A shop sign weighing 75 N hangs from a frame attached to a vertical wall. The frame consists of a horizontal rod XY and a rod YZ that is at an angle of 30° to the horizontal. Rod XY is attached to the wall by a hinge at X and has length 0.50 m. Assume that the weights of the rods are negligible. What is the horizontal force exerted by the wall on rod XY?
