Consider a single crystal cylindrical specimen of iron oriented such that a tensile load is applied along a [010] direction. The diameter of the specimen is 0.5 cm.
A single crystal of aluminum is oriented for a tensile test such that its slip plane normal makes an angle of 30o with the tensile axis. Three possible slip directions make angles of 58.4o, 72o, and 81.1o with the same tensile axis.
