- - - - N 1 · D1 = N1· D1 = D1 : D2 · N2:D1
      - • N1 and N2 are the velocities of the primary dmve wheel and the
        output wheeL
      - • D1 and D2, are the corresponding diameters
  - - - Their axles are paof the beltrallel and they rotate simultaneously due to the effect of the belt
  - - - The gear rauo between the dnve pulley (I) and the dnven pulley l4) depends
      - on the relauve size of the pulleys in the system. It's expressed as a function of
      - their diameters.
- - - - • F is the force or effort appbed at one end of the bar.
      - • R i s the resistance or load which acts at the other end of the bar.
      - • d i s the distance from F to the fulcrum
      - • r is the distance from R to the fulcrum
    - - The following equauon mdicates a balanced lever
      - F · d= f · r
      - It's called the law of the lever
    - - class 1
      - class 2
      - class 3
    - - A fixed pulley is balanced when the effort F is equal to the resistance of the load, R:
        
        F = R
      - Uses: wells and gym equipment, for example
  - - - A moveable pulley is balanced when it satisfies this equation
      - F = R : 2
- - - - The chain gear system of a bicycle, the gears of a clock or watch, the lever in a seesaw and the pulley in a is all are some of the simplermechanisms that can be fuund in many objects
    - - • transporting people from A to 8
      - • telhng the time
      - • en tertaining children in the park
      - • lif tmg and carrying objects
