Levers





The lever is a simple machine whose function is to transmit a force. It consists of a rigid bar which can rotate freely around the fulcrum (fulcrum).
can be used to amplify the mechanical force applied to an object to increase the distance or speed, in response to the application of a force .



Pulleys:

A pulley, also called pulley, carrucha, trochlear, sheaves or cheek, is a simple machine used to transmit a force. This is a wheel, usually solid and grooved edge, which, with the assistance a rope or cable that passes through the channel ("throat"), is used as the transmission element to change the direction of motion in machines and mechanisms. In addition, joint-forming equipment or hoists used to reduce the magnitude of the force required to move a weight, ranging in speed.
As defined by the Goupillières Haton, "the pulley is the fulcrum of a moving rope is wound on her without a full turn acting on one end the other the strength and power.

Hoist:

hoist is called a machine used to lift or move a load with a mechanical advantage, because you need to apply a force much less than the weight to be moved. Take two or more pulleys incorporated to minimize the effort.
These mechanisms are widely used in workshops or industries that carry many heavyweights because it's moving faster, lifting and placement of these heavy parts in the various machine tools that are in workshops, warehouses and loading and unloading trucks that carry them.
tend to be subject to a rotating arm that is attached to a machine, or may be movable guided by rails placed on the roofs of industrial buildings.
hoists are different in size or power lifting, small are manipulated by hand and have incorporated a larger electric motor.
