Back to the 80s Machinery Factory

Chapter 422 Teacher, what do you think of my stick?

But unfortunately,
The small, inconspicuous parts have all been replaced long ago.

The problems now are all with large items.

Zuo Zhuo watched for a while before speaking up, "Director Chen, why don't you try wearing this pin?"

Pin?
Chen Luyang looked in the direction Zuo Zhuo was pointing.

A completely deformed pin lay across the side of the toolbox, bent like a twisted iron rod.

"Holy crap... how could someone drive like that!"

Chen Luyang couldn't help but click his tongue; a perfectly good pin had been stretched into a banana shape.

"It would be so much better if we had a camera. It would be so convenient to take a picture and bring it back."

Chen Luyang muttered to himself as he bent down, picked it up, and weighed it in his hand.

Although it is also a large iron rod, it weighs about the same as an iron bucket of water, making it much lighter and smaller than an trunnion.

It's not too difficult to tie it horizontally to the back seat as long as you ride slowly.

"It's him!"

Chen Luyang made the final decision, placing the pin at the back of the vehicle and quickly starting to tie the rope.

In no time, he had carefully secured all the scrap parts and pins, which were wrapped in a large cloth bag containing old newspapers, to the back seat.

By the time everything was finished, it was almost midnight.

Chen Luyang originally planned to ride her bike back to school that night, but it was too late.

He was carrying a large bag full of scrap parts, which was inconvenient and unsafe.

I slept for half the night at the repair shop.
The next day, before dawn, Chen Luyang, under the stars and moon, carried the scrap parts back to school.

I rode for nearly two hours in the cold wind. The axle and cloth bag on the back seat weighed several dozen kilograms, and felt as heavy as if I were carrying a piece of lead.

As Chen Luyang rode on, she felt her legs were so sore they didn't even belong to her anymore.

I got back to the dormitory just as dawn was breaking.

Chen Luyang chatted with the dormitory auntie who had just gotten up and washed, helping her fetch water and clean the first-floor corridor.

Finally, the older woman agreed to let him temporarily store the scrap parts and pins in the storage room on the first floor of the dormitory.

Otherwise, it would be exhausting for him to carry just a single pivot pin from the first floor to the fourth floor.

Back in her dorm, Chen Luyang quickly splashed some cold water on her face, changed into clean clothes, grabbed her backpack, rushed to the cafeteria to buy a steamed bun, and hurried to the classroom while munching on it.

As soon as she sat down, Chen Luyang slumped in the chair, her eyelids drooping from exhaustion.

"Wenwei, didn't you sleep last night?"

Gao Xiaolin was startled by Chen Luyang's dark circles and unshaven face.

Chen Luyang usually pays a lot of attention to her personal image.

Every time Gao Xiaolin saw Chen Luyang, he was always in good spirits and clean.

This is the first time I've ever seen you look so listless.

"I'm going to sleep." Chen Luyang yawned, too tired to even speak.

Chen Luyang slept for less than four hours last night.

This morning, I carried dozens of kilograms of spare parts and rode my bike for two hours back to school.

People are exhausted to the point of being mentally challenged.

If it weren't for the fact that I can't skip class!

If it weren't for Lian Yinghua's consistently kindness to him!!!
He must have skipped today's class and gone to his room for a good nap.

As soon as the school bell rang, the lively laughter and conversations in the classroom immediately quieted down.

Lian Yinghua walked in, looking refreshed and carrying a book.

Since Chen Luyang's handwritten lecture notes and weekly open classes came along, Lian Yinghua's courses have become much easier to teach!

To be honest, in all his years of teaching, this was the first time he had ever seen a student as diligent as Chen Luyang!

Originally, I just wanted him to translate one chapter per week, taking it slowly.

Little did they know that Chen Luyang's hand speed was astonishing.
In just a few days, Samuelson had already completed one-third of the translation.

This prompted even Yinghua and several other teachers to get restless. While revising and improving the manuscript, they also began submitting proposals to push forward the translation project.

only……

Isn't this child working too hard?
Halfway through her speech, Lian Yinghua couldn't help but glance at Chen Luyang once again.

Since the start of class, Chen Luyang has yawned six or seven times.

Even with his best efforts, he was still exhausted, his eyes were bloodshot, and his gaze was unfocused.

Several times, even Yinghua felt that Chen Luyang was so sleepy that his soul seemed to have flown away.

Finally, the bell rang, and the get out of class was over.

Chen Luyang couldn't hold on for even a second longer. With a "thud," her head drooped, and she fell asleep on the table.

hiss……

Teacher Lian saw this scene and frowned.

