A load of P = 88 kN is supported by a structure consisting of rigid bar ABC, two identical solid bronze [E = 80 GPa] rods, and a solid steel [E = 167 GPa] rod, as shown. The bronze rods (1) each have a diameter of 19 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 1.8-mm clearance in the bolted connection at B. Assume L₁= 3.5 m and L₂ = 1.6 m. Determine: (a) the normal stresses in the bronze and steel rods (01, 02). (b) the downward deflection v of rigid bar ABC. (1) L2 (2) B (1) L₁
