8. A thin uniform rod AB of mass 3m and length 2a is free to rotate in a vertical plane about a smooth horizontal axis through a point P on the rod, where AP = a. The rod is released from rest when PB 3 makes an angle ß with the horizontal. (a) Show that in the ensuing motion, 19a dt 249(sin 0 – sin B), where 0 is the angle the rod makes with the horizontal at time t. (b) When B = 0, find the magnitude of the reaction on the axis of rotation when e %3D
