A general question on finding the moment of inertia from oscillations.

  1. Nov 21, 2005 #1
    Is there a way to find the moment of inertia of an object that is hung from its center of mass, knowing the radius of the string, the period of the oscillation, and the mass of the object? I've been trying to think of how to do this and I don't even know where to start.

    If the object is hung from its center of mass then you're talking about a pendulum but I think you had some other kind of oscillation in mind?

    The big assumption is that the initial displacement is relatively small,
    i.e. sinθ = θ.
