Question: A stress strain plot is shown for a 1 6 0 mm long specimen. Note the lower scale is just a 1 0 factor magnification

A stress strain plot is shown for a 160 mm long specimen. Note the lower scale is just a 10 factor magnification of the initial part of the upper scale. Identify the elastic modulus and the yield stress (by the offset method above). Also identify the ultimate strength. Finally if the specimen is loaded to 1000 MPa and then unloaded determine its new length.
