A uniform beam of length L = 1.1 m and mass M = 29 kg has its lower end fixed to pivot at a point P on the floor, making an angle θ = 11° 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.

A uniform beam of length L = 2.3 m and mass M = 44 kg has its lower end fixed to pivot at a point P on the floor, making an angle θ = 11° 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. Part (a) What is the y-component Py of the force, in newtons, exerted by the pivot on the beam? Part (b) Write an expression for the tension T in the horizontal cable AB. Part (c) What is the x-component Px of the force, in newtons, exerted by the pivot on the beam?

A uniform beam of length L = 1.5 m and mass M = 38 kg has its lower end fixed to pivot at a point P on the floor, making an angle ̘ = 27° 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. What is the y-component Py of the force, in newtons, exerted by the pivot on the beam? Write an expression for the tension T in the horizontal cable AB. What is the x-component Px of the force, in newtons, exerted by the pivot on the beam? Draw the torque diagram.
