A thin horizontal beam XY is freely hinged at point Y to a vertical wall. The beam is held stationary by a cable XZ which is attached to the wall at point Z. The beam supports a weight W at point X. The forces in the cable and the beam are F_C and F_B respectively. Which vector triangle represents the forces acting on point X?
