Question 1 5 pts 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, αAI = 23.9 x 10-6 m/(m-°C)). At T₁ = 12.3°C, there is no stress in the rods. Determine the stress in the brass rod AB at T₂ = 54.2°C. Use the following dimensions: d₁ = 70 mm d₂ = 35 mm L₁ = 1.09 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. d₁ + d₂
