Required information

A P$=2-$kN tensile load is applied to a test coupon made from $1\mathrm{.}6-$mm thick flat steel plate $(E=190$GPa,$v=0\mathrm{.}30).$ Assuming $a=60mm$ and $b=11mm,$

$($a$)$ Determine the resulting change in the $60-mm$ gage length.

$($b$)$ Determine the resulting change in the $11-mm$ width.

$($c$)$ Determine the resulting change in the $1\mathrm{.}6-mm$ thickness.

$($d$)$ Determine the resulting change in the cross$-$sectional area.
