How far can a mouse trap car travel?

This most basic design can propel a vehicle several meters for any first-time builder. But in order to build vehicles that can travel over 100 meters or extreme speed cars that can travel 5 meters in less than a second,you must learn about some of the different variables that affect the performance of a mouse-trap car.

How do you increase the distance on a mousetrap car?

Use a narrow rear axle. If your rear axle is extremely skinny, your mousetrap car will be able to turn it more times for the same length of string than it would if it were wider. This translates to turning your rear wheels more times, meaning greater distance!

How long should a mouse trap 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.

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

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.

Does a faster mousetrap car mean a further distance?

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.

Is weight important in a mousetrap car?

Reduce the most friction you can because the more friction the more energy is lost in propelling the car. Mass should also be taken into account, the more the car weighs the more energy from the mousetrap spring will be used so it’ll be best to make the car light weight.

Why is it better to have large wheels for the drive axle on a mousetrap car?

Larger drive wheels will have a greater travel distance per each turn compared to smaller drive wheel. The smaller the diameter of the drive axle in comparison to the diameter of the drive wheel the more force that will be required to accelerate the vehicle but the greater the distance of travel per rotation.

What makes a mousetrap car go faster?

Where should I place the mousetrap for the best performance for distance?

For optimal performance the mouse trap should be positioned on the chassis so that the tip of the lever arm falls directly above the drive axle when the mouse trap is in the fully wound position (as pictured bellow). If the mouse trap is not aligned properly with the drive axle energy will be wasted off the start.

How do you slow down a mousetrap car?

If instead the mousetrap vehicle is shins it’s wheels when placed on the ground, or traveling two fast causing it to have to much friction, you may have to increase the length of the mouse trap’s lever arm and reposition the mouse trap away from the drive axle in order to slow the vehicle down and decrease the pulling …

What makes a mousetrap car go fast?

Is 3 or 4 wheels better for a mousetrap car?

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.
