Combination categories for multiple injuries are provided for use when there is insufficient detail as to the nature of the individual conditions, or for primary tabulation purposes when it is more convenient to record a single code; otherwise, the component injuries should be coded separately.
Oscillating is the process of swinging or moving to and fro in a steady, uninterrupted manner, and oscillating motion is the movement created by the process. An oscillating motion typically refers to a single step of the process in one direction then again as it swings to and from the opposite direction.
A normal mode of an oscillating system is a pattern of motion in which all parts of the system move sinusoidally with the same frequency and with a fixed phase relation.The free motion described by the normal modes takes place at the fixed frequencies.n a one-dimensional system at a given mode the vibration will have nodes, or places where the displacement is always zero. These nodes correspond to points in the mode shape where the mode shape is zero.
