(10%) Problem 8: A uniform beam of length L = 1.5 m and mass M = 11 kg has its lower end xed to pivot at a point P on the oor, making an angle 6 = 13 as shown in the diagram, 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. R 33% Part (a) What is the y-component Py of the force, in newtons, exerted by the pivot on the beam? 33% Part (b) Write an expression for the tension T in the horizontal cable AB.
