duct tape.
- 4 eye hooks.
- Wooden dowel that fits inside the eye hooks.
- Heavy cardboard.
- Large and small rubber bands.
- Foam board (usually found at a craft store)
How long should a mousetrap car be?
The length of the string is about 25″. Therefore the string can be wrapped around the dowel 25/0.785 = About 31.8 times. So the minimum distance travelled will be the number of times the string can wrap around the dowel multiplied by the circumference of the wheels, which is 31.8 x 14.92 = 474.456″, or about 39.5ft!
Is it better to have a heavier or lighter mousetrap car?
A heavy mousetrap vehicle will required more pulling force than a lighter mousetrap vehicle in order to achieve an equal acceleration. Lighter mousetrap vehicles will require less energy at the start and can use longer lever arms for more pulling distance.
What happens if the mousetrap is mounted too close to the drive axle?
What happens if the mousetrap is mounted too far from the drive axle? You will lose pulling force or energy to friction. The energy goes too quickly and you lose pulling force.
What is the best mouse trap?

How does weight affect a mousetrap car?
mousetrap vehicle science Weight distribution can have a large effect on a vehicles performance, if the weight of a vehicle is concentrated to far away from the drive wheels there may be a greater tendency for slippage at the start line.
How do mousetrap cars reduce friction?
Try to have a minimum gap of 1/8 inch between the frame and any spacers (or wheels) in order to decrease any rubbing friction. Use thrust washers and graphite powder between spacers (or wheels) and the frame to help reduce the rubbing friction.
What does the string do on a mousetrap car?
A string is attached to the mouse trap’s lever arm and then hooked to the drive axle. The string has a loop knot tied at one end that is designed to “catch” a hook attached to the drive axle. The string’s loop knot is designed so that the string can release itself after the pulling force is spent.
