- - - - Driving force
        
        The driving force can be a spring, an electric motor or our own
        muscles.
        
        The driving force is the original force that would start the movement of the original moment, this initial force will eventually vanish, as there´s no perpetual force that has, or will ever exist.
      - Mechanisms
        
        Transmiting motion
        
        Linear
        
        Rotatory
        
        Transforming motion
        
        Controlling and regulating motion

        Storing energy
      - Output element
- - - - A lever is a rigid bar that is supported by a fulcrum.
        
        F is the force applied to at one end of the bar
        
        R is the resistance which acts at the other end of the bar
        
        d is the distance from f to the fulcrum
        
        r is the distance from R to the fulcrum
      - Types of levers
        
        Class 1
        
        The fulcrum is between the effort applied and the resistance
        
        The effect of the effort applied can be multiplied or reduced
        
        Class 2
        
        The resistance is between the fulcrum and the effort applied
        
        The effect of the effort applied is always is always multiplied.
        
        Class 3
        
        The effort applied is between the fulcrum and the resistance
        
        The effect of the effort applied is always reduced.
    - - Fixed pulley
        
        A fixed pulley is a wheel that has a groove around it into which a rope,
        chain or belt fits. It rotates around an axle that is fixed to an immobile surface.
      - Movable pulley
        
        A moveable pulley is a set of two pulleys. One is fixed while the other
        can move in a linear direction.
      - Compound pulley
        
        This is a system of fixed and moveable pulleys, often called block and
        tackle. If we use more pulleys, the system becomes more complex, but less force is needed to move the load.
