- - - - The lever is balanced when the effort F, multiplied by its distance d is
        
        equal to the load R multiphed by its distance from the fulcrum r.
        
        This is called the law of the lever, which is expressed by this equation.
        
        F x d = R x r
      - Types of levers
        
        There are three types of levers — class l, class 2 and class 3.
        
        They' re classified accordmg to the position of the load and effort
        
        apphed in relation to the fulcrum.
        
        Here are diagrams and examples of the three types of levers
  - - - Pulleys are used to raise and lower loads easily because we use our
        
        own weight to counteract them
        
        Uses: wells, gym equipment
- - - - The sistern of gears with a chain for bicycles, the cogwheels of a
      - clock, the lever of a seesaw, the pulley used to get water from a well are
      - some of the simplest mechanisms that are part of many mechanical
      - obiects.
