A welded bimetallic strip (Fig. P5.31) is initially straight. A temperature increment causes the element to curve. The coefficients of thermal expansion of the constituent metals are and Assuming elastic deformation and determine (a) the radius of curvature to which the strip bends, (b) the maximum stress occurring at the interface, and (c) the temperature increase that would result in the simultaneous yielding of both elements.
