1. The problem statement, all variables and given/known data Need to find the moment of inertia of a cylinder, about its center of mass, about the three principle axes. Z axis is normal to the circular faces of the cylinder. mass = M, radius = R, height = h 2. Relevant equations ∑miri2 3. The attempt at a solution The Izz for whatever reason is trivial for me, easy to solve. The Iyy = Ixx I'm having trouble with. I think it might be because this requires a double integral?
