Characteristics:
(1) It is a composition of links.
(2) There is a determined relative motion between links.
(3) It can transform or transmit energy.
☆ Machine: It is a system of links that can accomplish
determined motion and transform energy.

2)Link—Motion element (rigid construction)
e.g. Crank 4+4’+4”; Gear 5+5’+5”
Including: Driving (input) link
Driven (output) link
Frame
Different with:
Machine element—Manufacturing element
e.g. Coupler 3: body, nut, bolt,…

3) Mechanism
●Definition: A composition of links that can accomplish
determined motion. The difference between mechanism and machine
is: Whether it transforms or transmits energy.
◆ Mechanism: (internal part) Construction, kinematics, dynamics properties
◆ Machine: (external part) Transformation of energy
