1. In Figure 6.23, estimate the UTS for each metal. Also, identify the material with the largest ductility. 2. A 0.505-in.-diameter aluminum alloy test bar is subjected to a load of 25,000 lb. If the diameter of the bar is 0.490 in. at this load, determine (a) the engineering stress and strain and (b) the true stress and strain.
