SSC RSMSSB JE Mock Test 2024 Strength of Materials Simple Stress and Strain Thermal Stress and Strain
A circular rod of length 'L' and area of cross section 'A' has a modulus of elasticity 'E' and co-efficient of thermal expansion 'α'. One end of the rod is fixed and the other end is free. If the temperature of the rod is increased by ΔT, then
1
stress developed in the rod is E × α × ΔT and strain developed in the rod is α × ΔT
2
Both stress and strain developed in the rod are zero
3
stress developed in the rod is zero and strain developed in the rod is α × ΔT
4
stress developed in the rod is E × α × ΔT and strain developed in the rod is zero
