question_answer
A metal bar of length L and area of cross-section A is clamped between two rigid supports. For the material of the rod, its Young?s modulus is Y and coefficient of linear expansion is \[\alpha \]. If the temperature of the rod is increased by \[\Delta {{t}^{o}}C,\] the force exerted by the rod on the supports is [MP PMT 2001]
