 It has nothing whatever to do with circles. Do you understand
calculus? Even vaguely?

 I don't want to be rude Roy, but this is INARGUABLE. I understand
that you don't think so, but when you roll a wheel connected to an
axle, the axle rotates as I say: linear movement on the ground divided
by axle height. It can't be anything else. The thing that is rolling
can be *any* shape... a bloody great long flat thing, a perfect circle
with point contract, or even a coil that squirms sideways like a
snake. It's just the way it is... basic maths taught in High School.

 So what am I supposed to do?

 I gave up educating you and I have no intention of being lectured by
an ignoramus. Believe what you like. I do not give a shit.
