Homework Help: Moment of Inertia and Center of Mass for Point Particles

  1. Nov 5, 2005 #1
    I am having difficulty solving the first part of this problem. I have tried to many ways to find the ratio of m_a/m_b but I can't seem to get the correct answer. Can someone point me in the right direction. Thanks.

    Could you show the methods you've tried?

    I think there's a mistake in the pdf you provided:
    Ia = maL2
    Should be:
    Ia = mbL2 (mass a's distance from axis a is 0).
