An elastic bar of length L, uniform cross sectional area A, coefficient of thermal expansion
a, and Young’s modulus E is fixed at the two ends. The temperature of the bar is increased
by T, resulting in an axial stress $$\sigma$$. Keeping all other parameters unchanged, if the length of
the bar is doubled, the axial stress would be
