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 R=(s)/((α2-α1) ΔT) [Hint: At T0, the lengths of the two layers are the same. At temperature T0 ΔT, the layers form circular arcs of radii R and R s, which subtend the same angle θAssume a small ΔT so that αΔT ≪1 (for eith
