Optimizing Arm Design for Maximum Strength: Insights from Nature's Creations

AI Thread Summary
Mother nature could enhance human arm design for greater load-lifting capacity by optimizing the pivot point to maximize torque. The angle between the bicep and forearm significantly affects the force exerted by the bicep, with a smaller angle increasing force. Additionally, longer arms, as seen in chimpanzees, contribute to greater strength, suggesting that arm length plays a crucial role in lifting ability. The discussion highlights the relationship between arm mechanics and strength, emphasizing the potential for evolutionary improvements. Overall, analyzing natural designs can provide insights into optimizing human arm function.

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.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
