Determine working stresses for the two alloys that have the stress–strain behaviors shown in Figures 6.12 and 6.22.

Figure 6.12 The stress–strain behavior for the brass specimen discussed in Example Problem 6.3.

Figure 6.22 Tensile stress–strain behavior for an alloy steel.

Problem 6.3

A specimen of copper having a rectangular cross section 15.2 mm × 19.1 mm (0.60 in. × 0.75 in.) is pulled in tension with 44,500 N (10,000 lbf) force, producing only elastic deformation. Calculate the resulting strain.
