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. [Figure showing two beams XY and YZ hinged at Y, supporting a weight of 4.0 × 10⁴ N, with 50° angles to the horizontal]
