A load P is supported by a structure consisting of rigid bar ABC, two identical solid bronze [E = 16400 ksi] rods, and a solid steel [E = 31500 ksi] rod, as shown. The bronze rods (1) each have a diameter of 0.79 in. and they are symmetrically positioned relative to the center rod (2) and the applied load P. Steel rod (2) has a diameter of 0.49 in. Assume L₁=56 in and L₂=78 in. If all bars are unstressed before the load P is applied, determine the normal stresses in bronze rods (1) and steel rod (2) after a load of P = 34 kips is applied. (1) Answers: 0₁ = 0₂ = L2 (2) B P (1) ksi. ksi. L₁
