Two metaliic strips of different metals ...

Two metaliic strips of different metals are riveted together to form a composite metallic strip of thickness 0.1 cm. If the strip is heated to `100^(@)C`, what will be the radius of curvature of the strip? Given, the values of `alpha` of the two metals are `18 times 10^(-6@)C^(-1) " and " 12 times 10^(-6@)C^(-1)`.
