Question

Scissors belong to what class of levers?

• A. Class I
• B. Class II
• C. Class III
• D. (b) and (c) above.

Answer 1

The correct option is A Class I

Depending on the relative positions of the effort, load and fulcrum, levers are classified into 3 types:

• Class I: The fulcrum is situated between the load and the effort.
• Class II: The load is situated between the fulcrum and the effort.
• Class III: The effort is situated between the fulcrum and the load.

In a pair of scissors, the fulcrum is present in between the load (the cutting blades) and the effort (the handles) which make them a class I lever.
