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 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.
A bar, as a capstan bar, applied to a rotatory piece to turn it.
a rigid beam that can rotate about a fixed point. The point of rotation is the fulcrum or pivot. The fulcrum is the part of the lever that does not move. The idea of a lever is based on three things: effort or force; distance; and balance. The greater the distance between the lever and the fulcrum, the greater the load that can be moved. The longer the lever, the greater its mechanical advantage.
A long, stick or rod pivoting on a stable point, used to lift (or move) something massive with relatively little force. A lever has two arms, each running from the pivot point to one end of the rod. A massive body at the end of the short arm can be lifted up by the weight of a less massive body on the end of the longer arm.
a rigid bar used to apply pressure at one point along it's length by applying a force (effort) at a second point and turning about a third point or fulcrum. There are 3 classes of levers, called 1st, 2nd, and 3rd order. Oars having the fulcrum located between the handle and the blade are levers of the 1st order. Oars having the handle located between the fulcrum and the blade are levers of the 3rd order.
1. Rigid bar that is used to move or pry something. 2. Device which has a bar turning around a fixed point, the fulcrum or support, using power or force applied at a second point to lift or sustain a weight at a third point.
a bar that is free to pivot, or move about, a fixed point when an effort force is applied
rigid bar that moves about a fixed point. Bones act as levers in body.
a limb that transmits and modifys force or motion when forces are applied at two points and turns about a third
a rigid bar pivoted about a fulcrum
a simple machine that gives a mechanical advantage when given a fulcrum
to move or force, especially in an effort to get something open; "The burglar jimmied the lock", "Raccoons managed to pry the lid off the garbage pail"
a bar or plank used to move things
a bar that turns about a pivot point and is used to transfer and/or multiply force
a device that applies force or transfers it
a device that consists of a rigid bar that moves on a fulcrum, using force applied at a second point to lift up resistance at a third point
a fixed body, typically a metal bar, pivoted on a fixed fulcrum used to move or lift a load
a long stick that can be used with or without a wedge-shaped fulcrum
an arm that "pivots" (or turns) against a "fulcrum" (or point)
an inflexible or rigid rod that is able to rotate about a fixed point called the fulcrum
a particular stiff rod this rotates around a particular pivot point
a rigid bar on which a given load is moved with supporting help from a fulcrum
a rigid bar that moves on a fixed point, or a fulcrum, when a force is applied to it
a rigid bar that pivots to exert a force
a rigid bar that rests on a fulcrum (a fixed point
a rigid bar that rotates about a fixed pivot called a fulcrum
a rigid bar that rotates around a fixed point called a fulcrum
a rigid body pivoted on a fixed fulcrum
a rigid body used with a fulcrum, or pivot point, to magnify the mechanical force that can be applied to another object
a rigid body, which is free to turn about a fixed point called the fulcrum
a rigid structure, hinged at one point and to which forces are applied at two other points
a rigid support that pivots on a point
a rod or arm that tilts around a fixed central point when some force is applied
a simplemachine that magnifies speed of movement or force
a stick or pole resting on a pivot somewhere along its length, though not in the middle
a stick which rests on a fulcrum near one end
a stiff bar or rod that rests on a support called a fulcrum (pronounced FULL-krum) and which lifts or moves something
a stiff periodic table of the elements silver rod that rotates around
a stiff rod that rotates around a pivot point
a straight rod or board that pivots on a stationary point called a pivot point or a fulcrum
A rigid body that can rotate about a fixed point.
A rigid bar (like a bone) pivoted on a fixed point - used to transmit force, as in raising a weight at one end by pushing down on the other.
A rigid bar that rotates around a fixed support (fulcrum) in response to an applied force; A lever transmits and modifies force or motion. The bones act as levers in the body.
A simple machine consisting of a rigid bar that is free to pivot on a fulcrum.
Any pivoting element and anchor-shaped part made of steel or brass that is part of the escapement.
Any rigid bar that turns about a fulcrum or point when effort is applied. In the process of turning, resistance is overcome. An adjustment may be defined as a force or effort applied to a lever to activate it.
bar used to lift heavy object or pry open something.
In physics, a lever (from Old French levier, the agent noun to lever "to raise", c. f. levant) is a rigid object that is used with an appropriate fulcrum or pivot point to multiply the mechanical force that can be applied to another object. This is also termed mechanical advantage, and is one example of the principle of moments. The principle of leverage can also be derived using Newton's laws of motion, and modern statics.
