PLS ANSWER URGENT, THANK YOU.

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.
