A steel tube has an outside diameter $d_2=50mm,$ shear modulus of elasticity $G=27$ GPa and a Poisson's ratio of $0\mathrm{.}33.$ The tube is subjected to a pure shear condition as a result of an applied torque $T=4\mathrm{.}0kNm.$ The allowable shear stress for the steel is $50$ MPa and the allowable normal strain is $900{10}^{-6}.$ Determine the expression for the maximum normal strain? Ensure your solution is fully simplified.
