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.
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.
What are the best materials for 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.
How do you make a mousetrap stronger?
Stiffening the Torsion Spring The more coils on a torsion spring, the greater the force output. That’s because the more that you twist it around, it’s as if you’re building and storing energy.
Are CD wheels good for mousetrap car?
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 2 hour car go faster?
Tablets and Movies. I am a big believer in limiting my kids’ screen time, except on road trips. The License Plate Game. Photo Journalists. Travel Journals. Video Games. The Official Map. Scavenger Hunt. The Deep Discussion.
What actually makes a car faster?
Now when it comes to how fast your car can go, that’s where the horsepower takes over. Horsepower is why certain cars with turbocharged V8 or better engines can hit top speeds of 300 mph. The force produced in the engine by the horsepower at relatively high rpm is what’s going to allow you to reach high speeds.
Is a longer lever arm better?
A longer input lever arm (location of the effort) gives a higher mechanical advantage. This is consistent with the common sense idea that you usually apply the effort force as far from the fulcrum as possible.
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.
How do you make a homemade car faster?
Upgrade Your Spark Plugs. Get New Electric Fans. Look At Your Exhaust System. Reduce Your Car’s Weight. Order A New Exhaust Header. Install A Larger Diameter Throttle Body.
What is the best length for a lever arm for 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.
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 are the best wheels for a mousetrap car?
CDs. CDs make one of the cheapest and easiest to use tires for a mouse trap car. The type of CD doesn’t matter, and you can even use DVDs if you like. However, you should make sure you don’t want to use the CD anymore.
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.
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.
What force makes a car go faster?
So, there are lots of other forces going on internal to the car. But the force directly responsible for making the car accelerate is the road’s friction.
Where should I place the mousetrap for the best performance for speed?
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 do you power a mousetrap car?
A basic mousetrap car is powered by attaching a string to the “snap” lever on the trap, looping the other end to a small hook on the axle, winding the string around the axle of the car pulling back on the lever and arming it.
