A specimen of material A in a tension test elongates from an original length of 2.2 to a length L uniformly, after which is necking begins. The strength coefficient of the material is given as 120,000 psi, and the strain hardening exponent is 0.5. Determine the UTS and true ultimate stress of the material, and the length L. The material reaches plastic deformation at a third of the distance from the original gauge length to L. Calculate the true yield strain and true yield stress.
