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 = 1.75 in.² and are unstressed when P is zero. When load P is applied, the strain in bar (2) is found to be 1700x10-6 in./in. Determine the normal stress in bars (1). Use dimensions a = 16 ft and b = 23 ft. a a Answer: 01 = i A B b (1) (1) ksi D
