A pipe that is twist$-$restrained at both ends has an inside radius $r_i=12mm$ and an outside radius $r_0=17mm.$ 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 $=0\mathrm{.}0004$rad. If the pipe is $1\mathrm{.}18m.$ long and has a shear modulus $G=91$ 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.
