Question

Knife is an example of a lever of first order.

• A. True
• B. False

Answer 1

The correct option is B False

1. Third-order lever: When the effort lies in between the load and fulcrum, then the lever is said to be the lever of third order.
2. The knife is an example of the third order of lever because in this case effort (force exerted by hand in cutting) is in between the fulcrum and load.
3. While in the case of the first order of lever the fulcrum is between the load and effort.

Hence, the given statement is false.
