How to Build A Mousetrap Car: 11+ Free Plans Inspiring DIY Projects

mousetrap car design

You will use the modeling and simulation capabilities of Fusion 360 to iterate and optimize your design a mousetrap car. You can do this by simply taping or gluing the dowel to the mechanism on the mousetrap, or you can 3D print the adapter I have designed. This adapter allows for secure connection to the mousetrap as well as a a place to glue in a 1/4 dowel. Wrapping a balloon around the pen fixed in the earlier step, try to fold it in a way that it is seems something like a wedge on the edge of the pen.

I will try to present this in a fun an easy to understand manner. In looking at the labs schools are doing with mousetrap cars it appears to be related with recording total distance and/or computing the acceleration during the run. A background in force and motion will be helpful which will include a discussion of Newton’s Laws.

Changing the length of the lever arm does not change the total energy and/or the torque produced by the mouse trap but it does change the pulling force applied to the drive axle. Longer lever arms will have less pulling force than shorter lever arm but longer lever arm will pull more string from the drive axle than shorter lever arm. Changing and/or attaching a lever arm to the mousetrap is the number one way to control a mousetrap vehicles performance.

If you are building a super-fast speed-trap racer then rotational inertial is one of the most important concepts you will need to understand. Because most top-speed contest are performed over a set distance friction is not as big of an issue as it would be in a maximum travel-distance contest. Non-drive wheels should be as small and as light as possible.

How To Get Slime Out Of Carpet: Effective Methods for Removing Slime – A Step-by-Step Guide

In the mousetrap car one axle acts like a pulley as the string is wrapped around it. The diameter of axle in relation to the diameter of the driving wheels is the mechanical advantage. During the first few years of working with my science related project ideas it was mainly about just getting the students to successfully build and operate the projects. Through workshops I have taught a fairly large number of mousetrap cars of my design have been built.

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. Heat and sound are forms of friction that will eventually absorbs all the energy from your mousetrap racer and cause it to come to rest.

In case this intrigues you, the text below would probably quench your thirst of knowledge about mouse trap cars. Friction is a force that acts against the motion of all moving objects. As a general rule of thumb the more moving parts a device has the greater the force of friction acting against the system. The first step in deceasing friction happens in the planning and designing of your mousetrap vehicle.

Step 2: Design

Many times formulas are based on units other than those you have collected your data with. My spring scale does display Newtons also but grams are a much smaller unit which helps in taking more accurate measurement. Latest version of the Quicky Mousetrap using foam block chassis for a summer class entitled “Engineering Through Models”. Let go of the string (after making sure all hands are out of the way!). Remove any metal or plastic teeth on the mousetrap with pliers.

Mousetrap Cars

I don’t pretend to play one online, I’m just a parent who was trying to help my kids with their project and this is what worked for us. If you have suggestions for readers on how to make the car even better I would love for you to share those in the comments. Leave links to your own mousetrap car projects that worked too because being parents is a team effort. In conclusion, mousetrap cars are a great way to entertain yourself for free. You can even enter your car into racing competitions if you enjoy it.

Test spin your mousetrap racers wheels in order to see how friction-free they spin. If the wheels stop spinning fairly quickly then you will need to find ways to reduce the axle friction. Learn all the secrets to building your own record setting mousetrap powered dragster. You cannot build a winning mousetrap racer until you know the basics. Tie a cable tie to the drive wheel dowel, off-center and near the frame (this will be explained when winding up the string). Pull it as tight as possible, then cut off the excess (picture 3).

Cut the excess from the zip tie so you are left with a small attachment point. You may add hot glue at this point to add stability if necessary. Add a spacer and then insert the axle into the body of the car.

You might remember from high-school learning the principles of basic physics and then making a car like this yourself. Rober shows you how to win the mousetrap challenge as well as carefully explaining the principles behind it. Fit two small wheels onto the ends of the dowel; wrap the ends of the dowel in tape if the wheels are slipping off. If the wheels fit loosely, then wrap one layer of of masking tape around the end of the dowel before putting the wheels on (picture 2).

When you step on the platform of the trap, it releases the bar, which holds down one or more wheels. These wheels are affixed to axles that are connected to the mousetraps. They run along a track made out of duct tape, letting it go forward. The Mousetrap Car is a toy car that can be made from household items. It is powered by the force of gravity and the weight of the mouse trap.

This will help the axle later going through them to be somewhat straight. Take care that you do not crack the mouse trap more than required. This is very important when it comes to mouse trap car instructions. One of the issues we faced was getting the axle (the wood dowel on the back wheels) to rotate. The second car we made we had seen a tutorial for a small juice box straw that had a wood skewer running through it.
