Question

Name the class to which the following levers belong:

(a) A pair of scissors

Answer 1

1. Levers are the most basic machines that are used to do some work with minimal effort.
2. A lever amplifies an input force to provide a greater output force, which is said to provide leverage.
3. First-Class Lever is a type of lever that has the fulcrum in between the weight and the force applied.
4. Its order is represented as force-fulcrum-weight.
5. For pair of scissors, the fulcrum is placed between the weight and the force applied.
6. Thus, pair of scissors belong to first-class levers.
