A circular rod of length ‘L’ and area of cross-section ‘A’ has a modulus of elasticity ‘E’ and coefficient of thermal expansion ‘α’. One end of the rod is fixed and other end is free. If the temperature of the rod is increased by ∆T, then
A
stress developed in the rod is E α ∆T and strain developed in the rod is α ∆T
B
both stress and strain developed in the rod are zero
C
stress developed in the rod is zero and strain developed in the rod is α ∆T
D
stress developed in the rod is E α ∆T and strain developed in the rod is zero

Correct : c
