Question: A FCC single crystal is mis - oriented, for its ( 1 1 1 ) [ 1 0 1 ] slip system, the angle between

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 24.74 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 5MPa for the above slip system, please determine the minimum tensile stress requirement to cause yielding:
