Physics - Heat & Thermo Question with Solution | TestHub

A thin steel ring of inner diameter 40 cm and cross-sectional area $1{\mathrm{mm}}^2$, is heated until is easily slides on a rigid cylinder of diameter 40.05 cm. [for steel, $\alpha =10^{-5}/{}^{\circ }\mathrm{C},\mathrm{Y}=200\mathrm{GPa}$ ] when the ring cools down, the tension in the ring will be
