12Axial ratio — Axial ratio, for any structure or shape with two or more axes, is the ratio of the length (or magnitude) of those axes to each other the longer axis divided by the shorter.In chemistry or materials science , the axial ratio (symbol P) is used to… …
13Aspect ratio — The aspect ratio of a shape is the ratio of its longer dimension to its shorter dimension. It may be applied to two characteristic dimensions of a three dimensional shape, such as the ratio of the longest and shortest axis, or for symmetrical… …

16Extremal length — In the mathematical theory of conformal and quasiconformal mappings, the extremal length of a collection of curves Gamma is a conformal invariant of Gamma. More specifically, suppose thatD is an open set in the complex plane and Gamma is a… …
17F-ratio (disambiguation) — F ratio or f ratio may refer to:* f number, f ratio, or focal ratio, the ratio of the focal length of an optical system to the diameter of its entrance pupil; * f ratio, in oceanography, which relates recycled and total primary production in the… …
18fineness ratio — The ratio of the chord to the maximum thickness of an airfoil expressed as a percentage. In the case of other streamlined bodies, it is the ratio of their length to their maximum diameter, or, sometimes, to some equivalent dimension. This is said …
19bore-stroke ratio — The relation between the diameter of the cylinder bore and the length of the stroke of the piston. If the stroke is longer than the cylinder bore diameter then the engine is called a long stroke engine. If the stroke is shorter than the cylinder… …
