If I, as a person with long forearms, lift the same weight as a person with forearms half my length, am I twice as strong due to the increased moment at my elbow?

I was wondering whether strength scales linearly this way, because moment does scale linearly with the radius it is applied it.


EDIT: Guess I didn't clarify, I was thinking about bicep curls when I wrote this question.

While this is true, also consider that your upper arms would be twice as long as theirs, and so the *volume* of your muscle would be well over twice what theirs would be.  So actually, you'd be weaker per unit volume of muscle.

The linear force that your muscle could produce would be higher than theirs, though.
