cross section

n
1. (Mathematics) maths a plane surface formed by cutting across a solid, esp perpendicular to its longest axis
2. (Mathematics) a section cut off in this way
3. the act of cutting anything in this way
4. a random selection or sample, esp one regarded as representative: a cross section of the public.
5. (Surveying) surveying a vertical section of a line of ground at right angles to a survey line
6. (General Physics) physics a measure of the probability that a collision process will result in a particular reaction. It is expressed by the effective area that one participant presents as a target for the other
