Mass moments

  1. Apr 1, 2007 #1
    1. The problem statement, all variables and given/known data
    See attached!


    2. Relevant equations
    See work...A little long to type here.

    3. The attempt at a solution

    You can see my work - and I can't figure out how to get the answers I wrote. I know the idea of Ic = Ia + Ib and whatnot, and how for these thin plates, you can say that Imass = (rho)(t)(Iarea), but I just cannot get the answer. Help please?



    Thanks in advance for any direction!
