A slender horizontal beam XY is attached by a free hinge at point Y to a vertical wall. The beam is kept in equilibrium by a cable XZ fixed to the wall at point Z. A weight $W$ acts on the beam at point X. The force in the cable is $F_C$, and the force in the beam is $F_B$ respectively. Which vector triangle shows the forces on point X?
