Rebirth 1990: I have three golden fingers

At almost eight o'clock in the morning, Fang Bai walked into the classroom and heard the boys discussing the Eight Mechanical Monsters. After asking, he found out that his roommate had posted a couplet.

Fang Bai sat for a while, then the bell rang and class started.

After two days of class, Fang Bai conceived the structure of the floor pump while listening to the class.

While running in the morning, I suddenly found that the design idea was clear, and I started designing a floor pump.

The first step is to design the concrete conveying speed, which is directly related to the choice of diesel engine power.

Faster conveying speed means the greater the power of the diesel engine, the higher the cost and the higher the selling price.

The conveying speed is too slow and the cost is not much lower. No matter how cheap a low-power floor pump is, it still costs more than 100,000 yuan. Small companies these days are still reluctant to buy it.

Therefore, after careful consideration, Fang Bai decided to design the delivery speed of the first floor pump to be 30 cubic meters per hour, and the stone size should not be larger than 30 mm.

If you want to transport 30 cubic meters of concrete to a height of 50 meters, it is equivalent to doing work.

Each cubic meter of concrete is about 2.2 tons, about 22,000 newtons = 2.2WN;

30 square meters is 660,000 N cattle.

Work W=Fs=FH=660,000X50 meters=33 million joules.

If the theoretical design vertical height is to be transported to 150 meters, that is, when the height of more than 30 stories is high, the work will be greater, reaching 99 million joules.

And power: P=W/t time=9900W/3600 seconds=2.75W watts=27.5 kilowatts.

In fact, during the transportation process, friction occurs between the concrete and the pipe wall, and there is friction loss in work.

Therefore, Fangbai calculated that the diesel engine power needs 45 kilowatts to be reasonable.

The second step, which is the diesel engine power, is also directly deduced;

The third step is to calculate the working pressure based on the pipe diameter.

The diameter of the delivery pipe cannot be too small, otherwise concrete will easily block the pipe;

Of course it can’t be too big, too big means less pressure.

Fangbai initially selected a pipeline with an inner diameter of 125 mm and calculated the delivery pressure to be approximately 15MPA.

This pressure is very high, 15MPA is 150 standard atmospheres!

High-pressure alloy seamless pipes must be used, and seamless pipes with an inner diameter of 125 mm happen to be standard pipes, so there is no need to customize them.

Calculate the pipe wall thickness and material strength to check whether it is large enough for this pressure situation.

At the same time, considering that the concrete transportation will wear the pipe wall, enough wear allowance must be left. Otherwise, if it is used for a long time, the pipe wall will become thinner and the pipe will explode, which will kill people. What will be ejected will not only be water, but also high-speed stones.

The design calculation workload is not small and many factors need to be considered.

The same change will directly affect other conditions.

Designing products is not about pursuing perfection, but about being reasonable and taking into account cost factors.

Otherwise, the manufacturing cost will be high, the selling price will be higher, and it will be difficult to sell.

Fang Bai spent a whole morning and finally finalized the design factors of the first floor pump.

The main structure of the ground pump is composed of a hopper, a pump body, a hydraulic cylinder that drives the slide valve, a slide valve, a delivery cylinder, a main hydraulic cylinder and a pilot valve.

After determining the main design factors, the next step is to design the main hydraulic cylinder and delivery cylinder according to the diesel engine, and then design other structures.

During class, Yang Tan sat next to Fang Bai. He saw that Fang Bai had not listened carefully to the class all day, but was scribbling on a piece of white paper. He started drawing in the afternoon. At first he thought it was painting, but in the end it seemed Draw mechanical diagrams.

When get out of class was over, Yang Tancai curiously asked Fang Bai:

"Monitor, what are you drawing?"

"Design a hydraulic cylinder." Fang Bai replied casually, without raising his head, and continued drawing.

"We have just received mechanical engineering books, and you have already designed and drawn pictures before class?" Yang Tan was shocked. They started the same way. They had just been born and were just learning to talk, but they had already learned to run.

No, this is about to fly.

"I've finished reading and studying during the summer vacation."

"Pervert, you are so offensive!"

After a while, many students knew that the monitor had already started drawing and designing.

Although I am not optimistic that the things designed by the monitor will be usable, at least I can already draw pictures and design them, and my learning speed is many times faster than that of all my classmates.

Fang Bai spent the next two days drawing pictures.

There were times when he was tired from drawing. After school, he asked several class committee members to stay and discuss part-time jobs.

Li Kai, secretary of the Communist Youth League, was the first to ask: "Squad leader, are you really doing a part-time job?"

