Consider the diagram below in which of solid rod of length

L is rotating by a massless string about the center of a circle. (a)

Starting with the center of mass inertia for a simple rod derive an

expression for the inertia of the system shown below. (b) Show that

this inertia reduces to that of a rod rotating about one axis, (what is the

nessesary condition to make this happen?). (c) Using your exprssion

from part (a) show that the minimum inertia is
