Why don't soldiers wear a totally bullet proof suit which would cover from head to feet?
First off, if you wear totally bullet proof suit which would cover you from head to feet, it may save you from a rifle or a pistol, but it won't certainly save you from this:and definitely not this:also, most body armour is fire resistant, but not fire proof, and I can bet you all my money from my piggy bank which isn't even a pig but a tiger, that body armour, even the most advanced versions, would not save you from a military flame thrower.Current body armour is also usually made from two types of materials called Kevlar and ceramics. Once the ceramics have been hit, the vest becomes mostly useless very rapidly. Kevlar doesn't usually have that problem, but it can't stop anything better than a standard gun with any real success.If full body armour were a thing, you'd be running around in a combat situation with several hundred pounds of extra gear that became useless after the first time you were hit with a 7.62 (the AK47, which is the most common rifle in the world, is 7.62) This body armour would just be a terrible waste of resources and weight.Soldiers need to minimise their carry weight, especially in combat. The gear they wear already weighs around 80 pounds, adding to that would reduce combat efficiency, and make them easy targets for snipers and such.So in other words, like the many people who already answered this question, the two main reasons soldiers around the world don't wear armour like that of the star wars stormtroopers or the video game fallout 4 power armour is because it is heavy, and doesn't really protect the soldier that much from explosions our flamethrowers, or any other type of weapons apart from rifles.
If you could build a humanoid robot to protect you, what weaponry and defenses would you install within it?
Okay. Lets begin with humanoid robot. Which is an android. My favorite android to this day (even knowing he would get his butt kicked by most other androids) is Sony, from I, Robot. Now, Sony is nowhere near fit for a battle android. Sony got hurt by a bullet. However, Sony is very strong. A single NS5 can drag around a car with one hand easily. Sony jumped from a building, and landed like nothing, even after being shot in the leg. Heck, Sony might even be stronger than Chappie (although probably not stronger than Terminator) considering he nails his fingers into concrete and climbs walls like Spiderman..Speaking of Spiderman, where NS5 really shine is in their agility. I mean, the things literally move like freakin Spiderman. NS5 are the most agile androids I’ve seen (in live action movies). But it gets better. A single NS5 can swing around a pole like a gymnast holding on with just one hand, even with the added weight of Will Smith. Will Smith weights 180lbs. For you to have an idea, a bomb suit weights more than 75lbs. Which means, Sony could wear two bomb suits, and still be as agile. But of course, I wouldn’t armor Sony with two bomb suits. I would just armor him with the most indestructible material and shock absorbant and radiation resistant technology. To make him immune to EMPs and stuff. And force fields that melt polymer arms. And acid, and whatever else..Weaponry, I would use weapons in containers and places only the android could access. But the locks would be physical, not technological. And would build in the android a tool to open it. Also, holsters in the legs for plasma guns, rail guns, particle accelerator guns, or whatever. And some non lethal weapons too. And maybe build rockets into it to give it the ability to fly like Ironman. In fact, if we put Ironman, then just put Sony in a modified Ironman suit. Those are basically everything proof and well weaponized. But modified to match Sony’s agility. And maybe even turn Sony into the suit itself. I would add grappling hooks and, Ironman’s beams take a second or two to charge before they shoot. I need something just as powerful and fast as a bullet. Like Predator’s plasma cannons. But the plasma balls travel too slow. Also need non lethal weapons..So, an Ironman suit turned android adapted to Sony’s agility, capable of shooting plasma balls at the speed of bullets, with grappling hook, and non lethal weapons. And a few more tweeks if necessary.
Could you survive a tiger attack if you were in a full suit of medieval armor?
Tigers aren’t dumb. They would inherently be scared by the clanking steel because it isn’t anything like their prey items. In medieval armor you would never even catch a glimpse of a wild tiger. Even a tame one is likely to steer clear of you.The situation would be different if you cornered a tiger in a confined space and provoked it. There is no doubt that it would signal its anger and then suddenly attack. The attack of any big cat is fast and uses a combination of hard strikes with the paws and deep bites with long canines. Small prey (like humans) is easily dispatched by biting through the skull. For killing large prey the usual technique is to bite the throat, crushing the windpipe and causing suffocation.How would medieval armor fare?A tiger can very easily bite through an unprotected human skull. Really no contest. However the size of the steel helmet is a bit to large for the tigers jaws. This means that the tiger is likely to attack the throat. The armor is designed to absorb the energy of projectiles but it is not designed to withstand any pulling or ripping force. Remember that the steel helmet is fitted over the human head and is really only held on by gravity.The tiger attack would go something like this:After aggressive posturing the tiger would very suddenly choose its moment and attack.The attack would attempt to strike by surprise from the rear with maximum momentum. This blow would temporarily stun the person in the armor, making them unable to counter the attack.The tiger would immediately pin its victim to the ground and get a grip on the neck with its canines. At this point the tiger would realize that the armor is loosely attached to the innards and would rip it by pushing down with its paws and ripping upwards with its jaws.The nice juicy human head would be revealed and for the tiger it would be dinner time.Don’t mess with the big cats. They are stronger than you and even if hand-reared they are never completely tame.
