a) Calculate the Schmid factor for all possible slip systems for slip of a single crystal of a FCC metal pulled in the [121]. Hint: by using the dot product and noticing when cosφ and cosλ are zero you can save yourself some work.b) On which slip system(s) will slip occur first?c) If the critical resolved shear stress is 10 MPa, what is the yield strength?
