Two thin metal strips, one of brass and the other of iron are fastened together parallel to each other. Thickness of each strip is 1 mm. If the strips are of equal length at 0^(@)C . The radius of the are formed by the bimetallic strip when heated to 80^(@)C is (Coefficient of linear expansion of brass = 19xx10^(-6)//""^(@)C & of iron = 12xx10^(-6)//""^(@)C ).

A bimetallic strip is formed out of two identical strips, one of copper and the other of brass. The coefficients of linear expansion of the two metals are alpha_(c) and alpha_(B) . On heating, the temperature of strip increases by DeltaT and the strip bends to form an arc of radius R. Then R is proportional to

Two equal, straight strips of two different metals are fastened together parallel to each other, a small fired distance d apart to form a bimetallic strip. Find the radius of curvature of the bimetallic strip when it is heated from 0^(@)C" to "t^(@)C .
