What are some features of a mousetrap car made for long distance?

What are some features of a mousetrap car made for long distance?
Long-Distance Racer: Most top long-distance mousetrap racers will have large drive wheels, small drive axles, and long lever arms. Long-Distance Racers will be slow moving so as to decrease friction as much as possible and extend the pulling distance of the mouse trap.

Are big wheels better for a mousetrap car?
Wheels and Axles Larger drive wheels will have a greater travel distance per each turn compared to smaller drive wheel. It would make sense to use a super huge drive wheel so for each turn of this massive drive wheel the mousetrap vehicle will travel an incredible distance.

What is the most important thing to keep in mind when designing a mousetrap car?
Traction is a major issue when it comes to building a super fast speed-trap racer. If there is not enough traction between the drive wheels and the floor then your mousetrap racer will not be able to accelerate as designed. Use drive wheels that provide a lot of traction on the floor.

How does the length of the lever affect a mousetrap car?
By adjusting the length of the mouse trap’s lever arm, you can vary the force that is applied to the wheels of your car. Long lever arms decrease the pulling force while short arms increase the pulling force. The longer the length of the lever arm that you use, the more string you can wind around the drive axle.

Are CDs good wheels?
Because CDs and DVDs are some of the best wheels you will ever find for building a long distance mousetrap powered vehicle. CD/DVD wheels can slice through the air with very little air resistance and they have very little rotational inertia.

How do you make a mousetrap car stop at a certain distance?
Setting the braking system is simple and easy: just place the vehicle at the finish line with the wing nut in the lock position, roll the vehicle back to the start line and the wing nut is set to the exact starting position.

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 long should dowel be on mousetrap car?
If you have larger drive wheels, these should go on the rear axle and the smaller wheels on the front axle. Your axle dowels should extend past your wheel about 1″ (2.5 cm). around your dowel just outside each of wheels. The elastic band will keep the wheels from falling off of the car.

How do you increase the mechanical advantage of a mousetrap car?
Two ways to increase the mechanical advantage of the car is having the lever be longer and having larger wheels (or thinner axles because it really depends on the ratio between the wheels and the axles). However, these two ways both have their advantages and disadvantages.

Is 3 wheels better than 4 in mousetrap car?
So what is better, three wheels or four wheels? The answer depends on the contest, if we are to build a super fast accelerating speed-trap racer then over coming rotational inertia is one of the main objectives therefor three wheels will always do better than four wheels when it comes to performance.

Why is my mousetrap car not going far?
Vehicle weight is an important factor to consider reducing if your mousetrap vehicle is not traveling far enough. The greater your mousetrap vehicle weighs, the shorter the distance it will cover and the speed it will travel. This consequence is due to the limited energy within the mousetrap.

What kind of string is best 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.

What are the best materials to make a mousetrap car?
A mousetrap car can be made from cardboard or balsa wood with CD’s for wheels and axles of wood or brass tubing. Power to drive the wheels is provided by a mousetrap to which a wand and string is attached to the snap arm.

Is overall weight important for a mousetrap car?
Weight. Vehicle weight is an important factor to consider when building your mousetrap vehicle. Depending on the rules of your competition and your available materials to construct your device, the minimum weight you can achieve will vary.

How far can a mousetrap car go?
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!

What is the basic design of a mousetrap car?
The most basic design for propelling a mousetrap racers is to tie one end of a string to a mouse trap’s snapper arm and then attach the other end of the string to a drive axle. By turning the drive axle the string is wound around the drive axle causing the mouse trap’s spring to compress and store energy.

What is the best wood for a mousetrap car?
Balsa wood, pine, or bass wood are excellent choices although balsa wood is somewhat brittle and hard to drill holes into without ripping. Other materials can also be used for making a light weight strong and stiff frame. These include Styrofoam, corrugated cardboard, plastics, aluminum and brass tubing.

What happens if the mousetrap is placed too far from the drive axle?
6. What happens if the mousetrap is mounted too far from the drive axle? You will lose pulling force or energy to friction.

How do you make a mousetrap car go faster and further?
If you haven’t realized it yet, increasing the length of the lever arm attached to the mousetrap, increases the total mechanical advantage of the car. Therefore, to increase your car’s speed, you can reduce the length of the lever arm attached to the mousetrap.

What is the best car to build for drag racing?
10/10 1981-1988 Dodge Diplomat. 9/10 1991-1996 Chevrolet Caprice. 8/10 1998-2012 Ford Crown Victoria. 7/10 1973-1977 Chevrolet El Camino. 6/10 1988-1998 Chevrolet C/K 1500. 5/10 Chevrolet S10/GMC Sonoma (Any Year) 4/10 1994-2004 Ford Mustang. 3/10 1970-1976 Plymouth Duster.
