A bimetallic strip with thickness x is originally straight at temperature T. When it is heated to temperature T + AT, it bends and forms a curve with radius of curvature R. Given the coefficients of linear expansion of the two metals are a, and a2, respectively, with a2 > a1, Find R. Assume that the two metals have equal thickness and R » x.
