# Rotational simple harmonic motion: A hanging square frame

Square object of mass {m} is constructed of four identical uniform thin sticks, each of length {L}, attached together. This object is hung on a hook at its upper corner.

If it is rotated slightly to the left and then released, at what frequency will it swing back and forth?

Answer must be expressed in terms of the variables m, L, and appropriate constants.
