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 forces P, and P the strain energies stored in the bar are U, and U respectively 1 T P (P, + P) If U is the strain energy stored in the same bar when subjected to an axial tensile force (P, + P2), the correct relationship is (a) U = U, - U, (c) U > U, + U, (b) U< U, + U2 (d) U = U, + U,
