System consisting of a bar pivoting on a fulcrum to lift a load. The amount of effort required is related to the position of the pivot and the length of the bar.
Rigid moving bar around the fulcrum on which an effort is exerted to lift the load.
Weight whose inertia exerts a force opposite to the effort exerted on the bar.
Force exerted on the lever bar in order to shift the load.
Part providing an efficient fulcrum for the lever.
Point around which the lever pivots.
