Is it pointless to create body armor that can withstand .50 BMG,

>>31366811
We just call it a tank

>>31366811
>the sheer force would cause you to die of internal injuries
That's just not true.

If it was, the shooter would have been killed by recoil.

>>31366811
>Is it pointless to create body armor that can withstand .50 BMG, because the sheer force would cause you to die of internal injuries.
no that's bullshit.
16kj is a lot of energy tho i think a knee in your guts would only deliver 2kj so it's like being kicked by a horse rather than a human. but survivable nevertheless if it is distributed properly.

>>31366873
Your logic isn't correct.

The force acted on the bullet in the gun for a .50bmg is over 28" of barrel length whereas the force of the bullet on the armor would be over ~2" of the bullet impacting. Not to mention other components like acceleration and momentum.

>>31366908
recoil is 4 times greater energy than the bullet carries tho there is that.

>>31366811
would the barrel be able to take that much force/energy/heat?

>>31366901
not it's wrong a human can punch up to 1kj and kicks are almost twice as strong knee even more devastating probably would be well above 3kj.

still 16kj man... that must suck ass.

>>31366935
Greater energy distributed over an even greater area

>>31366811
is this real

>>31367048
yes and longer time
>>31367073
no that faggy plastic shit would fold over from the first shot it almost does from pistol rounds

>>31366811
That image is cancer. The barrel is shorter than the round itself meaning it can't even be chambered.

>>31367215
Maybe it fires straight off of the magazine.

I've been waiting half my life for this website to finally fucking die. Since I first started browsing the internet I've been patiently waiting for the one day this abominable hive of furries and faggots would die off.

Will I ever have release from my torment?

Yes, it is pointless.
Yes, there may be a solution.
No, it would not be worth it.
Find yourself some hard cover and figure out what you did to make some faggot with an anti-materiel rifle start shooting at you.

>>31366873
HOLY SHIT HOW CAN YOU BE THIS FUCKING STUPID!?!?

>>31367287
So the bolt strips it from the magazine, then moves it backwards, then encloses around it like a chamber, then fires?
You clearly don't even understand how a magazine works or what happens to a cartridge which is fired outside the chamber.

>>31367215
On that note, I'm pretty sure there isn't enough room for the bolt to go all the way back too.

does anyone have the pic of the russian 6a (?) body armor?

>>31366811

>because the sheer force would cause you to die of internal injuries
Wrong.
As long as the force is distributed over a wide area (such as the area of a body armor plate) you'd be just fine as long as the plate doesn't deform significantly.

>>31367345
Let's not forget that the bolt of the Kriss goes down behind the magazine well. Clearly there is not remotely enough room for this to occur.

>>31366873
Look up what people look like after getting hit by pistol rounds while wearing plates. 9mm and .45 will crack ribs and can even stop your heart.
I've personally been shot by simunition while wearing body armor and it bruised me. That was a fucking BB.

>>31368984

You don't seem to understand the difference between a plate and soft armor.

>mfw no one in /k/ knows the difference between kinetic energy and momentum

>>31369126
kinetic energy: the energy that hits things
momentum: when you get going and try to stop

A strong enough plate with proper padding could stop it, if you decided you wanted to make one. If people can shoulder and fire it in a rifle then there's no reason why the same or less force over a much wider area would kill you.

But it would be a big vest.

Why

>>31369133

Kinetic energy doesn't "hit things"
Kinetic energy is the measurement of the work done to accelerate a given projectile to a given speed.
Saying kinetic energy hits things is like saying rotational inertia hits things, and makes you sound retarded.

What do you even think happens when a bullet hits something?
Do you think its kinetic energy shoots out an electrocutes the target or something?

Something with a lot of KE just means it took a lot of work to put the projectile into its current state.
It doesn't mean its a super deadly missile system that's going to "dump energy" into you and shock you to death or something.

You're fucking retarded.

