Problem\#4: The stress-strain diagram for a tension test of an alloy specimen is plotted and the following data are recorded: Initial diameter $=13\mathrm{mm}$ Gage Length $=50\mathrm{mm}$ Diameter at the fractured section $=11\mathrm{mm}$ Final length after fracture $=66\mathrm{mm}$ Stress at proportional limit $=276\mathrm{N}/{\mathrm{mm}}^2$ Strain at proportional limit $=0.002$ Determine (a) the modulus of elasticity (b) the percent elongation, and (e) the percent reduction in area.
