A mousetrap is a small ‘automobile’, which have a form of ‘drive power’ being a mousetrap. A mousetrap involves the use of several traps, or enormous ‘Rat traps’, for extra power.
Mousetrap cars are usually used in ‘physics’ and other ‘physical classes’, it helps students to develop skills of solving problems, improve spatial awareness, to study the finances of time, and exercise cooperative activities. The style of mousetrap cars differs from the rest. In the mousetrap car style, you can find four wheeler cars as well as three wheeler cars. The best ways to increase the speed of your mousetrap car is to replace the string of the car and pull the axle with a rubber band. Large wheels can increase the distance travelled by using the same quantity of energy. Using extra strings, over and above what is required will cause the string to wind back around the axle, after the string runs out.
Spring Power
‘Helical torsion’ spring provides power to a mousetrap car. ‘Torsion springs’ is based on the angular form, which has been derived from Hooke’s law:
In this equation ‘T’ is torsion spring, the torque is wielded through the spring in Newton meters, and ‘θ’ is the angle of twist from its symmetrical position in radians. Torsion is invariable with Newton’s unit or radian; it is variably termed as ‘torsion coefficient’ of spring, torsion elastic modulus, or spring constant, which is similar to the torque requisite to wind the spring by an angle of ‘1 radian’. Torsion is equivalent to the ‘spring invariable’ of a ‘linear spring’.
The energy U (in joules), hoarded in a ‘torsion spring’ is: ’
When a mousetrap is gathered, the spring is primarily warped beyond its symmetry position, so that it applies momentous torque to the bar while the trap is blocked. If you want to create a mousetrap car, then just follow the following instructions.
Things required:
- Mousetrap
- Lightweight wood
- Screws
- Eye hooks
- Foam board or CDs
- Rubber material
- Wood or metal rods
- String
Instructions:
- Gather the framework. This podium will help you to find the base for the mousetrap, the ‘wheels’ and ‘gearing’ devices, which you would like to use in your mousetrap car design. You can use wood pieces which are light in weight and set up eye clips as axle carriers.
- Mount the mousetrap on the framework. Make holes in both the podium and the base of the mousetrap, and twist the mousetrap to the framework. The spring device on the ‘mousetrap’ works as the power supply for the car.
- Gather your light weight material and make the wheels for your car out of these materials, such as ‘foam board’, or old CDs. Join rubber bands, balloons or other rubber material as stride. Use wheels that are comparatively large for the axle size.
- Set up the wheels and axles. Axles can be made of wooden rods, or synthetic or metal rods. Make sure that they are straight and in equilibrium; otherwise the mousetrap car can shake it apart.
- Join the ‘drive string’ to your mousetrap. Put down the end of the string which will be twisted across the drive axle loose, so that it discharges when it reaches the end. If you won’t put down the end of the string loose, it will start to wind back at the end of its travel and break the speed of the car.
- Secure the trap and twist the string across the drive axle. Discharge the trap to send the mousetrap car down the road.
Tips and Warnings:
- Use lightweight equipments to take full advantage of coasting distance. Twist the string strongly around the axle so it won’t be able to slip. Be watchful of the mousetrap. You can injure yourself or be otherwise hurt.

Heard about this site from my friend. He pointed me here and told me I’d find what I need. He was right! I got all the questions I had, answered. Didn’t even take long to find it. Love the fact that you made it so easy for people like me. More power
Uhhhm, My class is doing this in science and we can’t figure out if it should be heavier or lighter…
