A load of P = 88 kN is supported by a structure consisting of rigid bar ABC, two identical solid bronze [E = 113 GPa] rods, and a solid steel [E = 179 GPa] rod, as shown. The bronze rods (1) each have a diameter of 20 mm and they are symmetrically positioned relative to the center rod (2) and the applied load P. Steel rod (2) has a diameter of 29 mm. All bars are unstressed before the load P is applied; however, there is a 1.7-mm clearance in the bolted connection at B. Assume L₁= 2.9 m and L₂= 1.5 m. Determine: (a) the normal stresses in the bronze and steel
