Mass Moment of Inertia of a Composite Body

  1. Apr 14, 2013 #1
    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?
