## anonymous 4 years ago 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?

the longer the lever, the less force you need to exert. therefore you should place your hand as far up along the hammers handle as possible and place the nail right inside the claw of the hammer. |dw:1328409633582:dw|

torque $\tau= F * r$ hence the larger the distance 'r', lesser force is required to produce the necessary torque. |dw:1328423363472:dw|
