Bars (1) are made of a polyimide plastic that has an elastic modulus of 3.8 GPa. Bar (2) is a nylon material that has an elastic modulus of 0.9 GPa. Each bar has a cross-sectional area of 1050 mm2. Using L = 395 mm and Δ = 7.3 mm, what magnitude of load P will cause the normal stress in each bar to be the same value? [Answer: P = 67.0 kN]
