d₁ A Brass B Aluminum L₁ L₂ The two rods below are constrained between two rigid walls. AB is brass (E₁ = 105 GPa, ab = 20.9 x 10-6 m/(m-°C)) and BC is aluminum (EA₁ = 72 GPa, aAl = 23.9 x 10-6 m/(m.°C)). At T₁ = 18.6°C, there is no stress in the rods. Determine the stress in the brass rod AB at T₂ = 65.1°C. Use the following dimensions: d₁ = 65 mm d₂ = 48 mm L₁ = 1.01 m L₂ = 1.04 m Calculate your answer to one decimal place, and use a '-', if necessary. Report your answer in MPa Hint: Assume all deformation is elastic. d₂
