Very Simple Rotation Inertia of a Thin Rod Problem

  1. Apr 1, 2009 #1
    1. The problem statement, all variables and given/known data
    Calculate the rotational inertia of a meter stick, with mass 0.68 kg, about an axis perpendicular to the stick and located at the 21 cm mark. (Treat the stick as a thin rod.)


    2. Relevant equations
    I = integral of radius squared with respect to mass


    3. The attempt at a solution
    I'm not quite sure how to explain my issue here, but I think all I need is to see this worked out, and then I could probably understand the nature of these problems. Thanks.

    You could use the parallel axis theoram if you know how to find the M.I about the centre of mass of the rod (the centre) :smile:
