Assume that r$\_($i$)=0\mathrm{.}071$m$,$r$\_(0)=0\mathrm{.}072$m$,\backslash$mu $=1\mathrm{.}49$k$($g$)/($m$)-$s $($glycerin$),\backslash$rho $=1260$k$($g$)/($m$)3,$ and $\backslash$Omega $\_($i$)=120$re$($v$)/($m$)$in$=12\mathrm{.}57$ra$($d$)/($s$)$ with

the inner cylinder rotating and outer cylinder fixed.

Calculate the inner shear stress for the given flow.

The inner shear stress is
