Chapter 79 Standards
Everyone looked at Zhang Hao, and glanced at Zhang Shengye next to him from time to time. Speaking of which, asking about the principle of other people's weapons is a bit too much. But everyone was really shocked.
Especially the crossbow bolt, without tail feathers, can still move straight forward, which is a bit beyond everyone's perception.
Zhang Hao smiled: "Uncle Zheng, this...it's not convenient to talk about it for now. Please forgive me."
Disappointment flashed in everyone's eyes.
Zheng Changqiu smiled and apologized.
I don't want Zhang Hao 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 they all saw the vigilance in their eyes.
The underlying meaning of Zhang Hao's words is obvious: Unless my Zhang family becomes a member of the Artifact Refining Guild, we won't see rabbits or hawks!
The reason why Zhang Hao and Zhang Shengye did not hesitate to take out the best crossbow bed at home was to serve as a stepping stone.
Zheng Changqiu laughed a few times, looked at some large and small complicated iron circles beside him and asked, "What is this?"
"This... this is a bearing!"
"Bearing?" Zheng Changqiu picked up one and looked at it, and finally his eyes were full of surprise, "It's really a bearing, but the bearing hardly feels any resistance!
Nephew, what can you say about this bearing? "
Zhang Hao said with a smile: "The artisans of our family groped for it when they were bored.
Compared with those simple slip ring bearings, this kind of roller bearings hardly feel obvious resistance.
The most important thing is that such bearing replacement is relatively convenient. In case the bearing is damaged, there is no need to overhaul it, just replace it with a new one. "
Everyone picked up a bearing to observe, and gradually, their expressions became serious. Only by careful observation can we find that this small bearing is by no means simple.
Zhang Hao watched with a smile on the side.
Don't underestimate this small component!
Without bearings, there would be no country on wheels, no high-speed and stable industrial machinery, and no industrial power.
Bearings are the joints of industry!
In this world, bearings also have many applications now. Vehicles, ballistas, portcullises and more.
If the crossbow bed is the stepping stone for the Zhang family to enter the Artifact Refining Guild, then the bearing is an important commodity that the Zhang family plans to sell to the Artifact Refining Guild. It will also be the flagship product of the Zhang family in the future, and it will be sold both at home and abroad!
It is almost impossible to produce bearings without machine tools. It is not impossible to polish by hand, and it will definitely make craftsmen doubt life.
But Zhang Hao also understands, don't underestimate the wisdom of this world; simple machine tools are not complicated, and they may be researched soon.
But before everyone researched the machine tool, it was enough for the Zhang family to earn a huge fortune relying on bearings. At that time, the Zhang family will be able to play price wars and severely suppress their opponents!
But right now, everyone was amazed at these precise bearings.
Finally someone said: "This bearing technology alone is enough for the Zhang family to become a member of the Artifact Refining Guild."
Everyone talked about it.
After a long time, Zhang Hao took the initiative to interrupt everyone's discussion, pointed to the third group of items, and introduced loudly: "This is a gift from the Zhang family to the Artifact Refining Guild."
Everyone looked at the neatly arranged and various items, a little confused. Judging from Zhang Hao's tone, it seems that these are very remarkable things. But why does it look like an ordinary item?
Someone went over to appraise it: "The purity of black iron is 62%? Mr. Zhang, are you sure this is a gift for the Refining Guild?"
Zhang Hao glanced at the other party with contempt, and said loudly: "This gift is called: Standard!"
Zhang Hao looked around and introduced directly.
"Many people wonder why the Zhang family can produce thousands of tons of black iron in a month! Today, I will tell you one reason, and that is - standard!
What is a standard? "
Without saying a word, Zhang Hao directly disassembled several identical bearings on the spot, and the base, rollers, cages, and screws rolled all over the floor. Then, Zhang Hao randomly selected them, and slowly rebuilt 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 an action.
Everyone refines utensils, etc., each refines its own, and there is not even a single hair in the standard. It's too late to keep it secret. Even within some families, the standards for magic weapons and instruments are different!
Zheng Changqiu is a pragmatic person. He squatted down, picked up the screwdriver on the ground, and began to disassemble and install the bearings. He disassembled very carefully and carefully observed every part.
With Zheng Changqiu as an example, even Mu Yingying and Mei Qianyun took a look at it before starting to disassemble and install the bearings.
Everyone compares each roller, compares each screw...
Before I knew it, it was noon. Zhang Hao clapped his hands, and the chefs of the Zhang family immediately delivered a simple lunch.
Everyone ate a few mouthfuls casually, and then continued to disassemble and assemble the bearing. In the middle of the afternoon, Mei Qianyun, a fairy, had oil stains on her sleeves.
Then Zhang Hao still didn't speak, he asked the guard to lay a piece of paper on the wooden board, he picked up the attack on the table, and started drawing.
"This is called 'meter ruler'. In order to refine production, we have adopted a smaller and simpler unit than 'zhang and ruler'. Our Zhang family internally named it 'meter' and 'centimeter'.
Traditional units such as "zhang and chi" are relatively chaotic, and the units are relatively large, which is not conducive to refined production. "
"This is a compass. Using compasses, 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 division is temporarily divided into 60 points."
"This is a clock. We divide it into hours, 60 minutes in an hour, and 60 seconds in a minute. The division standard of the circle is borrowed from the clock."
"This is a thermometer. We set the ice water gauge at zero degrees, set the temperature of boiling water at sea level as 100 degrees, and divide it into 100 scales in the middle. Then rely on this standard to extend upwards or downwards.
Using a thermometer, we can visually indicate the temperature. "
"This is a scale, this is a balance... We have adopted a new unit: the kilogram, and a kilogram is a kilogram..."
...
It 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 for all the combined units, Zhang Hao just clicked and stopped, but he didn't say the meaning of the combined units. But also left an introduction, a seed.
In the end, Zhang Hao concluded: "Since we want to build war magic weapons together, standards are very important. Only with unified standards can we achieve a perfect fit between the magic weapons and weapons.
This 'standard' is a congratulatory gift from the Zhang family to the Artifact Refining Guild! "
The applause was sporadic at first, but soon became louder and louder, continuous like ocean waves.
The so-called swords are given to martyrs; the 'standard' is the 'sword' that these refining guilds need, and its preciousness is far beyond the measure of wealth.
The birth of the standard made everyone faintly see a different world!
Amidst the applause, Ji Different from Nine Yang Sect shouted: "I agree with the Zhang family joining the Artifact Refining Guild!"
