A pipe that is twist$-$restrained at both ends has an inside radius ri$=14$ mm and an outside radius ro$=18$ mm$.$ The pipe is subjected to a torque loading along its length in such a way that if the right end is allowed to twist, the angle of twist would be

$=0\mathrm{.}0003$ rad. If the pipe is $1\mathrm{.}33$ m$.$ long and has a shear modulus G$=80$ GPa, what is the torque reaction at the end of the pipe? Express your answer in kN$.$m using zero $(0)$ digits after the decimal point.
