Question

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, as shown. The bronze rods (1) each have a diameter of 0.500 in. and they are symmetrically positioned relative to the center rod (2) and the applied load P. Steel rod (2) has a diameter of 0.360 in. If all bars are unstressed before the load P is applied, determine the normal force in steel rod (2) after a load of P = 36 kips is applied.
