Question- A prismatic linearly elastic bar of length, L, cross sectional area A, and made up of a material with Young's modulus E, is subjected to axial tensile force as shown in the figures. When the bar is subjected to axial tensile force P1 and P2 the strain energies stored in the bar are U1 and U2 respectively. 1. 1. P_{1} 1. 1. P_{2} 1. 1. (P_{1} + P_{2}) 1. 1. If U is the strain energy stored in the same bar when subjected to an axial tensile force (P1 + P2) . the correct relationship is 1. 1. (a) U = U1 - U2 (c) U < U1 + U2 1. 1. (b) U = U1 + U2 1. 1. (d) U > U1 + U2 1. 1. [GATE 2020: 2 Marks, Set-II]
