A metal rod if fixed rigidly at two ends so as to prevent its hermalexpension. If L,`alpha` Y respectively denote the length of the rod , coefficeent of linear thermal expension and Young's modulus of its material, then for an increase in temperature of the rod by `Delts`T, the longitudinal stress developed in the rod is
