storing energy
transmiting motion
notary
linear
Driving forces
electric motor
muscles
spring
Mechanisms that transmit motion and force in a straight line from one point to another
pulleys
movable
is balanced when it satisfies this equation: F=R/2
compound
fixed and movable pulleys. (block and tacke)
fixed
is balanced when the effort F is equal to resistance of the load, R.
levers
rigid bar that is supported by a fulcrum
class 2
fulcrum on the right
class 3
effort in the middle
class 1
fulcrum in the middle
they produces movement: MOTION
