A metal rof having coefficient of linear expansion alpha and Young's modulus Y is heated to raise its temperature by Delta theta . The stress exerted by the rod is

A metal rod having coefficient of linear expansion (alpha) and Young's modulus (Y) is heated to raise the temperature by Delta theta . The stress exerted by the rod

A metal rod is fixed rigidly at two ends so as to prevent its thermal expansion. If L, alpha and Y respectively denote the length of the rod, coefficient of linear thermal expansion and Young's modulus of its material, then for an increase in temperature of the rod by DeltaT , the longitudinal stress developed in the rod is
