Peng Changxu continued to sneer, "Yes!"

Zhuo Lang slapped the table, "Every section, he is subject to two pulling forces from the two ends next to him, it's that simple!"

Jiang Xudong was angry and gave him a big showdown, "What the hell? Tell me clearly what is going on!"

Zhuo Lang is a little aggrieved. He knows that the two brothers are kind-hearted in helping him overcome difficulties, but can you guys be gentler?

"Hey! Keep your voice down, this is not my class!"

The teacher patrolling the building was none other than Chinese teacher Li Xiaobo. He was standing at the door and knocked helplessly.

The three of them shrank their heads in embarrassment.

Li Xiaobo looked at them all with red faces and felt a little inexplicable sadness in his heart.

However, this should be regarded as the most beautiful appearance of students in their youth.

After the summer vacation, there is another group of cubs.

And they...

One look is all it takes.

He sighed, "If you have any questions, just go to the conference room and ask your teacher Wang."

Zhuo Lang shrugged his shoulders and said, "I'm going. There are so many people around Teacher Wang that I can't squeeze in."

Jiang Xudong said helplessly, "This is a question that he doesn't know enough about. He won't be able to solve it in a few minutes."

"If you don't work hard at ordinary times, you just have to improvise." Peng Changxu also had a look on his face, hating that iron cannot become steel.

Li Xiaobo spoke doubtfully, "You are stupid, just ask Qing Yun.

You, Teacher Wang, all said in the office that Qing Yun’s teaching level is still above him."

The three brothers looked at each other and quickly dialed Qing Yun's cell phone.

After a while, Qing Yun came to their room.

After looking at their situation, I found that although the standard room is not small, it is definitely enough for one person.

But if a few people gather together while studying, that would be a bit nonsense.

However, he didn't say anything about letting a few Hulu babies go to the 'Presidential Suite'. This needs to be discussed with Qin Manman in person.

"Young man, tell him what's going on." Peng Changxu said angrily.

Qing Yun took the question and looked at Zhuo Lang's draft paper, and roughly understood it.

"This is not a question, it's because your physical and mechanical analysis system has not been sorted out well.

Come on, I asked you to write, and I remembered these sentences: 'There must be gravity, elasticity can be seen in all directions, friction can distinguish movement from static, and the direction must be judged accurately'."

After seeing Zhuo Lang write it down neatly, Qing Yun sat on the bed and started talking,

"To analyze the force on an object, we must first select the object of study and isolate it.

According to the needs of solving problems, the research object can be a particle, a node, a single object or a system composed of multiple objects..."

"Analysis in order, just follow the order of my formula.

But you should note that elasticity and friction are both contact forces.

You need to circle around the research object to see how many basic points or faces there are between the research object and other objects.

Each contact surface may have two contact forces for the object you are studying, and you need to analyze them one by one according to the elastic force and friction force..."

Qing Yun spoke slowly, Zhuo Lang's problem was actually very simple, that is, there was confusion between the overall method and the isolation method during the force analysis.

This is a commonly used method in mechanical analysis, and each has its own advantages.

It can also be applied comprehensively, by isolating first and then whole, or whole first and then isolating parts.

However, if you analyze it halfway, it will be funny if they are mixed together.

Zhuo Lang suddenly realized it, and his thinking suddenly became clear, "Oh, for this question, you have to focus on the top first, and then look at the bottom."

He quickly began to unravel it.

Qing Yun smiled, turned to Peng Changxu and Jiang Xudong and asked, "Second brother, third brother, what are you unclear about? Do you want me to sort it out for you?"

Peng Changxu hesitated for a moment, "I won't delay your review, right?"

Li Fangping and the school leaders specially said hello, asking everyone not to disturb Qing Yun's preparation for the exam.

Qingyun's incredible results in the third diagnosis gave them an idea of ​​this year's top pick.

In the 4,793 super high schools, the number one pick effect is so obvious. The number one pick that year basically directly determines the number one pick and the 985 rate three years later.

Ninth Middle School lost the battle for the No. 1 pick and gradually began to decline.

The current battle for the top spot is only between the Fourth Middle School and the Seventh Middle School, and the Ninth Middle School can only take advantage of it once.

Qing Yun and his group entered the school in 2000, so they were originally the junior year of No. 4 Middle School.

However, with him as a super coach who is not a coach, the competition of No. 4 Middle School was extremely popular, and many places were taken from No. 7 Middle School.

If he can win the college entrance examination again, then in this three-year cycle, the fourth middle school will be able to win.

Coupled with the class that accidentally snatched away from the No. 7 Middle School in 2001, the No. 4 Middle School is enough to widen the gap in the next 3-5 years and establish the dominance of the No. 1 High School in Xishu.

Qing Yun also knew what was going on.

He was also laughing in his heart, this was a completely different trend from his previous life.

In the previous life, No. 4 Middle School was bullied miserably by No. 7 Middle School this year.

After all, Qin Manman and others did not take the exam.

And the next year, No. 4 Middle School, which was supposed to celebrate the Chinese New Year, was overthrown by the cooperation of No. 9 Middle School and Mian Middle School from other places.

Mianzhong directly offered a capitation fee of 300,000 yuan per student to recruit the top students from No. 4 Middle School to take the college entrance examination in Mianzhong.

If you pass the exam in Qingbei, you will receive a million-dollar prize.

Therefore, with the power of capital, Mianzhong created a myth and kicked off a period of private school craze.

However, these things have nothing to do with him.

He came to this time and space not to save anyone.

Not that holy mother, I just simply don’t want to see my alma mater being bullied.

Spend money, right? Let's see who has more money then.

As a public school, Jincheng No. 4 Middle School didn't expect such a move at the time.

"What a waste of time, hurry up, don't waste your time."

Without any nonsense, Qing Yun started lecturing directly in their dormitory. For him, lecturing was also a review.

As for the two subjects of Chinese and Biology, he was sure that he had reached the limit. If he could go up one more point, he would not be able to do it in a few days.

After learning the news, Li Fangping rushed over to take a look. Faced with Qing Yun's explanation, he could only shake his head and left helplessly.

Learning God cannot be persuaded by a teacher.

After teaching for so many years, he knows very well that top students have many talents, or hard work.

But it’s hard to learn the magic.

Not all top academics can be called academic gods.

Even in a school that can produce dozens of Qingbei students a year, how does it count to be admitted to Qingbei?

If this is the case, then the term "Xue Shen" is too worthless, right?

Qingbei, who came out of answering questions, is a top question maker.

Your true colors will be revealed once you enter university. How can you be worthy of being called a top student or a god of study?

Do you really think that the 7% dropout rate in Qingbei every year is not something that can be arranged?

It's just bad luck, those who are question writers and those who think that everything will be fine after passing the exam, in fact, life in 985 University is worse than death.

For example, the University of Science and Technology of China and Fudan University have dropout rates of 12%.

Scholars, in addition to hard work and talent, also have a heart that is absolutely confident in themselves.

In super high schools, including No. 479, it is difficult to produce a top student within three years.

The last scholar in Jincheng was named Zhang Wei, who was born in Jincheng No. 7 Middle School.

Now in the Mathematics Madhouse at Yanda, we are competing for hegemony with three other outstanding figures: Xu Chenyang, Yun Zhiwei, and Zhu Xinwen.

And Qing Yun, at the end of her senior year in high school, showed this temperament.

It's a pity that I have to become a merchant.

After Qin Manman learned the news, he shook his head helplessly.

Forget it, just take care of yourself.

He closed the book and summoned a few good Jimeis, "If you have any questions, just ask me directly. Don't waste time waiting in line."
