Mousetrap Powered Racer 4/4 Modeling 3

by

Introduction

When thinking about how to calculate the distance that your mousetrap vehicle will cover under power, there are a few things to consider.

1. Length of the mousetrap arm

2. Circumference of the driving axle

3. Circumference of the driving wheel

If all of these factors are known, you can accurately calculate the probable distance that the mousetrap car might cover.

(This lesson will not go into friction coefficients or the vehicle's ability to gain momentum. We will only be discussing the theoretical relationship of the three parts of the car.)
