For some metal alloy, a true stress of 345 MPa (50040 psi) produces a plastic true strain of 0.02. How much will a specimen of this material elongate when a true stress of 410 MPa (59470 psi) is applied if the original length is 480 mm (18.90 in.)? Assume a value of0.22 for the strain-hardening exponent, n.
