A linearly strain-hardening material with a true-stress-true-strain curve given by σ = 34.5 + 172.4 ε is being drawn into a wire. If the original diameter of the wire is 0.635 cm, what is
the minimum possible diameter at the exit of the die? Assume that there is no redundant work and that frictional work is 15% of the ideal work of deformation. (Hint: the yield stress of the exiting wire is the point on the true-stress-true-strain curve that corresponds to the total strain the material has undergone).
