A rod-shaped single crystal of pure iron is to be tested in tension. The tensile axis is: [uvw]=[120]. Consider the {110}/111 slip system of this bodycentered-cubic iron specimen (with a purity of 99.96% ). Its critical resolved shear stress is reported to be: CRSS=27.5MPa. For each possible slip system, calculate the applied tensile stress needed to initiate slip. To help you organize your response and to make your answers easier to grade, I have provided a chart on the next page that you must use to report your answers. In many BCC metals, there are more slip systems that those mentioned, but we will ignore them for this problem. Calculations Necessary for This
