Homework Help: Period of oscillation of a rocking semi cylinder?

  1. Feb 4, 2009 #1
    1. The problem statement, all variables and given/known data
    a thin rectangular plate is bent into a semicircular cylinder, dertermine the period of oscillation if it is allowed to rock on a horizantal surface.

    3. The attempt at a solution

    So I can figure out the rest of the problem if I know what the moment of inertia of a half cylinder is. My side note is a guess, but not sure if it is correct. I checked around online couldn't find anything that helpful
