   • It generates the movement in the machine.
4. Motor transmission elements

   Nota:

   • They transmit the motor's movement and power to the parts of the machine that use of them.

Nota:

• Total energy or absorbed energy | Machine | Useful work--Lost en.

Nota:

• HP=Horse Power

1. P total=P useful+P lost
2. Potence(P)=Work(W)÷Time(t) Watt(W)=Joule(J)+Second(s)
3. n=(P useful ÷P total) ×100

1. F a × d a = F c × d c
