60s: I have a store

Chapter 414: Living God
Zhou Yimin looked at the time. Tomorrow is Sunday and Zhang Yan is on holiday. They haven't seen each other for a while. Most of the things in the village have been done, so it wouldn't be a big problem if he wasn't there.

Then he said something to his grandfather and grandmother and drove there.

The old man and Grandma Zhou Yimin are 100% in favor of this kind of thing. They can't wait to get married tomorrow and give birth to a grandson the day after tomorrow.

The car body was shiny and gleaming in the sun, attracting the attention of passers-by.

Mounting on his motorcycle, Zhou Yimin sped towards Zhang Yan's university. Along the way, he felt the breeze on his face and felt as excited as if he were meeting his lover.

Zhou Yimin drove his motorcycle into the campus. Along the way, the "thump thump" sound attracted countless eyes.

In this age when bicycles are not popular, motorcycles are undoubtedly a super rare thing.

The students all looked sideways, some were so surprised that their mouths couldn't close, some were full of envy and talked among themselves.

"Look, what kind of car is that? It's running so fast!" a girl asked, not knowing much about cars.

"I heard that this is called a motorcycle. It's very valuable and not available to ordinary people." A young man answered the question.

The students were very curious about Zhou Yimin and wondered where he came from and how he could drive such a precious motorcycle.

Could he be the son of an official? Otherwise, he would not be able to drive such a good motorcycle at such a young age.

Under the gaze of everyone, Zhou Yimin stopped steadily downstairs of the girls' dormitory.

After a while, Zhang Yan and several classmates came out talking and laughing.

Zhang Yan was wearing a plain cloth shirt today, with two pigtails, and a youthful smile on her face. When she saw Zhou Yimin, her eyes suddenly lit up.

"Yimin, you're here!" Zhang Yan walked up to him quickly with her cheeks slightly red.

Zhou Yimin smiled and nodded. Just as he was about to speak, he heard a classmate next to him say, "Zhang Yan, this is your boyfriend. This motorcycle is so cool!"

He immediately asked: "Comrade, are you Zhou Yimin?"

Zhou Yimin nodded: "Yes, I am Zhou Yimin."

When others heard that it was Zhou Yimin, it immediately caused a sensation.

Cheng Lefeng was very excited: "Wow, I didn't expect that I could see the living God!"

Zhang Yan said angrily, "Have you ever seen the God of Death?"

Cheng Lefeng said: "I want to, but there is no such opportunity!"

Zhou Yimin was a little embarrassed: "This is not my first time coming to school, so this should not be the first time we meet!"

After all, we came here to school last time. Since we are in the same group, this should not be the first time we meet. There is no need to be so excited!

Cheng Lefeng explained: "I had something to do at home last time, so I wasn't at school. I didn't see you when you came last time, Master."

Zhou Yimin heard it and realized it was like this: "Nice to meet you!"

Cheng Lefeng said bluntly at this time: "Master, our group has a new topic, can you help?"

When the others heard this, their eyes suddenly lit up. They wanted to say the same thing, but were too shy to speak out.

If this folk god helps, the progress of the project will definitely be ideal, or even completed. Zhang Yan did not hesitate: "Our group is studying a project and encountered some difficulties. We are worried about it. You came at the right time. Why don't you help us?"

And she also thought that such an excellent partner should not be wasted.

Zhou Yimin had no choice but to nod and agree.

Then I followed them to a corner of the campus where there were several tables and chairs, and the tables were piled with books and materials.

There are five people in Zhang Yan's study group, all of whom are students with excellent grades and a thirst for knowledge.

At this moment, they were sitting around the table, frowning as they stared at a notebook full of formulas and data.

Zhou Yimin walked closer and saw that there was a foreign book on mechanical dynamics spread out on the table. It was covered with dense markings. On the notebook next to it were some calculation formulas and data, as well as several sketches of mechanical structures that looked quite complicated.

It turned out that they were studying a difficult problem about improving the factory's new spinning machine. At that time, the domestic textile industry urgently needed to improve production efficiency to meet people's growing living needs.

During the operation of this spinning machine, problems such as yarn breakage and uneven winding always occur, resulting in a high defective rate, which seriously affects the production progress.

Originally, a topic of this difficulty should not be assigned to first-year students. However, due to the excellent completion of the previous project, the instructor wanted to give Zhang Yan and her classmates more responsibilities, so this topic was given.

They cherish this opportunity. If they can complete this project, it will definitely help their future resumes.

When you graduate, you will have more options and your future path will be easier.

And even if it can't be completed, it's not a big problem. In fact, this difficult topic may not be completed even if it is given to a higher age.

Although the team members have solid theoretical knowledge, they lack practical factory operation experience and find it difficult to accurately grasp some subtle changes and stress responses of machinery when it is running at high speed.

Zhang Yan and her colleagues tried various methods, including adjusting the gear ratio, changing the spindle speed, and optimizing the yarn tension, but none of them achieved the desired effect, which gave them a headache for several days.

Seeing everyone at a loss, Zhou Yimin felt a little unsure. After all, although he came from the future, his major was not completely suitable.

But seeing Zhang Yan's expectant eyes, he decided to give it a try. Maybe he could help, just like the last time he helped develop special steel in the factory.

As the saying goes, if you plant a new willow tree, it may not grow into a tree, but if you plant a willow tree accidentally, it may grow into a shade.

Zhou Yimin coughed lightly and broke the silence: "How about we review all the methods we have tried so far and see if we can find some overlooked details."

For example, the same thing happened with special steel last time, so reorganizing it is indeed a good idea.

After all, there are many subtle things that are easily forgotten, but these are often the key.

Everyone nodded and began to talk one after another.

Start from scratch and sort out everything you have studied during this period.

Zhou Yimin listened carefully, writing down key information on paper from time to time. After the lecture, he stared at the mechanical structure sketch, and suddenly an idea flashed through his mind.

"Look, could the yarn breakage and uneven entanglement be related to the resonance generated by the spindle when it rotates at high speed?" Zhou Yimin said, pointing to the spindle part on the sketch.

"I remember some similar mechanical failures where resonance caused uneven force on the components, which in turn caused various problems."

"Can we try to change the material or shape of the spindle to adjust its natural frequency and avoid the resonance range?"
