How do I make an effective mousetrap car?

How do I make an effective mousetrap car?
To adapt your mousetrap car for distance, use large, light wheels for less friction and greater inertia. For example, old CDs make great wheels to increase distance. If your car is a rear-wheel drive car, set the wheels on a narrow rear axle so the wheels turn more and travel further.

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.

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.

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!

Is overall weight important in mousetrap cars?
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.

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.

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.

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.

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.

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.

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.

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.

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.

Where should the mousetrap be placed on a mousetrap car?
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 mousetrap vehicle is in it’s fully wound position (as pictured bellow).

How does gravity affect a mousetrap car?
The force of gravity remains unchanged for all angles. The difference between the two forces causes the force down the ramp to increase. The greater the angle required to move the car, the more friction there will be acting against the car’s motion.

How do I make my mouse trap car faster?
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.
