    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.

    Any clues? Thanks in advance.

    I've attached a sketch. The complete track is drawn in red.

    Actually you are dealing with a right triangle with the distance between the centers as hypotenuse. One leg of the right angle is the straight part of the track.

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