- - - - Balanced lever: F x d = R x r
        
        Type 2: The resistance is between the fulcrum and the effort
        
        Type 3: The effort is between the fulcrum and the resistance
        
        Type 1: The fulcrum is between the effort and the resistance
    - - Movable pulley, to pulleys, one fixed and the other can move: F = R / 2
      - Compound pulleys or block and tackle
      - Fixed pulley, is immobile: F = R
  - - - D1 / D2 = N2 / N1
        
        N= Velocities D= Gear radio
    - - Z1 / Z2 = N1 / N2
        
        Z= Number of teeth
    - - N(wheel) = N(screw) x Z(grooves) / Z(wheel)
    - - Z1 / Z2 = N2 / N1
    - - (Z1 x Z3) / (Z2 x Z4)
    - - (D1 x D3) / (D2 x D4)
  - - - Nut and bolt system: The bolt, a threaded bar
      - Winch and crank handle: Its a drum that spins and lifts objects
        
        F=Rx((Rxr)/d)
        
        R= Resistance
        
        r= radius of the winch
        
        F= Force
        
        d= length of the crank handle
      - Rack and pinion system: A cogwheel mounted on a rack, a toothed bar
        
        L=PxZxN
        
        L= Velocity of rack's movement
        
        Z= Number of teeth on the pinion
        
        P= The distance between teeths
        
        Rotations per minute of teh pinion
    - - Crankshaft: A wheel spins and transmits the movement to many bars
      - Cam
      - Crank-link-slider: A wheel spins and an articulated bar goes into a slider
      - Eccentric cam
    - - For controlling the movement
        
        Disk brakes
        
        Ratchet
        
        Band brakes
        
        Drum brakes
      - That store energy
        
        By traction
        
        By torsion
        
        By compression
      - Connecting mechanisms
        
        Fixed connections
        
        Movable connections
        
        Clutches
      - Supports
        
        Bushings
        
        Bearings
