Homework Help: Periodic Motion

  1. Mar 23, 2008 #1
    1. The problem statement, all variables and given/known data

    A metal plate in the shape shown has a mass of 2.00kg and hangs from a pivot point located a distance d=0.300m from its center of mass. Its moment of inertia, I_cm, about an axis perpendicular to the plate and passing through the CM is 0.210kg*m2. Calculate the magnitude of the angular acceleration of the plate when theta=0.210 rad.

    2. Relevant equations

    3. The attempt at a solution

    I'm really not sure where to start. Does anyone have some insight or a guiding principle?
