need torque formula help

Hi all,

looking for the formula, not the answer so much.


if you have a hammer to pull a nail, the claw is, say, 1 inch from the nail.

if you use a crowbar, the claw is 3 inches.

The handle is 1 foot in both cases.

What I am trying to determine is the pulling action at the nail.

what has me stumped is that the simple formula, F=weight x distance does not offer the offset.

can I just use the hypotenuse to calculate force ?

Thanks!

Dave
