How do you make a mousetrap car go super far?

How do you make a mousetrap car go super far?
lever arm length 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 makes a mouse trap car 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.

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 best length for a mousetrap car?
Max Length – 45 cm. Max Width – 20 cm. Height – 20 cm. Min ground clearance – 4 cm.

Is wood or cardboard better for 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.

Is weight important in a mousetrap car?
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.

Why do mousetrap cars use CDs?
Why do so many mousetrap cars use CD/DVD for 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.

What factors can prevent a mousetrap car from rolling far?
The smaller the coefficient of friction, the more efficient your mousetrap car and the greater the travel distance will be. Finding the theoretical rolling friction requires placing your mousetrap car on a smooth and flat board or ramp.

How do you reduce friction on a mousetrap car?
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 do you put in a mousetrap car arm?
In most cases brass tubing and brass brazing rods make excellent lever arms because of their high-strength and light-weight. Wood can also make for a very strong and light-weight lever arm if it is used properly (see making a super long lever arm).

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.

Should a mousetrap car be heavy or light?
Lighter mousetrap vehicles will require less energy at the start and can use longer lever arms for more pulling distance. Always use lightweight components when building a mousetrap vehicle. bonus tip: lightweight mousetrap vehicles require less pulling force off the start.

What is the best amount of wheels for a 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.

Does the length of a mousetrap car matter?
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.

Why is my mousetrap car not going straight?
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!

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 adjust the pulling force of the mousetrap?
Changing the length of the mouse trap’s lever arm controls the pulling force and the amount of string that can be wound around the drive axle. Making the length of the mouse trap’s lever arm longer will decrease the pulling force but increase the amount of string that can be pulling from the drive axle.

How long should the lever arm be on a mousetrap car?
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.

What cars are made out of fiberglass?
Also known as GRP or fibreglass, it was discovered accidentally by Owens Corning in the 1930s. The Glasspar G2 kicked off a fibreglass car body boom, GRP quickly becoming the material of choice for countless low-volume car makers such as Lotus, Alpine, TVR, Matra, Ginetta and more.
