16、many of these terms have been placed in this standard.3.2 Terms that are defined in some textbooks may differslightly from those in this standard.

No significance should be placed on the order inwhich the symbols are presented where two or more are givenfor an individual term. The applicable units are indicated bycapital letters,

Degrees of angle are indicated as “degrees.”3.3.2 Expressing the units either in SI or the inch-poundsystem has been purposely omitted in order to leave the choiceof the system and specific unit to the engineer and theparticular application, for example:FL2may be expressed in pounds-force per s
