Everyone looked at Zhang Hao, and from time to time glanced at Zhang Shengye next to them. Speaking of which, asking others about the principles of weapons is a bit too much. But everyone was really shocked.
Especially the crossbow arrow, without tail feathers, can still move straight forward, which is a bit beyond everyone's understanding.
Zhang Hao smiled: "Uncle Zheng, thisit's not convenient to say for the time being. Please forgive me."
Disappointment flashed in everyone¡¯s eyes.
Zheng Changqiu apologized with a smile.
Zhang Hao did not want to continue: "When we discuss it later, the Zhang family will definitely tell everyone the truth."
Everyone¡¯s eyes lit up immediately, but then they looked at each other, and everyone saw the vigilance in their eyes.
The hidden meaning of Zhang Hao¡¯s words is obvious: Unless my Zhang family becomes a member of the Weapon Refining Guild, we will never let go of the eagle in sight!
The reason why Zhang Hao and Zhang Shengye did not hesitate to take out the best crossbow bed at home was to use it as a stepping stone.
Zheng Changqiu laughed a few times, looked at some complex large and small iron circles next to him and asked, "What is this?"
"Thisthis is a bearing!"
"Bearing?" Zheng Changqiu picked up one and looked at it, and finally his eyes were full of surprise, "It is really a bearing, but the bearing can hardly feel any resistance!
Dear nephew, what can you say about this bearing? "
Zhang Hao smiled and said: "This is what our craftsmen figured out when they were bored.
?Compared with those simple slip ring bearings, this kind of roller bearing barely feels any obvious resistance.
The most important thing is that such bearings are relatively easy to replace. If the bearing is damaged, there is no need to overhaul it, just replace it with a new bearing. "
Everyone picked up a bearing and observed it, and gradually their faces became serious. Only by careful observation can you find that this small bearing is anything but simple.
Zhang Hao looked on with a smile.
Don¡¯t underestimate this small component!
Without bearings, there would be no country on wheels, no high-speed and stable rotating industrial machinery, and no industrial power.
Bearings are the joints of industry!
In this world, bearings now have many applications. Vehicles, crossbow beds, city wall hanging doors, etc.
If the crossbow bed is the stepping stone for the Zhang family to enter the Weapon Refining Guild, then the bearing is an important product that the Zhang family plans to sell to the Weapon Refining Guild. It will also be Zhangjia¡¯s flagship product in the future, and it will be sold at home and abroad!
If you want to produce bearings, it is almost impossible without machine tools. It is not impossible to polish it by hand, it will definitely make the craftsmen doubt their life.
However, Zhang Hao also understands that one should not underestimate the wisdom of this world; simple machine tools are not complicated, and it is unlikely that they will be developed soon.
But before everyone develops machine tools, it will be enough for the Zhang family to make a huge fortune relying on bearings. By then, the Zhang family will be able to engage in a price war and severely suppress their opponents!
Now, everyone is looking at these precision bearings in amazement.
Someone finally said: "This bearing technology alone is enough for the Zhang family to become a member of the Weapon Refining Guild."
Everybody was talking about it.
After a long time, Zhang Hao took the initiative to interrupt everyone's discussion, pointed to the third set of items, and introduced loudly: "This is a gift from the Zhang family to the Weapon Refining Guild."
Everyone was a little confused looking at the neatly arranged and various items. Judging from Zhang Hao's tone, it seems that these are great things. But why does it look like an ordinary item?
Someone went over to identify it: "The purity of black iron is 62%? Mr. Zhang, are you sure this is a gift to the Weapon Refining Guild?"
Zhang Hao glanced at the other party with contempt and said loudly: "This gift is called: Standard!"
Zhang Hao looked around and started to introduce directly.
"Many people wonder why the Zhang family can produce thousands of tons of black iron a month! Today, I will tell you a reason, and that is - standards!
What is a standard? "
Zhang Hao didn¡¯t say anything, and directly disassembled several identical bearings on site. The base, rollers, cages, and screws rolled all over the floor. Then, Zhang Hao randomly selected them and slowly reassembled the bearing.
Gently pushing the bearing in front of everyone, Zhang Hao said quietly: "This is the standard!"
Everyone¡¯s eyes froze. Sometimes, a thousand words are worth less than an action.
"Everyone makes their own weapons and so on. There is not even a hair on the standard."??It's not too late to keep it secret. Even within some families, the standards for magic weapons and magic weapons are different!
Zheng Changqiu is a pragmatic person. He squatted down, picked up the screwdriver on the ground, and began to disassemble and assemble the bearings. He disassembled it very carefully and looked at every part.
With Zheng Changqiu as an example, even Mu Yingying and Mei Qianyun started to disassemble and assemble the bearings after taking a look at it.
????????Compare every roller, compare every screw
It was noon before I knew it. Zhang Hao clapped his hands, and the Zhang family's cooks immediately delivered a simple lunch.
Everyone took a few bites and then continued to disassemble and assemble the bearings. By mid-afternoon, Mei Qianyun, a fairy, had oil stains on her sleeves.
"Zhang Hao didn't say anything after that. He asked the guard to lay down a piece of paper on the wooden board. He picked up the attack on the table and started drawing.
"This is called a 'meter ruler'. In order to refine production, we have adopted a unit that is smaller and simpler than the 'foot and foot', which we internally named 'meter' and 'centimeter' in our Zhang family.
The traditional units such as ¡®Zhang, Chi¡¯ are relatively confusing and the units are large, which is not conducive to refined production. "
"This is a compass. Using a compass, I can easily draw countless identical circles."
"This is a protractor. We divide the circumference into 360 scales. Each scale is called a 'degree'. Each scale is temporarily divided into 60 minutes."
"This is a clock. We divide it into hours, one hour and 60 minutes, and one minute and 60 seconds. The division standard of the circle is based on the clock."
"This is a thermometer. We set the ice-water meter as zero degrees, set the temperature of boiling water at sea level as 100 degrees, and divide it into 100 equal scales in the middle. Then rely on this standard to extend upward or downward.
Using a thermometer, we can visually express the temperature. "
"This is a scale, this is a balance We have adopted a new unit: kilogram, one kilogram is one kilogram"
¡¡
This was a wonderful performance. Zhang Hao kept talking for more than an hour, and finally even proposed a ¡®combination unit¡¯.
For example: acceleration, pressure, etc.
But Zhang Hao just clicked on all the combined units, but he didn't talk about the meaning of combined units. But it also left an introduction and a seed.
Finally, Zhang Hao concluded: "Since we want to build war magic weapons together, standards are very important. Only unified standards can achieve perfect fit between each magic weapon.
This ¡®standard¡¯ is the Zhang family¡¯s gift to the Weapon Refining Guild! "
The applause sounded in pieces at first, but soon it became loud and continuous like ocean waves.
The so-called sword is given to the martyrs; the ¡®standard¡¯ is the ¡®sword¡¯ that these weapon-making guilds need. Its preciousness is far beyond the measure of wealth.
The birth of standards has allowed everyone to see a different world!
Amid the applause, Ji BuTong of Jiuyang Sect shouted: "I agree with the Zhang family joining the Weapon Refining Guild!"
