# Math Help - Tank Tanks

1. ## Tank Tanks

Hi, I'm running a physics simulation using tank tracks over two wheels in 2D, what I need help with is the maths to work out how many tracks I'm going to need. I know the following:

1. The radius/circumference of the front and rear wheel.
2. The distance the wheels are apart.
3. The length of each track.

To calculate the two different arcs determine the angle $\mu$ which you can find in both circles.
