A compressive force, F is applied at the two ends of a long thin steel rod. It is heated, simultaneously, such that its temperature increased by ΔT. The net change in its length is zero. Let L be the length of the rod, A is its area of cross-section. E is Young's Modulus, and α is its co-efficient of linear expansion. Then, F is equal to
