It would be nice to see the bullet proof vest working on a info-graphic or diagram. I didn't quite understand how the fabric increase the area of impact.
Kevlar (TM) is a DuPont trademark and there are other similar materials around. The generic is Poly-paraphenylene terephthalamide :-) Remember that the Fiber will stop or trap a small arms round but you still need a trauma pack behind that to absorb the energy. Will you may not die from the actual round entering your body the kinetic energy can also do damage can cause internal bleeding and tearing of organs.
quick explanation of how bulletproof vests work!: they prevent bleeding if you wear them and get shot, you will still feel the pain. some bullets are strong enough to penetrate the bulletproof vests like the ap rounds
"Leather armour of Roman soldiers"? Roman soldiers had chain and scale armour (known as lorica hamata and lorica squamata respectively) at the time of the Republic and, by the time of the Empire, Roman legionaries were using armour made of segmented iron plates called lorica segmentata. So the Romans had much more advanced armours than you think. They never used "leather armour". That is just a Hollywood fantasy. And Knights weren't the only people who had armour in the medieval period.
They have found bronze plate armour dating back to the fifteenth century BC. This notion that plate armour wasn't used before the Middle ages is simply false.
There has been interesting research into the use of non-Newtonian liquids to create body armour. When such a liquid is compressed or impacted it hardens, the greater the impact, the harder it gets. If you filled up a swimming pool with custard you would be able to run across it without sinking because of the impact of your feet on its surface.
The United States military has used ceramic plates contained in a kevlar vest for a while now (since at least 1996, according to some quick research). Most commonly aluminum oxide, boron carbide, and silicon carbide. Correct me if I'm wrong, but I don't think that non-newtonian fluids have ever been a component of body armor historically, but once again some quick research tells me that body armor incorporating such fluids is in development.
Ceramic armor works by using the bullets energy to shatter the ceramic instead of punching a hole through your body. Of course the ceramic is compromised after the first shot. So if a large enough piece survives you can still hope a second bullet lands there. Of course you can use hardened materials and armor plates to shatter the bullet and distribute the force. In any case, getting shot is going to leave some hurts.
Also overheating wasn't the main issue but fatigue from fighting. A cloth cloak with your coat of arms on it could stop the sun from heating up the armor (hence why the Knights Templar wore their famous cloaks over their chainmail).
+Vyppaaa11 * in a longer casing, meant for use in a gun that was reinforced in a way that would let it be able to use both rounds. ie a .44 magnum revolver can shoot both .44 magnum and .44 special, however a .44 special revolver can not fire the magnum round.
Well fair enough but there's lots more to it. There are fabric vests with multible layers of (if I recall correctly) fiber glass cloths and I'm sure some will have carbon fibers. There's also a kind of dragon skin vests with scales. These are the modern approaches, But military armor vests still have to have heavy plates protecting the vital body organs against high power rifles. Howerver 15kg is of course the max.
because thats the way it is, the way it will be and it is the way that wont change anytime soon, just because you cant handle ads doesnt mean people wants them to disappear and then youtube would be a pay per view site with monthly subscription
James May is the perfect one for these videos. Hamster would be off the walls and Clarkson would make some awkward joke about Germans being really good at shooting people.
This is quite tricky actually.James is right about the pressure,of the force/surface as the bullet's advantage to pierce concrete walls and bullets are stopped by carbon fiber and kevlar layers but in the same time going through some cheap solid body armor.Now if you apply the same thing to the knife,it means it would be stopped by the textile vest,when it actually isn't.So how you choose between a vest that can stop bullet but not knifes (textiles) or knifes but not bullets (solid) ones ? I guess its the type of fight you're going too. P.S. Do you know,guys,that millitary head cap its actualyl useless and can be punctured by the lightest handgun (despite the fact its round and you would think bullets will deflect of it) and that is there only for moral support ?
Because a high rpm engine puts lots of strain on the compenents, they get hot, have to cope with very high g force and also valve timing becomes a problem, thus the engine will fair quickly. However by just increasing the size of the engine by adding more cylinders no more strain is put on each piston and you still get the increase in power.
Arrows possibly but not swords since they don't protect well against cutting. There are some vests that incorporate a modern version of chain mail though which protect against stabbing and cutting.
Newton is for force. Weight is just mass of the object on earth, which by our measuring standards corresponds with the mass of the object. So as long as we don't leave the earth's gravitational field at sea level, weight and mass can be used interchangeably.
3:34 Bullets don't bounce off of ceramic plates. The plates are actually pretty fragile. They break up the bullet and then the Kevlar is able to absorb the bullet fragments.
The weight of an object can change depending on where you are in the universe, the mass doesn't. And Newton is used for weight, as weight is just gravitational force.
one is "weapon of future"(don't the english/us version of it),but it still doesn't quite cover eveything... i don't know,anyway the host of it (Richard Machowicz) has worked with some of this stuff,so check it out.
1. It increases the surface area in which the bullet has it's effect on. 2. It deforms the bullet, further increasing it's own area and reducing it's perforating capabilities. 3. It is paired up with hard plates to stop rifle rounds. All of this was described in the video. They're sorry they didn't have pretty 3D graphics explaining it. Actually, they're probably not.
Kevlar is the soft armour he was talking about. It's good for stopping fragmentation and 9mm rounds but pathetic against anything else. This is why soldiers use ceramic plates with their soft armour since they can easily withstand multiple shots from a 7.62 NATO round.
Ancient Korean made bullet proof vest with 13 layers of hemp cloth. 12 layers of fabric stopped the bullet, and they added one more layer for just in case. lightweight armor, but very hot in the summer.
