A load Pis supported by a structure consisting of rigid bar ABC, two identical solid bronze [E = 17700 ksi] rods, and a solid steel [E = 27500 ksi] rod, as shown. The bronze rods (1) each have a diameter of 0.78 in. and they are symmetrically positioned relative to the center rod (2) and the applied load P. Steel rod (2) has a diameter of 0.51 in. Assume L1=39 in and L2=63 in. If all bars are unstressed before the load Pis applied, determine the normal stresses in bronze rods (1) and steel rod (2) after a load of P = 34 kips is applied.
