Slip in NaCl-structure ionic crystals (such as NaCl, TiC, TaC, etc.) occurs most commonly on (110} planes and in /tio) directions. Draw the 110) plane and the 110 direction in a cubic cell of this crystal and determine the resolved shear stress upon application of a load of 1,000 N. The direction of load application is along the [211] direction of the crystal. The cross-sectional area of the crystal is circular and of 10-cm diameter.
