- TL;DR Summary
- Cylinders rolling down inclines are a common demo. But how do you model the movement of a sphere rolling within a rolling cylinder?
Cylinders rolling down inclines are a common demo.
But how do you model the movement of a sphere rolling within a rolling cylinder?
I teaching a physics class and this question came up and my dynamics math is a little rusty.
But I haven't found anything like this in any book or online.
There's plenty about stuff rolling down inclines, and balls oscillating back and forth inside hollow stationary cylinders.
But put a ball bearing inside a hollow soup can, and everyone's suddenly stumped.
Discuss. :)
