- - - - 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.
  - - - The load and the effort are on opposite sides of the fulcrum
    - - The load is between the effort and the fulcrum
    - - The effort is between the fulcrum and the load
- - - - A fixed pulley is a wheel that has a
      - groove for a rope, cham or belt to go round
      - lt. It rotates around an axle that ls fixed to a wheel, crankshaft, etc rotates an immobile surface. This reduces the load.
      - R when elfort, f, is applied
  - - - A moveabie pullev has two pulleys — one
      - is fixed while the other can move m a imear
      - direr.tron.
  - - - This is a set of fixed and moveable pulleys, often called a block and
      - tackle. If we use more pulleys it bei.omes more complex, but less effort
      - is needed to move the load
- - - - Mechanisms are devices that transmit and convert forces and mouons
      - from a driving force hnput) to an output element.) hey enable us to
      - carry out certain tasks with greater comfort and less effort.
