# Name the Three Classes of Levers and Distinguish Between Them. Give Two Examples of Each Class. - ICSE Class 10 - Physics

#### Question

Name the three classes of levers and distinguish between them. Give two examples of each class.

#### Solution

The three classes of levers are:
(i) Class I levers: In these types of levers, the fulcrum F is in between the effort E and the load L. Example: a seesaw, a pair of scissors, crowbar.
(ii) Class II levers: In these types of levers, the load L is in between the effort E and the fulcrum F. The effort arm is thus always longer than the load arm. Example: a nut cracker, a bottle opener.
(iii) Class III levers: In these types of levers, the effort E is in between the fulcrum F and the load L and the effort arm is always smaller than the load arm. Example: sugar tongs, forearm used for lifting a load.
