Two rigid steel beams XY and YZ are fixed at their lower ends and are hinged at Y. Each beam is inclined at 50° to the horizontal, as shown. A weight of 4.0 × 10⁴ N hangs from Y. The structure is in equilibrium. What is the force exerted by each beam on the hinge at Y?

1. A2.6 × 10⁴ N
2. B3.1 × 10⁴ N
3. C5.2 × 10⁴ N
4. D6.2 × 10⁴ N