"Do you think I'm joking?" Fang Bai asked with a smile, "Everyone is short of money, and many students have problems eating meat. Now that I am the class president, I still have some business skills, so I can provide some welfare for the class.

But I only come up with plans and money, and your class committee will divide the rest of the tasks, and then your classmates will do it. We make money together and share the money together. Any money lost is mine.

Of course, the premise is that it cannot affect learning, otherwise it will be picking up sesame seeds and throwing away watermelons. It can be regarded as social practice in advance.

Please help collect students who are willing to participate. If you don't participate, you will definitely not get any money. "

"Okay, monitor, please make arrangements. I want to participate too."

"I'm also participating, but I don't know what you want to do, monitor."

None of the four class committee members had any objections. Since the class leader paid for it, everyone should contribute.

The monitor said that there is no problem. There are many poor students, and many students have difficulty eating a meal.

Fang Bai nodded. He had thought of several ways to make money in the past few days and analyzed and compared them.

First, to open a student supermarket, students are responsible for the management, taking turns to be on duty when there are no classes, and hiring people during main business hours. After deducting various costs and interest, the remaining profits are distributed according to merit.

An investment of 100,000 yuan is enough to open a 300-square-meter student supermarket, but it is difficult to find a large store.

The supply chain required to open a supermarket is the same as that of multiple supermarkets. Xinghai Company has been preparing to open a supermarket for several months and has found supply chains for many products. Now it is just a matter of picking out the best-selling items.

Currently, the profit of opening a student supermarket is very high, and it will not be a problem until thirty years later. There is a lot of potential.

Second, set up training classes for middle schools. There are no training classes now, but there are quite a few tutors. But many parents cannot afford one-on-one tutoring, or cannot find a satisfactory training institution.

Compared with training institutions, Fang Bai feels that it is not as fast as opening a supermarket to make money.

He still has many ways to make money, but he should not play too much. The same thing is enough. Moreover, Xinghai Company has made a lot of preparations. All it needs to do is keep the supply chain issues confidential.

"I decided to invest 300,000 yuan to open three open student supermarkets, respectively at Jiaotong University, Textile University, and Medical University. What you need to do now is to organize students to investigate the stores to investigate what sells well and whether the stores can be sold or rented. , how much is the rent?”

Before Fang Bai finished speaking, the four class committee members were already dumbfounded: "Class, monitor, did you really invest 300,000 yuan?"

"Not 30,000 yuan? 30 households worth 10,000 yuan?"

"Oh my god, monitor, you have so much money!"

Zhang Li's eyes were the biggest and roundest. She couldn't imagine how much assets his family must have if the squad leader is so rich.

Fang Bai said calmly: "This is what I managed to save by starting my own business. The average family is 100,000 yuan, and the area is about 300 square meters. It should be enough. First try to find a store in the school. The key is location.

Of course, it is difficult to find a store in the school, so it should be located outside the school where there is a lot of traffic. "

After finishing speaking, the expressions of the four people were still in shock.

Fang Bai patted the table, and everyone came back to their senses.

Li Kai said excitedly: "Squad leader, I am listening carefully, but I am too shocked."

Zhang Li also had a look of surprise on her face, but she was a little worried and said: "Yes, the investment is so big, what if we lose money? Don't we need to conduct research?"

Fang Bai understood the reaction of these students. Three hundred thousand yuan was too much in this era. If evenly divided into the hands of each student, it would be enough to spend four years, and it was more than enough.

But he doesn't plan to do this. Donating money directly is meaningless and will harm others.

It is quite interesting to ask his classmates to help him make money. It helps others and also helps himself.

It doesn't matter whether he makes a lot of money or not. As long as he can instruct so many classmates to fool around with him, he can be happy. People can't just make money in life.

“No research required, just get started.

I have already done the research work, so just follow my arrangements and don't make your own decisions.

The loss is mine, but you must follow my arrangements. "Fang Bai said seriously, three hundred thousand yuan is not a lot for him.

However, what he hates most when investing is someone messing around.

There are now 60 people in the class. If everything needs to be discussed, there will definitely be different opinions. This is definitely not possible. He does not engage in voting, and he directly speaks out.

Fang Bai continued: "If a profit is made, each class committee member will receive a 0.8% dividend, and each of the other participating students will receive a 0.6% dividend. The hourly salary will be calculated based on the hourly salary. Currently, the hourly salary is 1 yuan, which will temporarily subsidize some urgently needed money. classmates.

You need to list the tasks and rewards. Students will come to you to pick up the tasks, and they will only get paid after completing them.

Let me remind you that within four years of college, you will only have dividends, but not equity.

If you do something that harms the team, your dividend for the year will be cancelled;

If a class fails, the bonus will be deducted, 0.1% for each course;

If you make special contributions and achieve outstanding results, you will be rewarded separately.

