engineering recuitment UPSSSC JE Civil 2024 Mock Test Strength of Materials Simple Stress and Strain Axial Elongation of Bar
U1 and U2 are the strain energies stored in a prismatic bar due to tensile forces P1 and P2 respectively. The strain energy stored in the same bar due to combined action P1 and P2 will be
1
U = U1 + U2
2
U = U1 × U2
3
U < U1 + U2
4
U > U1 + U2
