$2.(14$ pts total$)$ Consider a cylindrical specimen of a steel alloy of $8\mathrm{.}5$ mm in diameter and $80$ mm long that is pulled in tension. Use the engineering stress$-$engineering strain characteristics plotted below to answer the following questions. The inset shows the small strain part of the curve. The Poisson's ratio of this steel alloy is $0\mathrm{.}33.$

$($a$)(6$ pts$)$ Determine the final length of this specimen after the applied load at point A is released.

$($b$)(4$ pts$)$ Determine the Young's modulus and the yield strength of this alloy $($at a strain offset of $0\mathrm{.}002).$

$($c$)(4$ pts$)$ Calculate the true stress and true strain at point B$.$

Please clearly and correctly solve each part, be thorough!
