Solve the problem seen below.

$10-50.$ The steel shaft has a radius of $15$ mm $.$ Determine the torque $T$ in the shaft if the two strain gauges, attached to the surface of the shaft, report strains of $lo{n}_{x^{\text{'}}}=-80({10}^{-6})$ and $lo{n}_{y^{\text{'}}}=80({10}^{-6}).$ Also, compute the strains acting in the $x$ and $y$ directions. $E_{st}=200$GPa,
