A uniform beam of length L and mass M has its lower end pivoted at P on the floor, making an angle θ with the floor. A horizontal cable is attached at its upper end B to a point A on a wall. A box of mass M is suspended from a rope that is attached to the beam one-fourth L from its upper end.- 25% Part (a) Write an expression for the y-component Py of the force exerted by the pivot on the beam.Py = - 25% Part (b) Write an expression for the tension T in the horizontal cable ABT = |- 25% Part (c) Write an expression for the x-component Px of the force exerted by the pivot on the beam, in terms of T. Px = |- 25% Part (d) What is the tension in the horizontal cable, in newtons, if the mass of the beam is 48 kg, the length of the beam is 8 m, and the angle is 36°?T = |
