✅ Compare to known values: This is likely aluminum or brass. Question: An aluminum rod (α = 2.3 × 10⁻⁵ /°C, Y = 7.0 × 10¹⁰ Pa) is 1.000 m at 20°C. It is fixed between two rigid walls. If the temperature rises to 50°C, what is the thermal stress?
ΔL = 1.504 – 1.500 = 0.004 m ΔT = 85 – 15 = 70°C α = ΔL / (L₀ ΔT) = 0.004 / (1.500 × 70) = 3.81 × 10⁻⁵ /°C linear thermal expansion problems and solutions pdf
