Homework Help: Calculate Moment of inertia

  1. Aug 6, 2007 #1
    I am trying to find out how to calculate the
    mass moment of inertia of an assembly.
    I have basically a ring 7 inch ID,11 Inch OD
    and 1 inch thick.

    On this ring I have several rectangular boxes mounted
    of various sizes around its periphery (screwed.)
    This ring will rotate about its axis along with those
    boxes of different sizes.
    How do I calculate the inertia of the assembly?

    please help.

    This is a HW/Schoolwork-type question. So it belongs in the HW/Coursework forum even if it isn't a homework assignment.