Recently, he heard from students that Chen Luyang spends all his time in the Department of Mechanics, except for attending classes in the Department of Economics and the Department of Philosophy.

He leaves early and returns late every day, studying courses from three different majors all by himself.

Although no teacher can accept students sleeping in class.

But at this moment, Lian Yinghua really wanted Chen Luyang to get a good night's sleep.

It's just a pity that as soon as the school bell rang,
Chen Luyang groggily raised her head, her eyes still unfocused, but her hand had already subconsciously picked up a pen and started taking notes.

Did they listen? Nobody knows.

But whatever is written on the blackboard, he will copy it down word for word.

In the end, even Yinghua admired Chen Luyang's perseverance!
After a long day of classes, the students packed up their things and left the classroom in twos and threes.

Chen Luyang was so sleepy she felt lightheaded, and was packing her schoolbag when she heard a voice from the podium:
"Chen Luyang, stay behind for a moment."

Ok? ? ?
Chen Luyang subconsciously looked up and saw Lian Yinghua waving at her.

He quickly picked up his schoolbag and walked over.

Lian Yinghua asked softly, "I heard you've been taking classes in the Mechanics Department again recently?"

Chen Luyang was instantly startled awake.

Even Yinghua knows that I skipped my advanced calculus class to audit classes in the mechanics department?!

However, even Yinghua clearly didn't know that!

He earnestly advised, "It's good to be ambitious, but you must act within your capabilities. Health is the foundation of everything."

"You're only a freshman, you have plenty of time to study, there's no rush."

"A person's energy is limited. If you try to learn everything from economics to philosophy to mechanics, you may not be able to master any of them."

Chen Luyang nodded: "I know the teacher cares about me, and I will definitely manage my time well."

Hearing him say that, Lian Yinghua nodded with satisfaction.

"By the way, there's no need to rush the manuscript translation. Just control your pace and don't tire yourself out."

As he spoke, his tone softened further:
"It's not that your recent manuscript translations are bad; they're excellent! Very solid!"

"But your main task at school is to study. This is your primary responsibility and you can't put your life on the wrong foot."

Chen Luyang looked at Lian Yinghua.

Her eyes were bloodshot, whether from lack of sleep or from being moved, and they were sparkling.

There was also a hint of guilt mixed in.

He translated Samuelson's manuscripts with great enthusiasm, not out of diligence or simply out of a passion for learning.

It was simply because he was broke. He had used all of his personal savings to fund the T616.

The money Wang Qingzhou transferred hasn't arrived in my account yet.

He could only translate a few more manuscripts to earn some extra pocket money.

Even if his starting point was realistic, hearing his teacher's words at that moment still warmed his heart.

"Thank you, Teacher Lian."

Lian Yinghua laughed: "There's no need to thank me. Just manage your time well, and if there's anything you can't handle, come to me anytime."

"Uh-huh!!"

……

Lijiao Building

Zhang Diancai turned onto the corridor from the second floor of the Science and Education Building, still carrying the research project form that had just been approved.

This should have been good news to advance the project, but his face was as dark as the bottom of a pot.

The "Fatigue Crack Modeling of Connectors" project, which our research group is responsible for, is about to enter its middle stage.

The algorithms and modeling tools are all in place, and the team is almost done with the work.

But the most crucial element is the actual samples of scrapped parts from service...

It's stuck!
They had already reached an agreement with a factory in the suburbs to provide a batch of connectors for actual service use.

Zhang Diancai even personally led his students to investigate. The samples were piled up like a small mountain, all of them were repaired pins, trunnions, spring washers, and hot-etched bolts.

But less than a week after I returned, they suddenly changed their tune.

The deputy factory director who initially agreed to cooperate was temporarily transferred to a "May Seventh Cadre School" for study.

The newly appointed factory manager refused to acknowledge the issue: "You want supplies, but how many tons of steel can you approve? Can you allocate equipment quotas for us?"

In the eyes of the production system, scientific research projects are neither political tasks nor can they generate output value.

We have to allocate supplies for nothing, and then we have to arrange for workers to record the load and damage.

Nobody wants to do this job.

Zhang Diancai made three trips to the factory office, only to be told by the production department that "the technical department needs to stamp it first."

When the head of the technical department heard that a detailed list was to be written, he didn't even show his face.

The security department remained firm, saying that the factory needed to study the matter of transferring equipment from outside, and that "not even bolts can be picked up casually."

He was so angry that he waited in the corridor of the technical department for three days before he finally managed to catch the person.

As a result, they were dismissed with the statement, "The factory committee hasn't studied it yet."

