Rotary motion mechanisms
Gear mechanisms with a chain
Gear mechanisms and cogwheels
Pulley with belt
Pulley trains with belts
Linear motion mechanisms
A lever is a rigid bar that is supported by a fulcrum.
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
Mechanisms that store energy
Mechanisms for controlling and directing motion
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.
Mechanisms that transform media
From rotary into linear
Nut and bolt system
Winch and crank handle
Rack and pinion system
From rotary into reciprocating motion
Controlling and regulating motion
