How do you make a fast mousetrap car?
Making The Vehicle Faster Thicken the axle: Wrapping some tape radially around the axle or adding a spool. It may be surprising as to how much faster this makes the vehicle. Use smaller wheels. They will require less force to complete a rotation. Make the vehicle lighter.
What can be used as wheels for a mousetrap car?
As you might guess, the materials used to build mousetrap-powered cars are light out of necessity. Foamcore board or balsa wood are often used for the body. The wheels can be off-the-shelf radio-controlled car wheels, but many builders use blank CDs or DVDs because their thin edges reduce friction.
What materials do you need to build a mousetrap car?
What You Need: Wooden snap-back mousetrap. Duct tape. 4 eye hooks. Wooden dowel that fits inside the eye hooks. Heavy cardboard. Large and small rubber bands. Foam board (usually found at a craft store) String.
What is the fastest mousetrap car?
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 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.
How long should a mouse trap car be?
It is always important to understand the relationships between variables but never over exaggerate any one concept. The ideal size for an ultra big wheel on a long distance mousetrap racer seams to be somewhere between 10 and 15 inches.
Are CD wheels good for mousetrap car?
Mouse Trap Cars: CD/DVD Wheels. Learn more about using DVDs/CDs as wheels on your mousetrap racer. DVDs/CDs make great wheels because they can slice through the air with very little resistance. Because CDs and DVDs are some of the best wheels you will ever find for building a long distance mousetrap powered vehicle.
Do snap mouse traps work?
Traditionally, snap traps have been popular for killing mice and rats swiftly. If you’re trying to bring down the population of house mice and deer mice in your area, snap traps can work especially well. When used correctly, the quick trigger system of a snap tap can help manage large infestations.
How do you make a mouse trap out of a bucket?
The Process: Drill holes at the top of the bucket, on 2 opposite sides. Drill holes in the middle of each flat side of a soda can. Insert a dowel through the bucket holes and the soda can holes, to end up with a unit that looks like the image. Bait with peanut butter and add a ramp for the mice to get up.
What is an axle hook on a mousetrap car?
An important part of a mousetrap vehicles propulsion system is the axle hook. If the string does not properly release from the drive axle the string will rewind around the drive axle and cause the mousetrap car to come to an instant stop.
How do you make a rubber band car move?
Procedure Loop a rubber band through itself around the middle, exposed part of the wooden skewer (where you cut out a notch in the cardboard and straw). Tape the rubber band to the skewer to prevent it from slipping—when the skewer rotates, the rubber band should rotate with it.
Why is my mousetrap car not going straight?
If your mousetrap car does not travel straight energy is also being wasted to over come the force of friction turning the vehicle’s wheels. 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!Jan 21, 2012.
Should a mousetrap car be heavy or light?
Above all, your car should be light. The smaller the mass of your car, the better — every gram or milligram you can shave off of your car’s frame is a little further your mousetrap will be able to push your car.
Should the string be tied to the axle Why or why not?
The string must not be tied to the axle. If the string is tied to the axle, it will begin to rewind itself and will cause your car to come to a sudden stop. In order to achieve maximum performance from your mouse-trap car, it is important that the pulling string does not slip off the drive axle prematurely.
What kind of lever is a mousetrap car?
When you set the mousetrap, you are using a second-class lever. The load is the arm of the spring that is being pushed down to compress the spring. The effort force is your fingers on the end of the snapper arm, and the fulcrum is the pivot point in the middle of the trap.
How do you increase the friction of a mousetrap car?
Larger diameter axles have greater friction when compared to the same axle of a smaller diameter. With a smaller diameter axle the force of friction is applied closer to the center of rotation and applies less torque than a larger diameter axle. Try to select axles that are equal to or less than 3/16 inch in diameter.
How do you find the force of a mouse trap?
The work done on the mousetrap arm is found using the formula W = F d, where F is the force (in Newtons) applied to the mousetrap car spring arm and d is the distance (in m) through which the force is applied. You found the force applied using a spring scale and should have it in the table above.
