A lever is a simple machine that allows mechanical force to be exerted using a varying distance. Typically, the lever allows the use of a smaller force across a greater distance in the place of a larger force over a smaller distance.

What are the things that are belongs to lever?
a machine helps us do work because it can a)multiply force, b)multiply distance, or c)change the direction of force.
Does a third class lever increase the distance a load can be moved?
Levers can turn a small applied force into a large force. The same amount of work is done, though. So the small force must be applied over a larger distance, and the large force acts for a small distance. I think for the second way: you can configure a lever to operate in the same direction as the applied force, or in the opposite direction, depending on where the pivot point is. So it can change the direction of the force.
Can a force produce a torque when there is no lever arm?
no because to get a torque you must multiply lever arm by force. If lever is zero, then torque is zero
True or false The fulcrum is closer to the force when a force multiplier lever is used?
False. A lever to multiply the force exerted has its fulcrum closer to the object than to the force is applied. This will increase the force but decrease the distance the object moves compared to the force end.
How do you measure the effort distance in a lever?
Measure the distance from the fulcrum to the effort?
What a lever does?
A lever is a simple machine that uses variable distance to multiply force, or to redirect existing forces. With a lever, the force exerted by gravity on a weight can be used to lift another weight. By varying the distance between a lever's ends and its fulcrum, a heavy object can be lifted a short distance by a smaller force moving a longer distance.

Is a third class lever a force mulitplier or distance mulitplier?
Levers are used to multiply the mechanical force applied to a load.
What could multiply force greater a wedge or a lever?
lever
What is another word for fulcrum?
The fulcrum is the support about which a lever pivots.The fulcrum is the pivot point in a lever (or other simple machines ) to either multiply the mechanical force (effort) that can be applied to another object or resistance force (load), or multiply the distance and speed at which the opposite end of the rigid object travels. =]

False. A lever to multiply the force exerted has its fulcrum closer to the object than to the force is applied. This will increase the force but decrease the distance the object moves compared to the force end.
What are the function of a lever?
The lever helps you lift objects you can't physically lift. It uses Archimedes' leverage principle.Levers can also redirect force to make it easier to apply :-- a hammer uses the lever principle to pull out a nail-- seesaws balance a downward force (weight) on either side to lift the opposite sideA lever has two possible applications:-- multiply the force you apply and make it a larger force, by sacrificing the distancethat the force moves through;-- multiply the distance through which you move a force and make it a larger distance,by sacrificing the strength of the force.The product of (force) multiplied by (distance) is always the same at both ends of the lever.But by using the lever, you trade a part of one of them in order to increase the other one.A lever allows you to lift and elevate an object up in the air.>It gives you mechanical advantage (MA)MA = distance moved by effort / distance moved by loadOutput force = input force * MA
How do you measure the effort distance in a lever?
Measure the distance from the fulcrum to the effort?
How do you find the output force of a 1st class lever?
Multiply (the input force) x (the lever's mechanical advantage).
What is the relationship between distance from the fulcrum and the mechanical advantage of a first class lever?
The mechanical advantage of a First Class lever is Distance of the effort from the fulcrum/Distance of the load from the fulcrum
