Only Solve for Part A$.$

During a tensile test in which the starting gage length $=100\mathrm{.}0$ mm and the cross$-$sectional

area $=150$ mm$2.$ During testing, the following force and gage length data are collected: $(1)17,790$ N

at $100\mathrm{.}2$ mm$,(2)23,040$ N at $103\mathrm{.}5$ mm$,(3)27,370$ N at $110\mathrm{.}5$ mm$,(4)30,910$ N at $122\mathrm{.}0$ mm$,(5)$

$27,400$ N at $130\mathrm{.}0$ mm$,$ and $(6)20,460$ N at $135\mathrm{.}1$ mm$.$ The final data point $(6)$ occurred immediately

prior to failure. Yielding occurred at a load of $19,390$ N $(0\mathrm{.}2\%$ offset value$),$ and the maximum load

occurred at point $4.($a$)$ Plot the engineering and true stress$-$strain on the same plot based on the
