1. The problem statement, all variables and given/known data A curcial part of a piece of machinery starts as a flat uniform cylindrical disk of radius R0 and mass M. It then has a circular hole of radius R1 drilled into it. The hole's center is a distance h from the center of the disk. Find the moment of inertia of this disk (with off-center hole) when rotated about its center, C. Hint: Consider a solid disk and subtract the hole; use parallel-axis theorem. 2. Relevant equations L=IA 3. The attempt at a solution I spent hours on paper with no end, google "chicken scratch" for proof.
