Question

11. (14 points) A 1000 N sign mounted on the side of a building is suspended from a horizontal rigid rod 1.5 m long, which is supported at one end by the building, and at the other by a steel cable which makes an angle of 40° with the horizontal. The sign is hung from the rod at a point 1 m from the wall. The end attached to the wall is free to pivot. If the weight of the rod and the weight of the cable are neglected, Calculate a) the force exerted on the rod by the wall. b) the force in the cable.
