Homework Statement



How could mother nature have improved on our arm design so that we could lift larger loads?

Homework Equations



None.

The Attempt at a Solution



I really don't understand how our arm design could be improved. Perhaps our pivot point was moved must torque be maximized? I'm not sure at all!

I know that as the angle of the bicep decreases from the forearm (as you move your bicep and forearm closer), the force of bicep increases. If the angle of the bicep from the forearm increases (your arm is almost straight) the force of the bicep decreases.

Longer arms perhaps? I do know that chimps have longer arms and they are considerably stronger than humans for the most part.
