Part 350

Fric"a*tive (?), a. [See Frication.] (Phon.) Produced by the friction or rustling of the breath, intonated or unintonated, through a narrow opening between two of the mouth organs; uttered through a close approach, but not with a complete closure, of the organs of articulation, and hence capable of being continued or prolonged; -- said of certain consonantal sounds, as f, v, s, z, etc. -- n. A fricative consonant letter or sound. See Guide to Pronunciation, ßß 197-206, etc.

Fric"a*trice (?), n. [Cf. L. frictrix, fr. fricare to rub.] A lewd woman; a harlot. [Obs.] B. Jonson.

Fric"kle (?), n. A bushel basket. [Obs.]

Fric"tion (?), n. [L. frictio, fr. fricare, frictum,to rub: cf. F. friction. See Fray to rub, arid cf. Dentifrice.] 1. The act of rubbing the surface of one body against that of another; attrition; in hygiene, the act of rubbing the body with the hand, with flannel, or with a brush etc., to excite the skin to healthy action.

2. (Mech.) The resistance which a body meets with from the surface on which it moves. It may be resistance to sliding motion, or to rolling motion.

3. A clashing between two persons or parties in opinions or work; a disagreement tending to prevent or retard progress.

Angle of friction (Mech.), the angle which a plane onwhich a body is lying makes with a horizontal plane,when the hody is just ready to slide dewn the plane. This angle varies for different bodies, and for planes of different materials. -- Anti-friction wheels (Mach.), wheels turning freely on small pivots, and sustaining, at the angle formed by their circumferences, the pivot or journal of a revolving shaft, to relieve it of friction; -- called also friction wheels. -- Friction balls, or Friction rollers, balls or rollers placed so as to receive the pressure or weight of bodies in motion, and relieve friction, as in the hub of a bicycle wheel. -- Friction brake (Mach.), a form of dynamometer for measuring the power a motor exerts. A clamp around the revolving shaft or fly wheel of the motor resists the motion by its friction, the work thus absorbed being ascertained by observing the force required to keep the clamp from revolving with the shaft; a Prony brake. -- Friction chocks, brakes attached to the common standing garrison carriages of guns, so as to raise the trucks or wheels off the platform when the gun begins to recoil, and prevent its running back. Earrow. -- Friction clutch, Friction coupling, an engaging and disengaging gear for revolving shafts, pulleys, etc., acting by friction; esp.: (a) A device in which a piece on one shaft or pulley is so forcibly pressed against a piece on another shaft that the two will revolve together; as, in the illustration, the cone a on one shaft, when thrust forcibly into the corresponding hollow cone b on the other shaft, compels the shafts to rotate together, by the hold the friction of the conical surfaces gives. (b) A toothed clutch, one member of which, instead of being made fast on its shaft, is held by friction and can turn, by slipping, under excessive strain or in starting. -- Friction drop hammer, one in which the hammer is raised for striking by the friction of revolving rollers which nip the hammer rod. -- Friction gear. See Frictional gearing, under Frictional. -- Friction machine, an electrical machine, generating electricity by friction. -- Friction meter, an instrument for measuring friction, as in testing lubricants. -- Friction powder, Friction composition, a composition of chlorate of potassium, antimony, sulphide, etc, which readily ignites by friction. -- Friction primer, Friction tube, a tube used for firing cannon by means of the friction of a roughened wire in the friction powder or composition with which the tube is filled. -- Friction wheel (Mach.), one of the wheels in frictional gearing. See under Frictional.

Fric"tion*al (?), a. Relating to friction; moved by friction; produced by friction; as, frictional electricity.

Frictional gearing, wheels which transmit motion by surface friction instead of teeth. The faces are sometimes made more or less V-shaped to increase or decrease friction, as required.

Fric"tion*less, a. Having no friction.

Fri"day (?), n. [AS. frigedÊg, fr. Frigu, the gooddes of marriage; friqu love + dÊg day; cf. Icel. Frigg name of a goddess, the wife of Odin or Wodan, OHG. Fratag, Icel. Frjdagr. AS. frigu is prob. from the root of E. friend, free. See Free, and Day.] The sixth day of the week, following Thursday and preceding Saturday.

Fridge (?), v. t. [AS. frician to dance, from free bold. Cf. Freak, n.] To rub; to fray. [Obs.] Sterne.

{ Frid"stol` (frd"stl`), Frith`stool" (frth"stl`) }, n. [AS. fristl. See Fred, and Stool.] A seat in churches near the altar, to which offenders formerly fled for sanctuary. [Written variously fridstool, freedstool, etc.] [Obs.]

Fried (frd), imp. & p. p. of Fry.

Friend (frnd), n. [OR. frend, freond, AS. freÛnd, prop. p. pr. of freÛn, freÛgan, to love; akin to D. vriend friend, OS. friund friend, friohan to love, OHG. friunt friend, G. freund, Icel. frÊndi kinsman, Sw. fr‰nde. Goth. frijnds friend, frijn to love. √83. See Free, and cf. Fiend.] 1. One who entertains for another such sentiments of esteem, respect, and affection that he seeks his society and welfare; a wellwisher; an intimate associate; sometimes, an attendant.

Want gives to know the flatterer from the friend.

Dryden.

A friend that sticketh closer than a brother.

Prov. xviii. 24.

2. One not inimical or hostile; one not a foe or enemy; also, one of the same nation, party, kin, etc., whose friendly feelings may be assumed. The word is some times used as a term of friendly address.
