When a metal rod is heated it expands because

When a liquid is heated, it expands and its level:

STATEMENT - 1 : A metallic rod is clamped between two fixed support. The rod is heated but not allowed to bend. Tensile stress is developed in it. STATEMENT - 2 : A metallic rod is fixed between two rigid supports. The rod is heated. The strain produced in the rod is ZERO because there is no change in length STATEMENT - 3 : The practical value of Poisson's ratio lies between 0 and 0.5.

Define stress developed in an elastic material.

STATEMENT - 1 : When a rod lying freely is heated, no thermal stress is developed in it. and STATEMENT - 2 : On heating, the length of the rod increase.
