MACHINES AND MECHANISMS

MACHINES

Used to describe a set of elements or parts that work together and use energy to perform a task and obtain a result.

EXAMAPLES: Muscle strenght, in the case of scissors the sheet of paper.

MECHANISMS

Devices that transmit and/orconvert motion

EXAMPLES: Eccentric wheel, friction wheels, belt and pulley transmission. These are some examples of mechanisms

TYPES:

Motion transmission mechanisms:

LINEAR MOTION: Move in a straight line (levers, pulley...)

ROTARY MOTION: Move in circles (belt and pulleys, gears...)

Motion conversion mechanisms:

The mechanism coverts the movement from the drivier element into a movement that the driven element can cause.

EXAMPLES: screw and nut, cams, eccentric...
