1.2 m A 0.9 m B 0.9 m D P Figure 1 The structure shown in Figure 1 is used to suspend heavy items. The structure is composed by four main members: The cable holding the load P, the pulley C, the beam ABC, and the solid, circular, A-36 steel¹ link DB. The structure is assembled using four 40 mm diameter A-36 steel pins (i.e. A, B, C and D) that work in single shear. The cable has a breaking load of 100 kN and the link BD has a diameter of 50 mm. It has already been established that the beam ABC can safely resist a load P = 150 kN. By analyzing all remaining possible failure modes you are required to establish the safe working load Pswl for this structure. Neglect the self-weight and use a F.S. = 2 in the calculation of all structural members.
