Mechanisms
2.- Linear motion mechanisms
2.1.- Levers
A lever is a rigid bar that is suported by the fulcrum.
The law of the lever: F · d = R · r
Types
Class 1
Class 2
Class 3
2.2.- Fixed pulley
Is a wheel that has groove around it into which rope, chain or belt fits
F = R
2.3.- Moveable pulley
Is a set of 2 pulleys - one is fixed while the other can move in a linear direction
F = R / 2
2.4.- Compund pulley
Is a system of fixed and moveable pulleys, often called block and tackle
1.-Mechanisms
Are devices that transmit and convert forces and motion from a driving force or input element to an output element
3.- Rotary motion mechanisms
3.1.- Friction drives
3.3.- Gear mechanisms and cogwheels
3.2.- Pulleys with belt
3.5.- Gear mechanisms with a chain
3.6.- Gear train
