उत्तर
The class of a lever is determined by identifying which component, Fulcrum (F), Load (L), or Effort (E), lies in the middle position between the other two.
The levers are of three kinds:
Class I levers that have fulcrum in between the load and the effort.
Eg. See - Saw
Class II levers which have load in between the fulcrum and the effort
Eg. - Nut - Cracker
Class Ill levers which have effort in between the fulcrum and the Load
Eg. - Forceps.
