The rigid beam is supported by a pin at A and two steel wires, each having a diameter of 4 mm. If the yield stress for the wires is σY = 530 MPa, and Est = 200 GPa, determine (a) the intensity of the distributed load w that can be placed on the beam that will cause only one of the wires to start to yield and (b) the smallest 'intensity of the distributed load that will cause both wires to yield. For the calculation, assume that the steel is elastic perfectly plastic.