What consist of a bullet proof glass/armor & metal
The "bullet proof" characteristic of different materials depends on what kind of bullet you are talking about. It gets down to the ability of the material to absorb locallized kinetic energy. From physics, the kinetic energy of a moving object is 1/2 mv^2. To stop a bullet, that kinetic energy must be absorbed in a manner that protects what is behind it. A nice thick piece of good tough steel will stop anything (if it is thick enough) but it will be too heavy to move or see through. For body armor (which is only able to stop relatively small bullets), the bullet proof materials are typically ceramic composites that specially formulated, processed, and fabricated. There are different designs but one approach is a hard ceramic outer shell which breaks the bullet into small pieces (so each piece has much less kinetic energy) and then tough material underneath which absorbs a lot of energy as it breaks. This way the pieces of the bullet are stopped before they get to the body and the result of the impact does not do serious damage (although the body will probably be bruised and could have a broken bone, depending one where it hit). Of course, once the bullet proof vest has taken a hit in one spot, that spot is now damaged and another hit in the same spot may get thru. Lots of strange things happen when you are dealing with materials interacting at very high speeds. Materials do not behave the same way they do if the forces are applied slowly. hope this helps
Free fall impact survival suit?
I was thinking about how many people have survived free falls while sky diving and how many more have been killed by parachute malfunctions, and I got wondering if it might be possible to design a suit that would protect people from the forceful ground impact after a failed sky diving attempt. My idea is basically to have a suit with a hard/armored exoskeleton of molded kevlar or ceramic or possibly titanium with padding on the inside; basically, inside there would be two layers of padding--one layer of medium to light density foam and one layer of higher density foam. Additionally, the boots of the suit could have springs and/or shock absorbers built into them to provide addtional time to decelerate if the person can manage to land on their feet I am not sure how much protection this would provide or if it would be any useful amount. However, if this could be developed into a functional device then it could save a lot of people's lives. Just give me your guys' feedback and ideas and refinements of the design. Ideally, the suit would completely protect the wearer from any serious injury all alone but remember most failed sky diving attempts are when the parachute has, at least minimally deployed but is tangled so you might have something like 20 or 30 square feet to slow you down. My goal would be that this 20 or 30 square feet plus the suit would significantly raise the odds of survival for a sky diver whose parachute malfunctions. Thanks in advance for all your ideas and constructive criticisms! :) most helpful answer gets the points!
Why doesn't Batman make an armored suit like Iron Man's?
Batman, being the genius he is, has designed powered exoskeletons before. In fact, he’s designed dozens.Among his most famous are the Anti-Nuke Batsuit…Source: Batman and Robin #12The Batman Beyond Batsuit…Source: Batman #18The Thrasher Batsuit…Source: Batman Night of the OwlsThe Justice Buster Batsuit…Source: Batman EndgameAnd, greatest of all, the Hell-Bat — the suit that took down Darkseid himself…Source: Batman and Robin #33Yet, unlike Iron Man, Batman prefers to reserve his “power suits” for only the most extreme of circumstances.Batman is a detective. A vigilante. Purging Gotham’s plague of crime is his primary concern. He generally faces off against grounded threats — gang-leaders, corrupt politicians, psychopaths, and accidents of science. As such, his methods are more tempered than that of his superpowered peers. His methods need to be, in order to keep himself from accidentally killing somebody. To keep himself from beckoning something worse.“We start carrying semi-automatics, they buy automatics. We start wearing Kevlar, they buy armor piercing rounds.” — Batman BeginsFurthermore, Batman is most comfortable when operating from the shadows. He can think three steps ahead, set traps, pinpoint weaknesses, and strike when his opponents least expect it. While it may be tempting to utilize the muscle of a power-armor, overreliance on such muscle would dull Batman’s cunning. Additionally, one can’t work swiftly or stealthily in a clanking, clunky suit.All of that said, there are certain occasions when Batman has no other option — when he’s hopelessly outclassed. On those occasions? Batman’s arsenal of armors will be there, ready to dish out justice.Source: Batman and Robin #33
How do soldiers die in war despite wearing body armour?
This is the extent of hard body armor coverage.The vital organs, mainly.Say you get shot in a place where you have no plate, for example the femoral artery near your groin and you don’t have a groin flap. You may bleed out and die.Or, say you get shot in the armor enough that it fails. Ceramic metal plates are good, but only take so much before they fail. And when they do, they will not protect you further.And guns and bullets are not the sole item in war. That kind of armor may not protect against some forms of shrapnel and definitely won’t defend much against an explosion such as a grenade.Say a grenade detonates near you. Sure, your hard plate stops some shrapnel, but other bits embed in the unarmored bits of you. One nicks an important artery and you bleed out and die.Body armor isn’t a magic cure-all. The plate carriers, soft vests that hold those hard ceramic plates, will only offer protection from pistol ammo such as 9mm or .45, not larger rifle rounds such as from a Kalashnikov rifle. And this is if the plate carrier has kevlar inserts. Some newer and lighter carriers have no such kevlar padding, sacrificing protection in favor of speed and mobility.Other than a helmet and the body armor, there isn’t much additional protection.Not to mention, that armor won’t protect you if, say, you fall off a six story building and break your neck, or if you get shot and live but die from infection.Body armor will not protect against chemical and radiation attacks either. MOPP suits can offer this protection, however, but they aren’t body armor.And to offer protection, you must wear it as well. Sometimes, soldiers would ditch the hard metal plates and just wear the vests, or only keep the front plate. The desert is hot. Running around with that hefty stuff can get tiresome.And surprise attacks. Random mortar bombings that hit well inside “safe” zones where people don’t wear armor and stuff like that.War is not just fought with men and guns. War also has other implements of terror, and those can be used as effectively as a gun.
