The stress-strain diagram for a steel alloy having an original diameter of0.5 in. and a gauge length of 2 in. is given in the figure. Deterinine approx-imately:(a) the Modulus of Elasticity for the material(b) the load on the specimen that will canse yielding(c) the ultimate load the specimen will support(d) the Modulus of Resilience(e) the Modulus of ToughnessNote that the lower scale supports the lower curve and the upper scalesupports the upper curve. The lower eurve is the initial portion of the entirestress-strain curve that is picked up by the upper curve. The two eurvestogether represent one complete stress-strain curve.
