Bars (1) are made of steel [E = 30,000 ksi], and bar (2) is made of an aluminum alloy [E = 10,000 ksi]. All bars have cross-sectional areas of A = 3.25 in.² and are unstressed when P is zero. When load P is applied, the strain in bar (2) is found to be 1600x10-6 in./in. Determine the normal stress in bars (1). Use dimensions a = 13 ft and b = 20 ft.