>Is there a solution
Yes, you could technically make ridiculously thick padding.
>Would it be worth it?
No. Proper cover makes far more sense.

Also not related but your pic is fucking retarded for a multitude of reasons, mainly not enough space for bolt movement, not enough space for the chamber, etc.

Somewhat related - in theory, what FPS would be required on a common rifle round (let's say .30-06) so that it had the energy required to pierce the armor of a modern main battle tank?

>>31369345
You know the bottom bit is the barrel, not the top?

>>31366811
>Is there even a solution to it?

Yeah, it's called "don't get hit by a .50BMG bullet"

even if you miss a fifty cal will take your arm CLEAN OFF

my dad works at bartlett and shoots 500 fitty calipers a day from a ma deuce and theres basically arms fucking piled up from all the missed shots

its such a deadly round its banned from the geneva convention and only terrorists and gun nut army veterans use it and no armor can even defeat it nice try kid

Purely kinetically? A shitton.

Really the only way to pierce armor on modern tanks nowadays is by using shaped charges on the end of rockets.

For fun, however, I'll take the specs of a kinetic energy penetrator, such as the General Dynamics KEW-A1's specs of a 4kg penetrator at 1740 m/s.

(0.5)(4)(1740^2) = 6 million (oy vey) Joules.

The heaviest 30-06 on Wikipedia weighs 14g, or 0.014kg, so to reach 6 million Joules, we'll need (0.5)(0.014)(x^2) = 6 million, which solving for x gives us 29,411.37 m/s, or nearly 100,000 feet per second.

For reference, this is Mach 86.

For reference, this is 10,000 feet per second faster than the International Space Station orbiting the earth.

Ignoring air resistance because I'm a lazy fuck, you can actually shoot down the goddamn ISS with this thing.

Nigga what.

>>31366873
Hes not saying some dumb shit like the 50 will rip your arm off after passing by which is a myth. If you had a sapi plate rated for 50 bmg, the force of the round enacted on that plate would easily kill you. I dont know exact measurements but pretty sure you would shatter your ribs. Not to mention internal bleading. Could be wrong but a 50 is a monster of a bullet.

>>31371221
A steel plate ratd for .50 will probably weigh as much or more than the rifle that fired it.
With the force spread over a larger area you will feel the same kick as the guy firing it but with much less bruising.

>>31369710
You know nothing. You can shoot a 50 through a house of cards and they will not topple.

I think it would be possible but definitely isn't worth it.

>>31371187
Retard detected. lrn2physics

>>31371248
Youre right. If it was rated for 50 but only the same mass as one rated for 308, it would hurt a lot more. And a kick from a horse can kill a person, or another horse if landed properly

These questions gets asked so often that someone should create a sci thread and just screencap the best responses for future use.

Let's do some more fucking math. It's 12.20AM and I should sleep.

Going by Wikipedia, the largest .50BMG they have is 52g at 882m/s. Let's say that when you get shot by this thing it takes .25 seconds to reach a complete stop.

The total acceleration of this fucker is then 3528 m/s^2. Thanks to F=ma, we'll get a force of 183.456N.

Spread over a plate (I'll use the AR500's dimensions of 10x12 inches, or .0774m^2, we have 2369.644 N/m^s.

In Freedom Units, this is 0.3437psi. You'll survive.

>>31371359
>Let's say that when you get shot by this thing it takes .25 seconds to reach a complete stop.
The majority of the energy will be dumped into the plate much more quickly, no?

>>31371395
Shit starts to get painful around an impact time of 50ms, which gives you 0.3437psi * (250/50) * 10in * 12in, which comes out to a relatively painful 200 pounds of force for the duration.

For reference a blink of an eye takes about 100ms.

>>31371430
Thanks for the explanation.

>>31369786
Pretty interesting. Although at that speed, the bullet would be a blob of molten metal rather than a solid object anymore.

>>31366873
let's do a test in you.

Another viable solution is called "tank".
