(a) Consider a cylinder of FCC single crystal under tensile stress. The crystal is oriented such that its [120] direction is parallel to the loading axis and the measurement is performed at room temperature. Determine the primary slip system for this configuration and give the magnitude of the resultant Schmid factor (cosφ∙cosλ).
(b) If slip occurs at an applied tensile stress of 10 MPa, what is the material’s critical resolved shear stress?
(c) Assume you now replace the sample with a piece of borosilicate glass of the exact same shape and size. At what applied tensile stress will slip occur?

A single crystal of Al has the FCC crystal structure and is oriented such that a tensile stress is applied parallel to the [010] direction. If the critical resolved shear stress for this material is 0.2 MPa, calculate the magnitude(s) of applied stress(es) necessary to cause slip to occur on the (111) plane in each of the [1̅10] [1̅01] [011̅] Also, which of these slip systems is “preferred” for slip?
