Precession is a change in the orientation of the rotational axis of a rotating body. The equivalent of linear momentum in rotational motion is angular momentum. That modification improved roll rate by reducing rotational inertia. Flywheels resist changes in rotational speed by their moment of inertia. This implies that the kinetic translational energy dominates over rotational and vibrational molecule energies. It is a measure of rotational inertia. Vertical, orbital, vectorial, directional, helical, conical, rotational, spin and indexing machining cycles are also used. This is especially true in rotary-screw compressors that operate at high rotational speeds. The constituent molecules of a vapor possess vibrational, rotational, and translational motion. This inner gimbal has two degrees of rotational freedom. One motor with a constant rotational speed drives the capstan. The DOS of dispersion relations with rotational symmetry can often be calculated analytically. Consequently, the 3 degrees of freedom are partitioned into molecular translational, rotational, and vibrational motion. It has twelve lines of reflective symmetry and rotational symmetry of order 12. It has eight lines of reflective symmetry and rotational symmetry of order 8.
