Physics - Elasticity Question with Solution | TestHub

A liquid of volumetric thermal expansion coefficient $200\times 10^{-6}/{}^{\circ }\mathrm{C}$ and bulk modulus $=1.2\times 10^9\mathrm{Pa}$ is filled in a spherical tank of negligible heat expansion coefficient. Its radius is 25 cm and wall thickness is 2 mm . When the temperature of the liquid is raised by $20^{\circ }\mathrm{C}$, find the tensile stress developed (in MPa ) in the wall of the tank.
