A single crystal of silver (FCC structure) is oriented such that a tensile load of 1,000,000 N is applied along the [001] direction. The single crystal is cylindrical and has a radius of 18 cm. The slip system for the FCC crystal structure is 111〈110〉. Using the FCC unit cell below, sketch a (111) plane and, using arrows, indicate two different 〈110〉 directions within this plan. Compute the resolved shear stress (in MPa) in the [101] direction on the (111) plane. If the critical resolved shear stress is 2.0 MPa, will the crystal yield? (explain how the answer is obtained
