Quote:
The conveyer belt is designed to exactly match the speed of the wheels at any given time, moving in the opposite direction of rotation.


This part of it is entirely self consistant, though it seems otherwise. Neither half of the statment says anything to counter the other, as long as it is accepted that the first half of the statment is talking about net speed (linear) while the second half is talking about rotational speed. Two compleatly different things.

The belt can move to do both, match the speed of the wheel (linear), and move to oppose the rotation of the wheel at the same time. It's the same motion for the belt. The net effect is that the wheel is never allowed to spin.
