Question

Why does a spanner have a long handle?

TNSCERT Class 10 Physics Ch 15 Laws of Motivation and Gravitation

Answer 1

A spanner have a long handle it is because, if the arm length is long, then the moment of force will be high, then, less force is only needed to do the desired action for the spanner. Thus, to reduce the required force, which is to be exerted, the spanner have a long handle, which also increases the moment of force.
Moment of force=force*arm length.

Hope this answer will help you.

Answer 2

Because if the arm length is long then the moment of force will be high then less force is only needed to do the desired action for the spanner have a long handle which also increases the moment of force.
