How do you build a speed and distance mousetrap car?

How do you build a speed and distance mousetrap car?
The greater the ratio of the diameter of the axle to the wheel, the less force will be required to accelerate the car. In other words, you should match a larger axle with a smaller wheel to increase acceleration. Conversely, a mousetrap racer built for distance should have a smaller axle and a larger driving wheel.

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.

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.

Where should I place the mousetrap for the best performance for distance?
For maximum travel distance, glue the back of the mousetrap 10 1/4 inches from the drive axle and do not change the length of the lever arm. 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.

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.

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.

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.

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 often should you change the bait on a mousetrap?
Q: How often should the rodent baits in bait stations be replaced if they still appear fresh? A: Most recommendations suggest changing out rodent baits on a four- to six-week schedule on a need-it-or-not basis.

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 far can a mousetrap car travel?
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 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.

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.

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.

Why are CDs good for mousetrap cars?
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.

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.

What is the most effective bait for a mousetrap?
Sweet or fatty foods are favorites of these rodents, so peanut butter, soft cheese, or wet cat food often work well. In general, a small amount of a sticky bait is most likely to make a mouse trigger the trap.

Can a mouse be too smart for a trap?
No, they are not that smart, but they may start to avoid traps for other reasons. If this happens, it can appear that the mice have figured out what happens to any one of them who enters the trap. The truth is usually more down to earth. Mice have a very keen sense of smell.

What will make a mousetrap car go 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.
