Try not to have any extra frame material beyond what's necessary to keep your mousetrap and wheel axles in place. In the design, the snapper of the mousetrap is tied with a string; the other end of which is tied to the axle at the rear end of the car. The mousetrap is tied to a string, which allows it to move long distances. For maximum distance, you'll want to be using as close to 100% of your mousetrap's power as possible. Try to copy the design of a top fuel dragster when building a super-fast speed-trap racer. Slip the knot over the dowel and tighten it while making sure it is over the notch.

Generally, glue will hold just as well as nails, which can add unnecessary weight. Holding the string tightly, set the car on the ground and carefully let go of the trap — the string should be wound tight enough that it holds the trap in place. Rober visits his friend, the world record holder for mouse trap car distance, to find out how he does it. Make sure that the knot is tight. Use a long rod to attach to the mousetrap spring.

First, wind the string so that the wheels are spinning forward. The lever shouldn't bend at all under the stress of the string — this represents wasted energy. You will need to keep the lever arm indicated in the picture notes. Mousetrap car made for 12th grade science class project. Put the large wheels on the back of the car, opposite the snapper arm. Set the trap and watch the car roll. At some point a drive wheel can be so large that there is not enough force from the mouse trap to keep the wheel turning.

I decided to use balsa wood for the sake of making my car lightweight, but it also made the car seem less durable. When the jaw trap closes, it pulls the string along with it. Make the frame long and narrow. So you should make sure that your driving front wheel is as small as possible. Improvements to my car would be to tweak the alignment so it would track better in a straight line and apply dry graphite lubricant to the wheel axle friction points to roll better.

As the size of the drive wheel increase the torque required to start a wheel turning also increase. The longer distance between the trap and the wheels, the better — more distance means you'll be able to loop more string around the axle for just a little extra slow and steady pulling power. Smaller power outputs produce less wasted energy and have greater efficiency. It is always important to understand the relationships between variables but never over exaggerate any one concept. Experiment to see how short you can get the lever while maintaining control of the car. The above procedure used rubber bands to provide traction; can you think of a better way? I'm doing this for an 8th grade science project and the model looked innovative and creative to me.

Because the number of moving components increases the friction point look for ways to simplify the design as much as possible. The button above links to a wiki page that explains how to build a mousetrap car, if you would like to build one. To prevent this from happening, make sure that as little surface area as possible is exposed. 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. Your car can lose a lot of energy at the point where the axle touches the frame. In order to walk forward your foot needs to be able to push against the floor and the floor has to push back.

Next, mark two dots on one piece of balsa wood. See some ideas at the end of the project. Add another stick on top the overlaps both below. You may want to add a little super glue on the end of the dowel, but if you do remember that once it is on it doesn't come off. The distance it traveled in the contest we had against the class was 13 meters. Eliminate friction between the axle and the frame. Use rubber bands for this purpose.

This added weight will increase the torque of the axle. Your mousetrap car is now ready to race. As a result, it will go slower, but move further. To do this, I clamped the parts with pliers and yanked the pieces out. This is done to help create traction. This article was co-authored by our trained team of editors and researchers who validated it for accuracy and comprehensiveness. You may also want to put duct tape over the straws for the added strength.

Try applying a lubricate, like graphite powder. Most of the time, for mousetrap car assignments, all students will be required to use the same size of mousetrap so that everyone's car designs have the same amount of power. To prevent this from happening, make sure that as little surface area as possible is exposed. Most record-setting long distance mousetrap vehicles are geared so that they have the smallest possible energy consumption rate or power output in order to maximize the pulling distance. The goal with any speed trap racer is to use as short a lever arm as possible or just before the point where the drive wheels spin out. The car works when one end of a string is tied to the arm on the mousetrap and the other end is wound around an axle. When the mousetrap is released, the long lever creates a mechanical advantage.
