Question:

A bimetallic strip is made from metals with expansion coefficients α₁ and α₂ (with α₂ > α₁). The thickness of each layer is s. At some temperature T0, the bimetallic strip is relaxed and straight.

(a) Show that, at temperature T₀ + ΔT, the radius of curvature of the strip is

(b) If the layers are made of iron and brass, with s = 0.1 mm, what is R for ΔT = 20.0°C?
