A FCC single crystal is mis$-$oriented, for its $(111)[101]$ slip system, the angle between the tensile axis $[001]$ and the normal of the slip plane has been decreased by $24\mathrm{.}74$ degree and the angle between the slip direction and the tensile axis $[001]$ has been increased by $15$ degree. If this sample is pull along the $[001],$ and the critical resolved shear stress is $5$MPa for the above slip system, please determine the minimum tensile stress requirement to cause yielding:
