Question 2 The following data were taken relating to the deformation of zinc single crystals. The crystals have a normal cross-sectional area of 122106m2. = angle between loading axis and normal to slip plane = angle between loading axis and slip direction F= force acting on crystal when yielding begins a) What is the preferred slip system for this material? b) Calculate the resolved shear stress RSS and normal stress n acting on the slip plane when yielding begins (for all data) c) Based on your results, determine whether RSS or n control yielding in this material. d) Create a plot of the normal stress F/A0 versus the Schmid factor. At what value of the Schmid factor is the stress minimum? Is there a possible explanation for this behavior
