For some metal alloy, a true stress of 345 MPa (50040 psi) produces a plastic true strain of O.02. How much will a specimen of this material elongate when a true stress of 411 MPa (59610 psi) is applied if the original length is 450 mm (17.72 in.)? Assume a value of 0.22 for the strain-hardening exponent, n. mm
