A uniform thin wire of mass M is bent into the form of a square OPQR of side 2a. Show that the moment of inertia of the wire about an axis through O perpendicular to the plane of the square is 10Ma2/3 . The wire frame can rotate freely in the vertical plane about a smooth pivot at O. It is held with P vertically above O and is released from rest. Find the initial acceleration of the point P. Find also the force exerted by the pivot at the instant when OQ is vertical.
