Problem 2: A uniform beam of length L= 1.9 m and mass M = 49 kg has its lower end fixed to pivot at a point P on the floor, making an angle 0 = 15° as shown in the digram. A horizontal cable is attached at its upper end B to a point A on a wall. A box of the same mass M as the beam is suspended from a rope that is attached to the beam one-fourth L from its upper end. M M.
