| lever | 1. <mechanics> A rigid piece which is capable of turning about one point, or axis (the fulcrum), and in which are two or more other points where forces are applied; used for transmitting and modifying force and motion. Specif, a bar of metal, wood, or other rigid substance, used to exert a pressure, or sustain a weight, at one point of its length, by receiving a force or power at a second, and turning at a third on a fixed point called a fulcrum. It is usually named as the first of the six mechanical powers, and is three kinds, according as either the fulcrum F, the weight W, or the power P. Respectively, is situated between the other two, as in the figures. 2. <machinery> A bar, as a capstan bar, applied to a rotatory piece to turn it. An arm on a rock shaft, to give motion to the shaft or to obtain motion from it. Compound lever, a machine consisting of two or more levers acting upon each other. Lever escapement. See Escapement. Lever jack. See Jack. Lever watch, a watch having a vibrating lever to connect the action of the escape wheel with that of the balance. Universal lever, a machine formed by a combination of a lever with the wheel and axle, in such a manner as to convert the reciprocating motion of the lever into a continued rectilinear motion of some body to which the power is applied. Origin: OE. Levour, OF. Leveor, prop, a lifter, fr. F. Lever to raise, L. Levare; akin to levis light in weight, E. Levity, and perh. To E. Light not heavy: cf. F. Levier. Cf. Alleviate, Elevate, Leaven, Legerdemain, Levy. Source: Websters Dictionary (01 Mar 1998) |

| leverage | The action of a lever; mechanical advantage gained by the lever. <mechanics> Leverage of a couple, the perpendicular distance between the lines of action of two forces which act in parallel and opposite directions. Leverage of a force, the perpendicular distance from the line in which a force acts upon a body to a point about which the body may be supposed to turn. Source: Websters Dictionary (01 Mar 1998) |

A see saw is a lever familiar to everyone. A lever is a stiff rod or plank that rotates around a fixed point, or fulcrum. Downward motion at one end results in upward motion at the other end. Depending on where the fulcrum is located, a lever can multiply either the force applied, or the distance over which the force is applied. There are three kinds of levers, and which kind you have depends on where the fulcrum is set. ...
