The maximum amount of strain energy per unit volume that can be stored in this speciment without permanent set, is-A-156 Nmm/mm3B-15.6 Nmm/mm3C-1.56 Nmm/mm3D-0.156 Nmm/mm3-D-0.156 Nmm/mm3

Question

A mild steel specimen is under uni-axial tensile stress. Young&#39;s modulus and yield stress for mild steel are 2 x 105 MPa and 250 MPa respectively. The maximum amount of strain energy per unit volume that can be stored in this speciment without permanent set, is-A-156 Nmm/mm3B-15.6 Nmm/mm3C-1.56 Nmm/mm3D-0.156 Nmm/mm3-D-0.156 Nmm/mm3

APTITUDE CRACK · Accepted Answer

D 0.156 Nmm/mm3 P^2/ 2E = (250^2)/(2*2*10^5) = 0.156.
