(a) A single 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 direction on each of the (110), (011), and planes.

(b) On the basis of these resolved shear stress values, which slip system(s) is (are) most favorably oriented?
