Before the 400-kN load is applied, the rigid platform rests on two steel bars, each of cross-sectional area 1400 mm?, as shown in the figure. The cross-sectional area of the aluminum bar is 2800 mm?. Compute the stress in the aluminum bar after the 400-kN load is applied. Use E = 200 GPa for steel and E = 70 GPa for aluminum. Neglect the weight of the platform
