Together with filtre, lever is one of the few repetitive fundamental structures in the universe. Lever also acts as a tool although the concept covers lever and leverage also in a figurative sense.

Both figuratively and in physical mechanics lever is used to obtain an advantage. This advantage can be a real physical advantage or an imaginary advantage.

In physical mechanics a lever (from the French word “lever” "to lift up") is a nonelastic object that by applying it to a pivot point or fulcrum multiplies the force that can be delivered to another object. This is what is called mechanical advantage.

By advantage is meant obtaining the maximum output of desired "results" in exchange for the minimum input or expenditure of energy.

Lever is one of the half dozen basic machines invented by the human being for making life easier.

There are many specific examples: crowbar, pulley, cogwheels, pliers, nutcrackers, wheelbarrow, wrench and many others... even the wheel is a sort of lever which enables the preventionof friction to be minimized.

The principle of leverage is closely related to Newton’s laws of mechanics. See forthcoming Newton 2 magazine article

In a figurative sense lever and leverage is present whenever and wherever influence is exerted for the purpose of obtaining or increasing a particular advantage. This influence may involve any number of external tangible incentives or internal intangible incentives.
