H.W.21 A load of P = 100 kN is supported by a structure consist- ing of rigid bar ABC, two identical solid bronze [E = 100 GPa] rods, and a solid steel [E = 200 GPa] rod as shown in Figure Each of the bronze rods (1) has a diameter of 20 mm and is symmetrically positioned relative to the center rod (2) and the applied load P. Steel rod (2) has a diameter of 24 mm. All bars are unstressed before the load P is applied; however, there is a 3-mm clearance in the bolted connection at B. Determine (a) the normal stresses in the bronze and steel rods. (b) the downward deflection of rigid bar ABC. (1) (1) 3.0 m 1.5 m B
