At left, two identical square plates both of which have mass = m, side length = L and O L center of mass (cm) at their center are connected together by a thin rigid rod (mass = m ; length = L). It is desired that the plates/rod system rotate in the plane of the page about an axis through point (P) which is at the center of mass of the rod. a. What is the moment of inertia of either square plate for an axis through its cm? b. What is the moment of inertia of either square plate for an axis through point (P)? c. What is the moment of inertia of the system (both plates and the rod) for the axis through point (P)
