(a) asingle crystal of a metal that has the bcc crystal structure is oriented such that a tensile stress is applied in the [100] direction. if the magnitude of this stress is 4.0 mpa, compute the resolved shear stress in the [111]direction on each of the (), and (101)planes.(7 pts)(b) on the basis of these resolved shear stress values, which slip system(s) is (are) most favorably oriented? (1 pt)
