Note: Motion, in mechanics, may be simple or compound. Simple motions are: (a) straight translation, which, if of indefinite duration, must be reciprocating. (b) Simple rotation, which may be either continuous or reciprocating, and when reciprocating is called oscillating. (c) Helical, which, if of indefinite duration, must be reciprocating. Compound motion consists of combinations of any of the simple motions. Center of motion, Harmonic motion, etc. See under Center, Harmonic, etc. — Motion block (Steam Engine), a crosshead. — Perpetual motion (Mech.), an incessant motion conceived to be attainable by a machine supplying its own motive forces independently of any action from without.
