LINEAR TRANSMISSION OF MOTION: LEVERS

A lever is a rigid bar that turns around a point called a fulcrum. Law of the lever :

Fxd = Rxr

Classes of levers:

-Class 1 levers: increase the force that we apply and the distance that the end of the levers move.



-Class 2 levers: increase the force that we apply.



-Class 3 levers: increase the distance that the end of the lever moves.
