A liquid of volumetric thermal expansion coefficient = `gamma` and bulk modulus B is filled in a spherical tank of negligible heat expansion coefficient its radius R and wall thickness is t `(tleleR)` when the temperature of the liquid is raised by theta the tensile stress developed in the walls of th tank is:

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
