Please put me out of my misery. I've been bothered over the Train Wheel Quandary for some time. I think I have a mental block. Of course I understand that the two circumferences are different and I understand that the distance the two points A and B travels are quite different. This is all clear.

But still if you measure the distance A --- A this will be the circumference of the larger circle. So why if you measure the line B----B is it not the circumference of the smaller circle.

Appreciate your clarification.

Thanks in advance.
