Levers
A lever is a rigid bar that is supported by a fulcrum.
F·d=R·r
R is the resistance or load which acts at the other end of the bar.
d is the distance from F to the fulcrum
F is the force or effort appbed at one end of the bar.
r is the distance from R to the fulcrum
Compound pulley

Supports: bushings and bearings
In bushings the axle or the shaft is inserted in a plain circular piece
that is placed inside a housing to provide a bearing surface.
Bearings are made up of two concentric rings with balls or rollers between them.
