Note that there is some overlap in the data.

$($a$)$ Plot the engineering or nominal stress$-$strain diagram using two scales for the unit strain $,$ one scale from zero to about $0\mathrm{.}02i\frac{n}{i}n$ and the other scale from zero to maximum strain.

$($b$)$ From this diagram find the modulus of elasticity, the $0\mathrm{.}2$ percent offset yield strength, the ultimate strength, and the percent reduction in area.

$($c$)$ Characterize the material as ductile or brittle. Explain your reasoning.

$($d$)$ Identify a material specification from Table A$-20$ that has a reasonable match to the d
