1. The problem statement, all variables and given/known data In the image attached, I'm asked to find the mass moment of inertia about an axis at point O that's perpendicular to the page. 3. The attempt at a solution The only question about this problem that I have is: Can I divide the composite body at point O and find the moments of inertia of each part separately, applying the parallel axis theorem for the disk and the vertical rod, then adding all of them up? Thanks!
