Question

A claw hammer is used to pull a nail from a piece of wood. Where should you place your hand on the handle and where should the nail be located in the claw to make the effort force as small as possible?

Answer 1

Nail should be located at the bottom of claw as possible And hand should be place at the tip of handle as possible without losing perfect grip.

Load x Load distance = Effort x Effort distance

Effort = Load x load distance / Effort distance.

Answer 2

You will exert less force the more the lever is longer. So, you need to place your hands as high as possible with the hammers handle.
