Question

A tension test is being conducted on a steel-rod specimen with a gauge length of L0=50mm and initial diameter of d0=13mm. Data were collected to form the conventional stress-strain diagram as shown. From the diagram, f = 510 MPa , e = 693 MPa , g = 565 MPa , and ℎ = 0.15 mm/mm

Assuming that the strain remains constant throughout the region between the gauge points, determine the nominal strain ε experienced by the rod if it is elongated to L = 65.0 mm.
