: , a material-specific constant. L0cap L sub 0 : Original (initial) length. ΔTcap delta cap T : Change in temperature ( Practice Problems and Step-by-Step Solutions 1. Calculating Expansion in Infrastructure Problem : The main span of a steel bridge is

ΔT = 30°C Strain if free = α ΔT = (2.3e-5)(30) = 6.9e-4 But walls prevent expansion → compressive stress: Stress = Y × (α ΔT) = (7.0e10)(6.9e-4) = 4.83 × 10⁷ Pa linear thermal expansion problems and solutions pdf
