Two bars, one composed of aluminum and one of steel, are placed end to end as shown in Figure P11.56. The bars are both initially of length L = 25 cm, and both have a square cross section with h = 2.0 cm. If a compressive force F = 10,000 N is applied to each end, what is the change in length of each bar?
