Assume uniform elongation, no friction, no distortion. Given that the initial diameter is 0.75 inch, please calculate: (1) The true strain at the end of deformation, ɛ. (2) The average flow stress during this deformation, Y (3) The ideal work per unit volume required for this deformation, Ui. (4) If the efficiency is 70%, the pressure required to accomplish this deformation.
