- - - - compression traction or torsion
- - - - Compound pulleys
        
        the force needed can be:
        
        load divided per the double of the number of pulleys
        
        F=R:2n
        
        load divided per 2 elevated to the number of pulleys
        
        F=R:2^n
      - Fixed pulleys
        
        The force is equal to the resistance load
        
        F=R
      - Movable pulleys
        
        The force needed is equal to the half of the resistance load
        
        F=R:2
      - Pulleys always need a supporting point to work
    - - class 2
        
        effort applied is multiplied
      - class 3
        
        effort applied id reduced
      - class 1
        
        efffort apply can by reduced or multiplied
      - Rigid bars supported by a fulcrum
  - - - gears and cogwheels
        
        Cogwheels are sets of wheels that have teeth called cogs
        
        They fit into the spaces between the others of other wheel so that
        moves the wheel
        
        Gears can be cylindncal or conical
        
        Z1:Z2=N2:N1
        
        there is also the worm gear
        
        the worm gear has a screw thatmoves a helical cogwheel that is set perpendicular
        to the screw
        
        Nw = Ns x Zg : Zw
        
        Gear mechanisms with a chain
        
        These are two cogwheels with parallel axles that are a certain distance apart, they rotate simultaneously by means of a metal chain or a toothed belt stretched over both wheels

        Gear train
        
        This is a system of more than two gears, connected together

        Pulley trains with belts
        
        1 more item...
      - They are two pulleys or wheels that are a certain distance
        
        they rotate simultaneously due to the effect
        of the belt.
        
        D1:D2=N1:N2
- - - - This is a set of connecting rods attached to a jointed axle. Each of the joints of the axle acts as a crank
      - Cam
        
        This is basically a rotating object
        that pushes a follower as it moves
