If I'm screwing a wood screw into a piece of wood and my friend Charley is

the same. Screws are identical, but Charley is a lot stronger than I am.
We
turn the screws at the same RPM. Will Charley screw his screw in before
me?

If he's bigger and stronger, I'd bet on Charley. Even with the same
revolutions per minute, the depth of the stroke would be longer
because of Charley's available strength.

But, the total number of turns to screw it in will be the same.
