If the translation vector of a glide plane operation is itself an element of the translation group, then the corresponding glide plane symmetry reduces to a combination of reflection symmetry and translational symmetry.

When a vacancy arrives at the place where the dislocation is stuck it can cause the dislocation to climb out of its glide plane, after which the point defect is no longer in its way.

Combining two equal glide plane operations gives a pure translation with a translation vector that is twice that of the glide plane operation, so the even powers of the glide plane operation form a translation group.

Principally, the simplest way to accomplish the yaw bearing tasks with gliding elements is with two gliding planes for the axial loads ( top and bottom ) and a radial gliding surface for the radial loads.

Schmid's Law states that the critically resolved shear stress ( ? ) is equal to the stress applied to the material ( ? ) multiplied by the cosine of the angle with the glide plane ( " ? " ) and the cosine of the angle with the glide direction ( ? ).
