Explanation:

  • A lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum, used to transfer a force to a load and usually to provide a mechanical advantage.
  • On the basis of the locations of fulcrum, load, and effort, the lever is divided into three types.

First Class Lever

  • First-class levers have the fulcrum between the force and the load. 
  • ​Effort and the load move in opposite directions.
  • The effort in a class 1 lever is in one direction. 
  • Examples: See-saw, crowbar, scissors, claw and hammers, the handle of water pump, a beam balance, wire cutter, plier, etc.

Second-class lever

  • In second-class levers, the load is between the effort (force) and the fulcrum.
  • Effort and the load moves in the same direction.
  • Examples: Wheelbarrow, Staplers, Bottle openers, Nutcrackers, and Nail clippers.

Third-class lever

  • In third-class levers, the effort is between the load and the fulcrum.
  • Effort and the load moves in the same direction.​
  • Examples: Fishing rod, Broom, Baseball bat, Bow and Arrow Human jaw.
