The result is that only under specific conditions either one of the disks can seize rotating after the contact, but not both at the same time. Even when the two disks are identical, in the end, their centers will translate up and down, and they will counter rotate. The way to make the two disks stop, is if their centers are connected to ground.

This is the challenge: how to control the rotation of multiple discs along the same axis? Assume you have a sliced cylinder. The ideal scenario would be to control every slice independently, but to make things easier I think it helps to consider that you can move them in a fixed number of combinations and on the same direction (e.g. a mechanism ...
