MJ20 P13 Q14 Force on Slanted Rod | May/June 2020 | CAIE A Level 9702 Physics

9702/13/M/J/20: A light rigid rod XY has an object of weight W fixed at one end. The rod is in equilibrium, resting on a support at Z and a vertical wall at X. The support exerts a force R on the rod as shown. The diagram shows the directions, but not the magnitudes, of the forces R and W.
What is the direction of the force on the rod at X?

Another way to think of it is by looking at the lines of action. Because anti-parallel forces in equilibrium must have a line of action passing through the same point. If we extend each force drawn, then we will see that only D meets at the same point as the other forces.

Yes, good method with drawing the lines of action!

Amazing explanation!!
