1.	Two rods of thickness d and of length l are riveted. If the temperature is increased by theta, what will be the average radius of curvature of the combination? Coefficient of linear expansion of the materials of the two rods are alpha_(1) " and " alpha_(2).
Answer» ANSWER :`(d[2+(alpha_(1)+alpha_(2))THETA])/((alpha_(1)-alpha_(2))theta)`
