What would wobble more easily... a thin hoop or a solid disk of the same mass? A solid disk will have a lower moment of inertia, but I'm not sure how this applies to wobbling.
I was just thinking about CD players and how they vibrate a lot from the discs wobbling. Would thickening the outer portion of the disc reduce wobbling by raising the inertia, or would wobbling be reduced by thinning the outer portion of the disc and lowering the inertia?