Josh I believe most bullets back then were unjacketed lead, and rifles occasionally came with bullet casting molds, so soldiers could cast their own bullets (though this'd be back in the mid-19th century and before). IIRC Minie ball molds were distributed to some soldiers as well at the close of the US Civil War and later. I can imagine the Korean vests being effective against soft lead that could have bubbles or other inconsistencies being fired at lower pressures, but once high-pressure smokeless powder and FMJ rounds became common you really needed modern polyester aramid fibers to counter them. Also, gotta wonder if modern ceramic plates could be lightened up by doing a ceramic/metal/carbon fiber multilayered sandwich plate like modern tanks sport.
Technically if some perishable items expires it looses its effect of what its suppose to do and not necessarily become poisonous. So in my opinion poison when expires would become less poisonous.
No, because rifle rounds existed for a long time. Soft body armor was always meant to stop handgun rounds. Hard steel plates aren't nearly as heavy and bulky as medieval armor. Hard ceramic plates are even lighter.
All soft vests are made up of a few dozen layers of armor fabric. These are generally good enough for bullets piercing through cover, ricocheting, or explosive fragmentation and shrapnel. They may also reduce injury from penetrating impacts.
Except for the problems. It's not actually that light, it weighs about 10lbs, with vests offering comparable protection (such as Dynema plates) being as light as 3 pounds per plate, or 6 pounds for both front and back protection. Furthermore, there have been problems with the adhesive used in assembly failing at higher temperatures (like the ones in the sandbox) causing the vest's protection to fail.
F1 cars have quite small engines, like you describe. But they need to be completely rebuilt after every race. Auto makers do not produce production cars with these engines as the frequency and cost of maintenance would be too high.
The bullet drawing leaving the gun was completely wrong. For many years I believed the bullet exited the gun with the casing attached. Only when I actually learned how a gun works (around 12 years old) did I understand it didn't. Just saying it might skew people's intuition.
+André Pereira Same here. I always wonder what makes those animators think the whole cartridge is going to be ejected from the barrel instead of just the bullet.
+Thilo Niewoehner Most of them are hippies who depend on government for everything. These are the same hippies who run for office and try to pass gun laws when they have no idea how they work.
From the question's point of view, it asks if a poison expires. This response doesn't really answer the question, unless you're trying to debate the difference between "less lethal" and "more lethal." Curing it doesn't stop the poison from being lethal, or what I should say, it alone is still going to kill you. Anti-toxins just prevent that from happening. Also, the venom you're referring to is a cytotoxin, specifically a cardiotoxin, but even that has a half life and can degrade over time.
a slow heavy bolet fired from sub machine gun can penetrate a standard steelplated armor. when a modern tank gets hit by a rocket or another tank shoting at it. its modern armor is raly a spaced armor with many layers ofcompost plating and some other materials. its a bit like you need to shoot at the same exact spot twice. me like. :)
I'm surprised you didn't touch on Dragon Skin body armour James... A very light, practical and flexible alternative to the current systems our military uses.
This video didn't REALLY explain HOW bulletproof vests WORK... It was more of a history lesson on how armor got heavy and had to be made lighter, and that it now has become heavier again :/
Koreans in 1860s. Nope. Mongols in 13th and 14th century. They used cloth layers to stop arrows passing into the body. What is more, they used a layer of silk so that if the cloth layers failed, the silk would wrap around the arrow and make it both easier to remove from the body and create a sterile layer to prevent infection from whatever nasties were on the arrow itself; for example, faeces. There are likely much older examples.
depends on some, wine tastes better when aged, so some poisons are more effected the older they are, but some have chemicals or something that eventually wear off.
Because it wouldn't dissipate the energy of the bullet enough, its like the difference between getting hit with a large heavy skillet, and a sack of flour, or something softer
Some poisons don't kill, some can be slow & agonising & some quicker. Some of the slower ones can be cured before death or serious ailments occur. Theres a certain snake venom that has a deadlier effect on the heart, than the wound.
I know cartoon are not suppose to be realistic but somehow it really annoys me how everytime they show a bullet being fired, the bullet is still attached to his case.
Joshua Latham Further back than what, the Roman Empire? Japan didn't even have writing at that point, so we don't really know about Japanese soldiers at that time, no?
Bullet proof vests are now made of Kevlar. Where as before they were made of metal plate sheets inserted into the vest. Kevlar is just the modern small arms resistant replacement.
There are types of "armor" kevlar and plated. Kevlar is usually what a civilian or police officer would use, and it's a material (a fiber I believe) that stops pretty much any handgun bullets (except maybe revolver). A metal plated armor is what they wear in the military (probably over kevlar incase of Penetration), the plates can stop assault rifle rounds and the better the plate, the higher rounds it fan take.
Ballistic armor has multiple ratings as to what it can stop. Levels I, IIA, II, and IIIA are typically Kevlar soft armor and can stop handgun ammunition due to the relatively low velocity. However, Levels III and IV are typically steel or ceramic plates and can stop high velocity rifle rounds some even armor piercing ammunition. Level III can stop up to 7.62 NATO armor piercing and level IV can stop up to .30-06 armor piercing.
Noscoping egg Mind you, a round doesn't have to go through you to deal damage.. In fact, if a round hits you the kinetic energy would still be delivered to your body i.e. it will hurt.
Q. How many G's did the luner landers pull when they left the moon? Q. The moon has 1/6 the gravity of earth so, at = acceleration on the moon and earth would the G force be the same or 1/6 that of earth? That is if we actually went there?
There would be no war at all. There would be no anything. No curiosity, no jealousy, or greed. There would be no happy, sad, love, hate, friends, family, etc. Unless we were born programmed to do a certain task, we would do nothing. Nothing at all.
