Making a rope follow a cam?

Working with a compound bow and I would like to model the motion profile as the wire rope gets pulled and rotates the cam. (In real life it does move the cam pivot position due to the limbs flexing, but I'm trying to figure out the motion problem first.) The animation will let me move the lower donut and "pulls" on the string as it has a static dimension. The problem is that it doesn't rotate the cam as it pulls through the cam instead of stopping when rope and cam touch. The motion analysis doesn't move at all, so I'm not sure what to try next.
