d₁ A Brass B Aluminum L₁ The two rods below are constrained between two rigid walls. AB is brass (E = 105 GPa, ab = 20.9 x 10-6 m/(m.°C)) and BC is aluminum (EAI = 72 GPa, a Al = 23.9 x 10-6 m/(m-°C)). At T₁ = 18.5°C, there is no stress in the rods. Determine the stress in the brass rod AB at T₂ = 65.6°C. Use the following dimensions: d₁ = 52 mm d₂ = 45 mm L₁ = 1.93 m L₂ = 1.67 m Calculate your answer to one decimal place. and use a '-', if necessary. Report your answer in MPa Hint: Assume all deformation is elastic.
