to generate one or a few mix sections3 by cutting an object into slim slices
- a set plane cutting right through a three dimensional item usually at right angles to your longest axis of this object
- a section created by a plane cutting a great perpendicular to its longest axis
- an example meant to be representative of an entire population
- (physics) the likelihood that a certain communication (as capture or ionization) takes spot between particles; assessed in barns
The conditions under which it is impracticable are (I) when the piece has either an extremely large or an extremely small cross section, and (2) when its cross section varies materially in different parts of its length.
