Asingle crystal of aluminum is oriented for a tensile test such that its slip plane normal makes an angle of 28.1° with the tensile axis.
three possible slip directions make angles of 62.4°, 72.0°, and 81.1° with the same tensile axis.

(a) which of these three slip directions is most favored?

(b) if plastic deformation begins at a tensile stress of 1.95 mpa, determine the critical resolved shear stress for aluminum.
