The lower ends of the three bars shown are at the same level before the uniform rigid block weighing 32 kips is attached. Each steel bar has a length of 5 ft, and area of 1.6 in.2, and E = 30 x 106 psi. For the bronze bar, the area is 1.2 in.? and E 13 x 106 psi. Determine the length (in feet) of the bronze bar so that the load on each steel bar is twice the load on the bronze bar.
