Question

Consider the figure above consisting of three particles of mass m attached to a massless rod. Given an axis of rotation through point P, the rod rotates as shown in the figure. If the rod is released from rest in the horizontal position at t = 0. What is the angular acceleration of the system (rod and three particles) immediately after being released? Let d = 2.50 m. m1---m2-P--m3 The distance between P and m3 is (2d/3. The distance between m1 and m2 is the same and distance between m2 and m3 are the same.
