Two mettalic strips each of length l_(0) and thickness d, temperature T_(0) are riveted together so that their ends coincide. One strip is maxe of a metal of coeficient of expansioin alpha_(1) and the other of a metal with a coefficient alpha_(2), where alpha_(2)gtalpha_(1). When this bimetallic strip is heated to a temperature T_(0)+DeltaT, find the radius of curvature R of the strip.

1.	Two mettalic strips each of length l_(0) and thickness d, temperature T_(0) are riveted together so that their ends coincide. One strip is maxe of a metal of coeficient of expansioin alpha_(1) and the other of a metal with a coefficient alpha_(2), where alpha_(2)gtalpha_(1). When this bimetallic strip is heated to a temperature T_(0)+DeltaT, find the radius of curvature R of the strip.
