TYPES OF LEVERS CLASS 1, CLASS 2 & CLASS 3

TYPE 1 LEVERS  In a Type 1 Lever, the pivot (fulcrum) is between the effort and the load. In an off- center type one lever (like a pliers), the load is larger than the effort, but is moved through a smaller distance.

SEESAW, SCISSORS, HAMMER, PLIERS

CLASS 2 LEVER  the load is between the pivot (fulcrum) and the effort. The direction of the force is not changed.

STAPLER, WHEELBARROW, PAPER CUTTER, DOOR

CLASS 3 LEVER  The fulcrum is at one end & the effort is applied between the fulcrum & the load.