If done well, it won't be a problem for each person to earn several thousand yuan a year.

If the standard is not met, it means that everyone has not done a good job, and naturally there will be no dividends.

After graduating from college, if development goes well, I will allocate equity according to everyone's contribution in the past four years. Do you understand? "

Fang Bai didn't have time to participate in this supermarket, so he just acted as the shopkeeper. He mainly relied on his classmates to manage it, so it was normal to pay dividends.

If it is done well and it becomes a chain store, Fang Bai will naturally benefit.

If no dividends are given, these students will only receive dead wages and will not actively open any chain stores. After all, opening up new territories has nothing to do with them. Why are they so tired and less motivated to work? In fact, Fang Bai earns less.

It seems like you are at a disadvantage, but in fact you will gain something if you give up.

Giving more bonuses will not solve the problem of belonging. Only when you feel that you are working for yourself will you work hard.

Moreover, 300,000 yuan is not much to him at all. It is unnecessary to worry about the grudges and grudges when giving someone a piece of candy. He can just have fun and not care whether his classmates are grateful to him.

If Fang Bai spends a lot of time doing it, then he must make a big investment, and it is impossible to pay dividends to his classmates. He can just pay his classmates normal working wages.

Different situations, different treatments.

"I guess I understand. I don't have any objections. As long as the squad leader points me, I will go there, hehe." Zhang Li was the first to express her opinion. If she can get several thousand yuan a year, it will definitely be enough, and there are many more. With the savings, you can do a lot of things.

Li Kai, secretary of the Communist Youth League, beamed: "Haha, I definitely support it strongly. The squad leader is seeking benefits for the whole class, and every student is a small shareholder."

"I understand, monitor, are we starting a business?"

"That's right. You should contact the school and see if you can apply for a store within the school."

Fang Bai reminded, "I have other investments outside of school, mainly relying on the whole class. But if you have problems that cannot be solved, you can come to me. But don't come to me for general matters. If you come to me to solve any problem, then I will simply come to you." Not voting anymore.

This is also an opportunity for everyone to practice. There are so many students in the class, so tasks should be assigned to those who are good at them.

In the final assessment, I voted down. "

After finishing speaking, he took out a wad of money from his backpack, took out twenty hundred-yuan bills and slapped it on the table: "This is the funds for the early activities, I will give them to you after you use them up.

Zhang Li and Li Kai are jointly responsible, and their wages are also deducted from them. The four of you discuss it and then inform the classmates.

After I find a store, I will ask someone to register for a business license. "

After Fang Bai finished speaking, everyone asked some questions, such as what is an open student supermarket, what is the appropriate profit point, etc.

Fang Bai explained everything one by one. After watching and chatting for a while, he ended the class committee meeting and returned to the rental house with his backpack.

During dinner in the evening, Fang Bai asked Li Xiaolong and Wang Dakai how the house decoration was progressing.

Fang Bai usually attends classes and does not need to follow Wang Dakai and Li Xiaolong for the time being, so he arranges for them to supervise the decoration and at the same time get familiar with the surrounding area.

After a few days, after Fang Bai finished designing the floor pump, he arranged for them to purchase spare parts for the floor pump and entrust processing.

The issue of dividends and shares is quite controversial. I think many readers are not clear about it, thinking that giving dividends means giving shares. This should be clearly distinguished. Giving dividends is actually the same as getting high commissions. Give more when things are done well. The explanation is very clear in the article.

Why do some readers think that giving dividends is like giving assets to classmates.

Dividends are not equal to shares. The company has profits, and they are after-tax profits, so students can get more money, which is the same as high rewards.

Giving shares means giving assets, which is equivalent to giving money for free. It’s different. Don’t get confused.

To put it another way, if there is a start-up company, the salary is only a little higher than your current company, and the scale is also smaller. I guess you are not willing to go. Even if you go, after work, the company will have nothing to do with you, and you will not work hard. , and even catch fish.

But when it comes to dividends and even opportunities to get shares if you do well, if the boss doesn't keep an eye on you, you will take the initiative to find something to do.

If you don't work hard, other colleagues who get bonuses will criticize you when they see it.

Besides, three hundred thousand yuan is just the protagonist’s spontaneity, one percent of his assets.

If you have 100 million yuan, you can spend hundreds of thousands of yuan as a reward, or donate it, or buy a big toy, as long as you are happy.

Then why can't you accept a group of top talents to help you open a company and get dividends? And it also helps you make money.

In fact, the feeling of disapproval that Xinghai Machinery Company may give to classmates and friends is completely unheard of. This is an illusion caused by reading other books.
