What makes a mousetrap car go?
Mousetrap Cars: Propulsion A mousetrap powered car is a vehicle that is powered by the energy of a wound-up mouse trap’s spring. By turning the drive axle the string is wound around the drive axle causing the mouse trap’s spring to compress and store energy.
How do you make a mousetrap car go faster?
Making The Vehicle Faster 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. Use smaller wheels. They will require less force to complete a rotation. Make the vehicle lighter.
How do you propel a mousetrap car?
Once the mouse-trap’s arm is released, the tension of the mouse-trap’s arm pulls the string off the drive axle causing the drive axle and the wheels to rotate, propelling the vehicle.
Why is my mousetrap car not going straight?
If your mousetrap car does not travel straight energy is also being wasted to over come the force of friction turning the vehicle’s wheels. If a mousetrap vehicle is not traveling straight then there is one reason and one reason only: the front and rear axles are not parallel to one another!Jan 21, 2012.
What makes the car go fast?
The motive force for a car is the engine. Every engine produces an amount of work-energy measured in mechanical horsepower. One horsepower is 550 foot-pounds per second. More power in generation from the engine means more power available to turn the wheels faster on the car.
How long should a mousetrap car be?
The ideal size for an ultra big wheel on a long distance mousetrap racer seams to be somewhere between 10 and 15 inches. And the ideal size for a drive wheel on a speed-trap racer seams to be between 2 and 3 inches but no more than 4 inches.
What is the fastest mousetrap car?
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 rat trap car go far?
Mousetrap cars will go farther if the spring has more distance from the back wheels. Create traction on the wheels. Add rubber bands, or tape around the wheels to give them better traction. The better the wheels can grip the floor, the farther the mousetrap car will go.
How does a rat trap car work?
A basic mousetrap car is powered by attaching a string to the “snap” lever on the trap, looping the other end to a small hook on the axle, winding the string around the axle of the car pulling back on the lever and arming it. There are many of variations of how to attach a mousetrap to drive the wheels.
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.
How do you find the force of a mouse trap?
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. You found the force applied using a spring scale and should have it in the table above.
What can you use for wheels on a mousetrap car?
As you might guess, the materials used to build mousetrap-powered cars are light out of necessity. Foamcore board or balsa wood are often used for the body. The wheels can be off-the-shelf radio-controlled car wheels, but many builders use blank CDs or DVDs because their thin edges reduce friction.
How do you make a rubber band car move?
Procedure Loop a rubber band through itself around the middle, exposed part of the wooden skewer (where you cut out a notch in the cardboard and straw). Tape the rubber band to the skewer to prevent it from slipping—when the skewer rotates, the rubber band should rotate with it.
How can I raise my car pickup?
The Best Ways To Make Your Car Go Faster Upgrade Your Spark Plugs. Get New Electric Fans. Look At Your Exhaust System. Reduce Your Car’s Weight. Order A New Exhaust Header. Install A Larger Diameter Throttle Body.
How do you improve 0 to 60?
10 tips for increasing 0-60 speeds for your vehicle: Reduce any and all non-essential weight from the vehicle (spare tires, jack, tools, racks, rails, rear seating, door panels). Open up the exhaust. Add a supercharger. Stiffer suspension and bushings. Change your tires to a stickier compound.
What are 4 ways you can make your mousetrap car go further?
Tips If the string is just wrapped around the axle, the car may barely move. Use the longest lever available to extend the mousetrap arm as far as possible. Reduce friction on the axle by minimizing the surface area of the support that contacts the drive axle. Reduce shock by using a bit of sponge as simulated cheese.
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.
Are Bigger wheels better for a mousetrap car?
By changing the size of the drive wheel(s) you can speed-up or slow-down your mousetrap vehicle. Larger drive wheels will have a greater travel distance per each turn compared to smaller drive wheel.
What is an axle hook on a mousetrap car?
An important part of a mousetrap vehicles propulsion system is the axle hook. If the string does not properly release from the drive axle the string will rewind around the drive axle and cause the mousetrap car to come to an instant stop.
