- - - - Constant system: Velocity remains constant
      - Reducing system: Velocity is reduced
      - Multiplying system: Velocity is increased

- - - - This uses a pinion that is a small cogwheel, mounted on a rack that is a
        toothed belt or bar
        
        the ratio between the number of rotations of the pinion and the velocity of
        the movement of the rack is expressed by: L=P·Z·N
    - - This consists of a bolt or threaded bar and a nut that has the same
        interior diameter as the diameter of the bolt
    - - A crank is a bar attached to an axle that is used to turn it. A winch and crank handle system consists of a drum that rotates and a crank handle that allows to pull or lift obiects
        
        A winch is balanced when it satisfies F·d=R·(R·r/d)
  - - - This is a rotating objet that pushes a follower as it moves.
      - A set of cams fixed on the same axle is called a camshaft.
    - - This consists of a wheel with an offcentre rotation axle that doesn't coincide
        with the centre of its circumference. the distance between them is called eccentricity
    - - This is a set of connecting rods attached to a jointed axle. Each of the
        joints of the axle acts as acrank
    - - This is composed of a crank and a rod called a connecting rod or link
