Question Description
An elastic bar of length L, uniform cross sectional area A, coefficient of thermal expansion α, 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 σ. Keeping all other parameters unchanged, if the length of the bar is doubled, the axial stress would be a)σ b)2 σc)0.5 σd)0.25 α σCorrect answer is option 'A'.
