A load P is supported by a structure consisting of rigid bar ABC, two identical solid bronze [E = 15,000 ksi] rods, and a solid steel [E = 30,000 ksi] rod. The bronze rods (1) each have a diameter of 0.75 in. and they are symmetrically positioned relative to the center rod (2) and the applied load P. Steel rod (2) has a diameter of 0.50 in. The normal stress in the bronze rods must be limited to 14 ksi, and the normal stress in the steel rod must be limited to 18 ksi. Determine: (a) the maximum downward load P that may be applied to the rigid bar. (b) the deflection of the rigid bar at the load determined in part (a). (1) A 90 in. (2) B (1) C 50 in.
