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 (EAI = 72 GPa, aAl = 23.9 x 10-6 m/(m·°C)). At T₁ = 13.1°C, there is no stress in the rods. Determine the stress in the brass rod AB at T₂ = 56.2°C. Use the following dimensions: d₁ = 67 mm d₂ = 27 mm L₁ = 1.05 m L₂ = 1.91 m Calculate your answer to one decimal place, and use a '-', if necessary. Report your answer in MPa Hint: Assume all deformation is elastic.
