Now, I need some thoughts on punch/impact physics. How many ways are there to produce 4000N of force with a single punch? How fast would a normal fist be going? How big/small would a fist have to be to cause damage at that force? How much damage would be caused?

Which is more aerodynamic, sharp edges or curves?

It would probably have long, thin limbs, built like wings maybe. Let's say that the target speed is 100 m/s, and the "machine" is 6 meters tall, with the sole purpose of speed. What would you say it looks like?

I guess I've been asking the wrong questions... Alright, new question, how fast can an upright bipedal mechanism be made to run, what would it look like, and how big would it be?

Thank you. An unrelated question entirely, why can't I get these kind of results from Google?

I said previously my questions reach into sci-fi territory. I'm not asking if it exists yet, I'm asking if the structure is capable of running 40m/s.

By my previous investigations, the physical limit was 15m/s, while the world record was 9.8 or so m/s, but I think that can be pushed to 23-25 m/s at maximum without sustaining damage. I want to know if, in a hypothetical scenario, a machine free of endurance issues and physical wear with the...

Let me pose a new question, taking away the physical endurance issues, bodily wear and mental inhibitions, how fast could the mechanics of the ideal human body be pushed to go?

Yeah, I guess you're right. Still, that's only the first question I have, and I have no answers yet. I just want to know how fast.

I'm sorry, I have other questions, too. I just felt I would make one thread for all of my questions. Well, my next question goes into the realm of scifi. How fast could an upright bipedal running machine go?What would it have to look like to go that fast?

Well, I personally know almost nothing about professional running, but I would say that posture and pace have a lot to do with it, also the "spring in the step", breathing, the surface that is being tread, the friction between surfaces, air resistance, impact on each foot fall and how it affects...

Actually, I mean just talking from the human body alone without any external assistance, just physiology. This is so I have a base to work from, to make this part of the project feasible at least from a physics standpoint.

Thank you. Now, the first question has to do with running. More specifically, how fast can a human run, or rather, how fast can the ideal human run? I know the world record for running speed is just under 10m/s, but can greater speeds be achieved?

I am doing a passion project that requires knowledge of physics I don't quite have, it mostly revolves around understanding human bodies and their interaction with velocity, impact, decibels, energy, etc. I'll be more specific later on.