Even more exaggerated,
The first batch of "samples" that were promised to be delivered turned out to be just randomly picked up from the scrap metal pile in the factory's backyard!
Even the service life of the parts, the usage environment, and the replacement time were not indicated!

Enraged, Zhang Diancai slammed the rusted and cracked track part back onto the ground.

He just finished lecturing on the theory of material strength this morning.

I originally planned to take the bus directly at noon and go to the factory again.

To my surprise, as soon as I turned back into the office corridor, I saw someone standing at my door.

The morning sunlight slanted into the corridor.

In the backlight,
A tall young man stood ramrod straight, with a gleaming long metal rod beside him and a bulging tool bag slung across his shoulder.

The golden light swept diagonally across his shoulders, forehead, and cuffs, and the stick gleamed with a metallic sheen, making one's eyelids twitch.

Where did this Sun Wukong come from?

Zhang Diancai was startled, almost thinking that some lab student had come to block his way with metal objects.

Before he could speak, "Sun Wukong" walked over carrying his staff.

"Teacher Zhang~"

The young man grinned, showing his big teeth, and greeted him politely and warmly.

"Are you an economics student?"

"Yes, Teacher Zhang."

"Sun Wukong" stepped forward, laughing heartily.

"I am Chen Luyang. Last time I asked you to draw a picture, you said you had something to do and asked me to come another day, so here I am."

Zhang Diancai frowned slightly.

He's currently busy with several research projects and simply doesn't have time to draw industrial blueprints for standard parts for a student.

As for the "let's talk another day" comment from last time, it was just a polite remark.

Who knew Chen Luyang would show up again!
He's already in a bad mood!

Just as I was about to speak and kick him out,
With a loud clang, Chen Luyang swung the large iron bar in his hand!
Then came a thunderous roar:

"Teacher Zhang, please take a look at this."

Saying,

The incredibly brave Chen Luyang lifted the thick, banana-shaped pin forward with one hand and planted it right in front of Zhang Diancai.

With a "whoosh," the thing almost grazed the tip of Teacher Zhang's nose.

Zhang Diancai instinctively leaned back, his face turning pale with fright.

"Oh my god...!" Chen Luyang's eyelids twitched, and she quickly shrank back, frantically explaining:
"Teacher, I didn't mean to. It's just that the axle is too heavy, and I haven't even gotten a firm grip yet."

"This is the pin on the sanitation bureau's tow truck. The truck runs frequently, more than 30 times a day. It suddenly broke a couple of days ago. When we towed it back for repair, we found that the pin had already been fatigued."

"Look at this curvature. The original straight shaft was forcibly stretched into a banana shape, and it broke due to fatigue damage. We were all shocked when we disassembled it."

"I heard you're doing fatigue research on connectors. I wonder if you could use these physical samples?"

Zhang Diancai's eyebrows twitched, and he finally couldn't help but bend down to look over.

The surface of the pin was covered with scratches, and the shoulders at both ends showed obvious signs of compression and skewing. One side of the middle section even showed signs of peeling.

These metal parts, with even the broken edges showing signs of use, are the best samples for material modeling.

Compared to those so-called samples that "had no load records and were picked up from a waste pile," they were worlds apart.

His heart skipped a beat, and he swallowed back the words "I'm busy".

"Come in and talk."

Zhang Diancai said in a low voice, then turned and opened the door.

Chen Luyang happily carried his tool bag and the heavy pin, and followed him into the house.

As soon as he entered the room, he quickly unzipped the zipper and pulled out an old spark plug that was burnt and deformed, with obvious cracks in the threads.

"Teacher Zhang, this is a faulty part that our repair center just removed. It's a model 212, and it's been in service for three and a half years. It has a high frequency, short range, and frequent cold starts."

Zhang Diancai was taken aback and subconsciously picked up the spark plug to examine it.

The carbon layer is thick, the threaded cracks are clearly visible, and there are fine traces left by thermal expansion and contraction at the end.

"Is this from your repair shop?" he asked, looking up.

"Yes." Chen Luyang nodded.

"Besides the spark plug, I also have a broken pin, but that's too heavy for me to carry to school by myself."

"I've left the remaining samples in the storage room on the first floor of the dormitory building, so it's inconvenient to bring them all over. If you'd like, you can send a student with me to take a look."

Zhang Diancai looked at the spark plug in his hand, feeling as if he were dreaming.

He was met with a rebuff, unable to obtain what he wanted no matter what he tried.
Now, a student, carrying a big stick, blocked the door and offered himself up.

"how much do you have?"

“Quite a lot,” Chen Luyang said.

"As long as the repair shop keeps operating, we can continue to disassemble, record, and categorize parts."
