A nation's industrial development begins with junior engineers.

Jiang Xia first went to the newly built confidential workshop to check on the preparation work for the excavator components.

The current classified workshop is vastly different from the old small warehouse. It's much larger in area, and a gantry crane that Yang Youning brought from a restructured factory has been installed on the roof.

The workshop gate was also made extremely large, allowing large Yellow River trucks to drive smoothly into the workshop.

The 5MN hydraulic free forging machine sits in the corner of the workshop, and our level 8 welder is leading his apprentices and grand-apprentices to work on the excavator's boom.

It's so beautiful! The weld is seamless, and under the light, the fish-scale-like weld shimmers with iridescent colors.

"Xiao Jiang, this thing will be finished soldering in one more day, but it looks weird, what's it for?"

Liu Yongfu greeted Jiang Xia warmly.

"Hey, Master Liu, is our militia training still going on?"

Liu Yongfu was taken aback, a little unaccustomed to Jiang Xia's abrupt shifts in thought: "Hey! Don't even mention it. You haven't gone to the material yard yet, have you? They're still training to dig anti-tank ditches, it's exhausting!"

"Alright, in two days we'll show you what the King of the Trench really is!"

As he spoke, Jiang Xia walked over to Fan Jin, the former director of the water pump factory: "Engineer Fan, is there anything wrong with the hydraulic system?"

Fan Jin shook his head: "I guarantee there will be absolutely no problem with a single one like this, but we still need to assemble the hydraulic cylinders and such before we can see how it goes."

"Based on the control formula you provided, I've discovered that our device isn't reaching the predetermined values. See..."

As he spoke, Director Fan took out a hydraulic gauge and pointed to the value on the gauge.

"Here, towards the end of the process, the hydraulic oil pressure is consistently a little low..."

"Hey, don't get stuck in a dead end. The values ​​in the formula are just ideal conditions. The inner wall of our hydraulic cylinder isn't perfectly smooth. Getting hung up on those decimal points is useless. As long as it runs, that's fine!"

"You're right, aren't you, Engineer Wang?"

"Hehehe," the machine tool factory engineer surnamed Wang said, scratching the back of his head somewhat embarrassedly.

"Don't worry about it, don't worry about it. Your analysis report, Jiang, already woke me up."

"However, Engineer Jiang, come and take a look at the newly designed deep hole boring machine. The radial runout and axial movement of the spindle cannot still be controlled within a very small range."

"Oh?" Jiang Xia walked into the machine that had been disassembled into eight pieces.

Tsk, there's no need to turn on the scanner anymore. Jiang Xia's own knowledge is enough to handle the current situation.

"There's a problem with the bed and the uprights, Engineer Wang. You've mixed up the materials. The bed is still made of the old materials, but the uprights are made of the new alloy steel used for hydraulic columns, right?"

"While the stiffness of individual units may meet the requirements, the overall stiffness will definitely not be uniformly distributed!"

"So, Engineer Wang, have you ever heard of finite element analysis?"

Engineer Wang shook his head rapidly.

Okay, this is still a unit analysis method that Dean Qian used on the Flying Egg. This method is simply top-notch for analyzing and optimizing structures.

Moreover, during the learning process, Jiang Xia also optimized this analytical method.

Unfortunately, Dean Qian and his colleagues are too busy, and this practical method hasn't spread yet. Also, while the computational load of this method is indeed quite large, the smaller the unit, the closer the conclusions are to reality.

Just like the four-cylinder engine blueprints that Little Dumb Hair just made, the cylinder block was designed using this theory. After all, with "Big Yellow's" help, the amount of calculation required was extremely small compared to that of a laser gyroscope.

Let the little one be the knowledge carrier then, after all, the method is the method. What needs to be kept secret is only the answer obtained through this method.

Just like how every elementary school student has a dictionary, you can't say that an elementary school student's essay is plagiarized simply because you can find the same characters in the dictionary.

Little Hairy Hair Classroom is in session again!

The research object is discretized, and for each small unit, based on the fundamental laws of physics, the relationship between unknown quantities such as displacement, temperature, stress and strain of the nodes within the unit and external loads and boundary conditions is determined.

Then piece them together and analyze the relationships between each part.

Finally, based on these results, the rationality of the design is evaluated, and it is determined whether the structure meets the requirements for strength, stiffness, and stability, providing a basis for optimizing the design.

The number of people is increasing.

Teacher Zhu and his students, the designers of the "63" gun, and senior engineers from the Ministry of Petroleum, filled this classified workshop to the brim.

Even Ziyou Tuan, who has been busy since birth, stopped his work, breathing softly, unwilling to disturb those who were studying diligently.

"Great! Excellent! This analytical method can not only provide excellent solutions to mechanics problems, but it can even simplify complex problems related to heat conduction using Fourier's law!"

Teacher Zhu, caught up in the excitement, waved his one arm and cheered loudly.

As he finished speaking, a burst of applause resounded throughout the workshop.

"Jiang, could you elaborate on the degree of decomposition of the load?"

"Jiang, the temperature boundary is represented by a system of equations, but the unknown values ​​at each node are too large. Can we perform approximate value calculations?"

After the applause subsided, a barrage of questions emerged, leaving the little boy somewhat overwhelmed.

Li Changfu took a sip of tea and walked leisurely to the front.

"Everyone! Quiet down! It's getting late! If we don't get to the cafeteria soon, there won't be any water left for washing dishes!"

"If I hear the Way in the morning, I can die content in the evening! We can go without food!"

A voice rang out from the crowd, causing everyone to burst into laughter.

Despite saying that, everyone suppressed their excitement upon seeing Jiang Xia panting heavily and watched him leave first, accompanied by Wang Kui. After all, Jiang Xia looked quite annoyed, given his pale face.

Then they left one by one in a line.

We should be understanding and considerate of each other. Everyone knows that lecturing is actually very tiring, especially when you don't have a loudspeaker and have to shout to lecture.

Putting ourselves in their shoes, we all felt bad that this good young man would get exhausted.

Teacher Zhu walked up to Li Changfu and whispered something in his ear.

"Publish a book?"

"Yes, I found that Comrade Jiang Xia's theory is already very complete, even though he said in his lecture that it was a plan proposed by Dean Qian."

"However, I have also seen Dean Qian's manuscripts. Engineer Jiang's ability to deepen the theory and apply it to specific projects shows that he has put in a lot of hard work. This knowledge system is definitely very useful!"

"Think about it, if we had used this analytical method to analyze all the detours we took before, their little tricks would have been exposed long ago!"

Makes sense!

Li Changfu tightened his grip on the teacup. Yes, if this method could really distinguish certain malicious pieces of knowledge, then it would be really useful!

"Teacher Zhu, Jiang Xia is very busy lately. Putting aside the 301 project that is about to be completed, it seems that he will also be busy with this for a while."

As he spoke, Li Changfu pointed to one of his thick, strong arms.

"We'll help!"

Senior engineers from the Ministry of Petroleum also joined the small circle of discussion. "Engineer Jiang can dictate, and then we will record it and compile it into a book!"

"Yes! This book belongs to Engineer Jiang and Dean Qian; neither of us will be credited!"

Listening to the discussion, Li Changfu almost squeezed his handprint into the teacup.

Founding a new school of thought? My little rascal is such a delight!
