Daming: If I find a great-grandson, I will teach an emperor through the ages

Chapter 47 Vernier Calipers
"Bah-!"

"Bah-!"

"Bah-!"

The steam engine keeps running, but it always leaks air and pressure at the same place.

Cao Wei looked at Yan Zhen straight, and Yan Zhen looked at Cao Wei straight.

"Isn't it because the accuracy is not calculated, or there are errors in the parts when they are manufactured, as long as they are more careful." Cao Wei said.

It took him almost half a month to build a steam engine. Yan Zhen came back with that steam engine. In just a few days, he built another one. The efficiency has doubled, and the accuracy will have errors. normal.

But Yan Zhenzhi didn't think so. The workers and craftsmen in his Ministry of Industry were almost the best in the world.

Combining the efforts of all skilled craftsmen, working overtime day and night, but not being able to build a steam engine that meets the standards and runs smoothly, it really shouldn't be.

Cao Wei can find a few blacksmiths in the private sector to do something, and there is no reason why the staff of the Ministry of Industry can't do better!

But after the second steam engine was built, there was still a problem of air leakage.

Yan Zhenzhi couldn't accept it.

Moreover, on the other side, there was an order from Zhu Yuanzhang to produce a steam engine that could run smoothly as soon as possible, which could be regarded as a great contribution to the Ministry of Industry.

But if it is delayed for too long... the great success will be lost, and there may be errors of incompetence.

Who knows what Zhu Yuanzhang's standard for "as soon as possible" was in his heart. Yan Zhenzhi naturally wanted to build a steam engine that could run smoothly as soon as possible, the better.

So he thought of Cao Wei, the genius who was the first to design and build a steam engine.

Anyway, Cao Wei spends his days at home either fishing or hanging out, so he is just idle. He might as well come to the Ministry of Industry to shine and successfully build a steam engine as soon as possible.

Yan Zhenzhi rubbed his hands and said with a smile:

"Brother Cao, although you say that, time is running out and His Majesty can't wait too long, and you have experience..."

He was half-spoken, but was stopped by Cao Wei's hand.

"It's you who are short on time, not me. I thought it was some kind of difficult problem to solve. It turned out that it was just a measurement and calculation of accuracy."

Cao Wei turned to look at the many workers from the Ministry of Industry, "You have so many people, as long as you let them be more serious, meticulous, and patient, maybe it will work."

"I'm still busy, so I'm sorry, so I'm leaving."

After finishing speaking, Cao Wei lifted his foot and walked out.

Does he know how troublesome it is to manufacture a steam engine, just measuring various data is a very painful and tormenting thing!

Whoever wants to do this job can do it, but he doesn’t want to do it anyway.

When Yan Zhen saw this, he became anxious instantly!If Cao Wei doesn't help him, the progress of the Ministry of Industry's development of steam engines will definitely be slowed down!
"Brother Cao, wait a minute. Your Majesty once told me that as long as you build a steam engine, it will be a great achievement. I will give half of the credit to you. Is this okay?" Yan Zhen pulled Cao Wei's sleeve and said pitifully .

However, Cao Wei was unmoved in the slightest.

He has less than a year to return to modern times, and no matter how great his achievements are, it will be of no use to him!

"Lao Yan, please stop pulling and tugging, it's not appropriate to look like this..." Cao Wei wanted to pull his sleeves back.

"You were also involved in the production of the steam engine back then. As long as you work hard, you will be able to succeed. Don't worry, Lao Zhu... His Majesty will definitely not blame you!"

"Besides, I've suffered a severe head injury in the past two days and my consciousness is not clear at all. I can't help you much..."

Cao Wei struggled for a long time, and finally pulled back his sleeve, and staggered.

Yan Zhenzhi probably saw Cao Wei's determination to leave, nodded and said:

"Okay, since that's the case, I won't force others to make things difficult for me. Brother Cao, please do as you please, and Yan will not send it away. I will write to His Majesty in a while, tell him about this matter, and ask him to give him a few days of grace... "

Cao Wei, who was walking out, slowed down when he heard this.

Submit a letter to Zhu Yuanzhang...

If Zhu Yuanzhang knew that he was not helping the Ministry of Industry, would he do something to him?
Once again, I recalled the way Zhu Yuanzhang looked at me when I pointed at Zhu Yuanzhang's nose.

Cao Wei feels that this possibility is very high...

Suddenly shivering, Cao Wei turned around and turned back.

"Your Majesty said that building a steam engine is a great achievement, so did you say what rewards will be given?" Cao Wei asked.

Yan Zhenzhi immediately understood, and said happily:
"Your Majesty didn't say this, but don't worry, little brother Cao, as long as we can successfully develop a steam engine, I will definitely report to Your Majesty and give you a big reward, which will definitely satisfy you!"

Cao Wei frowned, and shook his head righteously:

"What did Brother Yan say? Since you have needs, how can I just sit idly by? Let's get the steam engine out first. As for the rewards, let's talk about it later..."

After finishing speaking, Cao Wei rolled up his sleeves, seeing that the posture was indeed about to do a big job.

"Saw this steam engine for me too! Then measure the corresponding data!"

"There is also the data measured by the previous steam engine. Take it out and let me take a look!"

Cao Wei unceremoniously directed the staff of the Ministry of Industry.

When they heard Cao Wei's words, they looked at Yan Zhenzhi speechlessly.

Naturally, Yan Zhenzhi couldn't offend Cao Wei, "Why are you still standing there? Just do what little brother Cao says! From now on, when you see little brother Cao, it's like meeting me, and what he says is like What I said! Do you understand?"

After Yan Zhenzhi finished speaking, a group of workers from the Ministry of Industry got busy, picked up the hacksaw and cut the steam engine, sparking a burst of sparks...

Someone on the other side had already brought over all the measurement data of the previous steam engine and presented it to Cao Wei.

An hour later, the harsh sound of the hacksaw finally disappeared, and the steam engine was cut in half.

Following Cao Wei's instructions, a group of staff began to measure various data of the steam engine again.

Cao Wei watched them working in a hurry, but the efficiency was really not high.

They were measuring everywhere with rulers, but the progress was too slow!

Just like when he measured whether the diameters of the pistons were equal, he needed to move the ruler bit by bit to measure, which was too time-consuming and laborious.

suddenly,

Cao Wei thought of a modern measuring tool. When measuring, it is much more efficient than an ordinary scale, and it is also very convenient and quick to operate.

That's the vernier caliper.

Immediately, Cao Wei asked someone to find a pen and paper, and started drawing again, drawing the general appearance of the vernier caliper, its component composition, and working principle.

Yan Zhen looked down for a long time, "Is this a ruler? Why does it have such a strange shape?"

Cao Wei despised him at first.

Huh, Minister of the Ministry of Industry?No, you still don’t know as much as I do?
Then, pointing to the vernier caliper on the pattern, he explained its working principle to Yan Zhenzhi...

The latter was stunned for a moment, then widened his eyes and looked at Cao Wei.

The shock in his eyes was about to overflow!
