What does it mean to say that a person works with a steel helmet on his head?

It is the meaning of the head of the bar, and the steel helmet is the meaning of the iron head, which refers to the work more seriously, without any doubts and problems. This refers to the love of raising the bar,

Serious and willful, meticulous in his work.

This is you heard it wrong, not a steel helmet.

It is the fate of the "burly gang".

This refers to the combination of the stem and branch on a person's birthday is the day of the Kuigang.

Kui Gang is a divine term in numerology, representing characteristics such as strength, paranoia, and neutrality.

Generally, women are born with burly, and they all say that she has a strong personality, has a strong family after marriage, and has the initiative and voice at home.

In traditional culture, women generally regard weakness as beauty, so they think that burly girls are not suitable, and now the times are changing, men and women tend to balance their careers and abilities, and there are more and more strong women, so burly men are not so obviously bad.

Pay attention to reconciling your temper and soften your personality moderately. This is a very normal phenomenon.

The original role of the steel helmet was to protect against shrapnel from bombs or shells.

Blown into the head.

Deals fatal damage.

So the greater the role of the surface area, the better.

Of course, in the case of satisfying protection.

The lighter, the better. As for why the helmet is spherical.

The main thing is that the human head is spherical.

Let's not forget that helmets were invented very early.

Most likely, the designers would not have thought of changing the trajectory of the bullet.

Besides, it's not a hit in the head, it's still dead, how can there be so much attention.

Thought it was a previous casting tank.

Even the current tanks have become square.

The main lethal factor on the battlefield is not bullets, and bullets do not have an advantage in the total number of injuries. In World War II, 75% of the personnel were caused by various objects, 72% were caused by fragments in the Gulf War, and only 20% were guns, and 91% were caused by fragments in the Korean WarThe helmet is to protect personnel from the damage of fragments.

Of course it works! Under normal circumstances, the bullet does not easily pass through the steel helmet, because the steel helmet is hemispherical, except for very accurate frontal shooting, otherwise the bullet and the like are only pulled by the spherical surface**.

Since the helmet has a certain curvature, it can change the direction of bullets flying from slightly off the road. If the bullet is forward, the bullet will pass through the helmet and through the head.

The steel helmet is round, I wonder if you noticed? , that's to make the bullet "jump" off. It is to make a certain probability of bullets not hitting people with helmets, not to prevent direct hits, and it is not enough to prevent direct hits. Hehe.

Prevent shrapnel from hitting a person's brain.

Almost, there are many uses. 2. During the war, the U.S. Army was the first to start using it. It can be hung on objects to prevent it from falling. It can also be plugged into a tree branch for camouflage.

Monkey KingMonkey King is the title of Monkey King in "Journey to the West", and the two corners of Sun Wukong's headdress are like a curved bow.

This is the famous "magic stick"!

This is mainly because their steel helmets are not easy to use and do not protect their lives well. Although the military industry departments of various countries have developed a variety of helmets for their soldiers according to the actual situation on the battlefield, due to the generally low technology at that time, there are still many drawbacks in the production of steel helmets, not to mention that they do not play a good protective role, and often drag down the soldiers. Therefore, many veterans dissuade recruits from wearing steel helmets to the battlefield.

First of all, the weight of the steel helmet is a burden for many soldiers. At that time, the scientific and technological level of the whole world was relatively low, and no new materials were developed, so the materials of steel helmets were basically steel. The specific gravity of steel is relatively large, so the weight of a steel helmet is generally 3-4 kg.

Just imagine, a person with a steel helmet weighing seven or eight pounds on his head will cause a lot of pressure on the soldier's neck, whether he turns his head to observe or performs tactical sports.

The second reason is that the steel helmet cannot effectively block bullets, and can only resist the damage of some stray bullets and gravel. The steel helmet that can withstand bullets weighs more than ten or twenty pounds, which is not something that humans can bear. Therefore, the bullet can easily penetrate the steel helmet and effectively kill the soldier's head.

In other words, the soldiers wore steel helmets only to withstand stray bullets. But this kind of practice at the expense of flexibility is really not known to be promoted.

Another reason is that steel helmets are easy to reflect light, and they are also easy to rub against other objects to make a harsh sound. After all, in the early days, steel helmets were only sprayed with some paint, and the traces of soldiers would be exposed due to reflections in the sun and light. In addition, the steel helmet is relatively hard, and the sound is harsh when rubbing against tree branches, sand and gravel and other objects, which is not conducive to the camouflage and concealment of soldiers at all.

Therefore, it still makes sense for veterans to persuade recruits to go to the battlefield without helmets.

It is not uncommon for soldiers wearing helmets to be shot in the head during combat, while soldiers without helmets do not have such a high mortality rate. This is something that many new recruits who have just entered the battlefield do not know.

Newcomers will be uncomfortable at first, if they wear a steel helmet to the battlefield, they may not be very flexible, and it is also relatively bulky, so they will be advised not to wear a steel helmet first.

I think it's because the steel helmet is too heavy, and some recruits may not be very good in physical fitness, if wearing a steel helmet is just a burden, it may become your fatal trouble, and on the battlefield, the fatal place is not only the head.

Wearing a helmet greatly limits flexibility. Twisting the neck is very inflexible, which seriously hinders battlefield observation. And the helmet was too heavy, and the physical exertion of the soldier was serious. Even if the helmet is hit by a bullet, the neck will not be able to withstand the impact of the bullet.
