The mechanism shown is used to lower handicapped persons into a whirlpool tub for therapeutic treatment. In the unloaded configuration, the weight of the boom and hanging chair induces a compressive force of 695 N in hydraulic cylinder AB. (Compressive means that the force which cylinder AB exerts on point B is directed from A towards B.) If 0 = 20°, determine the moment made by this cylinder force which acts on point B about (a) point O and (b) point C. The moments are positive if counterclockwise, negative if clockwise.

A load P is supported by a structure consisting of rigid bar ABC, two identical solid aluminum alloy [E = 73 GPa] rods (1), and a solid bronze [E = 105 GPa] rod (2). The aluminum rods (1) each have a diameter of 8 mm and a length of L₁ = 1.5 m. They are symmetrically positioned relative to middle rod (2) and the applied load P. Bronze rod (2) has a diameter of 16 mm and a length of L₂ = 1.0 m. If all bars are unstressed before the load P is applied, determine the normal stresses in the aluminum and bronze rods after a load of P = 66 KN is applied to the rigid bar.
