a) Explain the thermal stress and thermal strain b) An aluminum alloy bar, fixed at both ends, heated through 20K. Find the stress developed in the bar. Take the modulus of elasticity, and coefficient of linear expansion for the bar material as 80GPa and 24(10-6)/K respectively. a) Explain the thermal stress and thermal strain b) An aluminum alloy bar, fixed at both ends, heated through 20K.
