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
A
$$\sigma$$
B
$$2\sigma$$
C
$$0.5\sigma$$
D
$$0.25\sigma$$
