Lever vs. Pulley

Levernoun

A crowbar.

Levernoun

(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.

Levernoun

Specifically, 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 of 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.

Levernoun

A small such piece to trigger or control a mechanical device (like a button).

Levernoun

(mechanics) A bar, as a capstan bar, applied to a rotatory piece to turn it.

Levernoun

(mechanics) An arm on a rock shaft, to give motion to the shaft or to obtain motion from it.

Levernoun

(rare) A levee.

Leververb

(transitive) To move with a lever.

Leververb

To use, operate or move (something) like a lever (physically).

Leververb

To use (something) like a lever (in an abstract sense).

Levernoun

a flat metal tumbler in a lever lock

Leververb

to move or force, especially in an effort to get something open;

Levernoun

a rigid bar resting on a pivot, used to move a heavy or firmly fixed load with one end when pressure is applied to the other

Levernoun

a projecting arm or handle that is moved to operate a mechanism

Lever

A lever ( or US: ) is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum. A lever is a rigid body capable of rotating on a point on itself.

Pulleynoun

One of the simple machines; a wheel with a grooved rim in which a pulled rope or chain will lift an object (more useful when two or more pulleys are used together, as in a block and tackle arrangement, such that a small force moving through a greater distance can exert a larger force through a smaller distance).

Pulleyverb

(transitive) To raise or lift by means of a pulley.

Pulleynoun

A wheel with a broad rim, or grooved rim, for transmitting power from, or imparting power to, the different parts of machinery, or for changing the direction of motion, by means of a belt, cord, rope, or chain.

Pulleyverb

To raise or lift by means of a pulley.

Pulleynoun

a simple machine consisting of a wheel with a groove in which a rope can run to change the direction or point of application of a force applied to the rope

Pulleynoun

a wheel with a grooved rim around which a cord passes, which acts to change the direction of a force applied to the cord and is used to raise heavy weights.

Pulleynoun

a wheel or drum fixed on a shaft and turned by a belt, used for the application or transmission of power.

Pulleyverb

hoist with a pulley

Pulley

A pulley is a wheel on an axle or shaft that is designed to support movement and change of direction of a taut cable or belt, or transfer of power between the shaft and cable or belt. In the case of a pulley supported by a frame or shell that does not transfer power to a shaft, but is used to guide the cable or exert a force, the supporting shell is called a block, and the pulley may be called a sheave.
