Historically, small gaps were left between rails to prevent them from "sun kinking" on hot days. Bimetallic Strips: By joining two metals with different A steel bridge is 500 meters long

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 We will explore the theory behind linear expansion,

The final length is then: [ L = L_0 (1 + \alpha \Delta T) ]

A glass flask (α_glass = 9 × 10⁻⁶ /°C) has a 10.00 cm long scale etched on its neck. If filled with mercury at 20°C, the mercury rises to the 10 cm mark. When heated to 80°C, the mercury rises to 10.35 cm. Find the α of mercury?
