How many Newton’s are needed to break an arm

[Mapl3Sy4up]

That’s it. Title says it all. Though I need this in terms of compressive strength (breaking it via grip)

I imagine it depends on how much of the arm is broken. If the entire arm is broken, as in every inch of the bone is completely shattered, you can take the surface area of the bone, and multiply it by the compressive strength of bone. If it only broke in the areas the person's hand was on, you can probably use the surface area of the hand for the parts that were broken, albeit that wouldn't be entirely accurate.

The latter is far easier to get, and the former is harder. Upon a basic google search, I can tell you I'm not getting many results for the surface area of an arm bone. If I were to get that though, calculating the lifting strength needed to crush it would be doable.

Oh I just need the forearm I might get the surface area by being more specific on the actual bone names? Edit: wait rereading your question yeah only the area his hand was on broke thank you

What’s the compressive strength of bone?

170 MPa according to wikipedia

So the average surface area of the male hand is 448 cm2, so how would the equation go here?

Need the surface area of the palm, as in, the frontal impact area. That's about 77.85 cm^2.

 

[Mapl3Sy4up]

Is it like multiplying the 170 Mpa by 77.85 and then putting that from Mpa to Newton’s or is it division?

 

[KLOL506]

You multiply the MPa value with the surface area to get your Newton value, yes.

 

[Mapl3Sy4up]

You multiply the MPa value with the surface area to get your Newton value, yes.

so 170 Mpa x 77.85cm^2 is 13720Mpa per cm^2 so do I just translate that to Newtons?
That’s 1372000 Newton’s or 137.2 tons of force? So this character gets class K? It’s the Sony Morbus I will make a God of 8-C out of this trash tier movie

Depends upon the angle of impact of attack. If the hand was reduced to bloody bits however, maybe. Simply bone-cracking requires a lot less force, prolly 300-500 psi I'd reckon.

Nah it wasn’t, it was a very casual “here Lemme just break the bones in your forearm for you” but iirc it was a very awkward grab

Then the force could be nerfed considerably

So like in class 100? with how casual it was I wouldn’t be surprised if the full strength Morb could fully preform the feat

Worse. To Peak Human to Class 1.

bruh noise

Wait so Your telling me a Class K feat if done casually instead of smashing it to bits (which was done because Morbius didn’t want to kill people at this point) gets millions of times weaker?

No what I am saying is, for the feat to be Class K, there needs to be evidence that the hand was reduced to a bloody mess with splinters of blood and bone flying all over, casual or not.

Ah ok. there wasn’t blood and bone going everywhere, it was just a grab and then crunch so I'm assuming the total has to be divided by something? Or is it just an entirely different way of calculating it?
also how do the throwing feats work? Like I've seen people use throwing things as a way to get a LS value. How's that work

F= ma.

You need to find the difference between final velocity and initial velocity then divide it by time taken to get acceleration. Then you multiply mass with said acceleration.

It's apart of the Morbius movie. We're gonna have to wait a month or two if I cant find a spanish clip

Ah, ok

can I use people for this?

Do you mean can you calculate people being thrown? If so, yes. Just as long as they're being thrown. If they're getting launched by a punch or kick, it doesn't count towards lifting strength.
