[210] direction, which of these slip systems will be activated first? Along which directions will slip steps be observed on {111} type surfaces? A cylindrical fcc single crystal of Al is loaded in tension on a tensile testing machine. The cross sectional area of the cylinder is 1 cm2 and the [112] axis is parallel to the applied tensile load. The critical resolved shear stress of Ag is 6 x106 dynes/cm2 . What tensile force must be applied to plastically deform this crystal by slip?
