Example #$6-$ Poisson Ratio

Problem: Consider the alloy rod, as shown in Fig. $6\mathrm{.}15$ to the right, that is being compressed. Take $E=69[$GPa$]$ and $G=24[$GPa$].$ Change in diameter: $1\mathrm{.}36[\backslash$mu m$]$ What is the change in length of the member in Example #$6?$ Units are taken as $[\backslash$mu m$]$; do not report units in your answer. The use of significant digits is not required. Report your answer to the tenths place.
