#### 3.12.3.3 Centrifugal Body Force

A centrifugal body force per mass may be used for bodies undergoing steady-state rotation with angular speed about a rotation axis directed along and passing through the rotation center . Here, represents the distance of each material point from the axis of rotation, and is the radial unit vector from the axis of rotation, both of which are calculated internally from the knowledge of and .
