My art is too advanced.

Chapter 49: You already know how to add one plus one, let’s practice calculus! (Please give me a monthly ticket!!!)
"Let me first talk about the internal force analysis of statically determinate structures." Zhou Yue said.

Afterwards, draw a schematic diagram of the beam.

Followed by.

Zhou Yue put down the monograph in his hand. He had no intention of giving a lecture according to the book.

Start analyzing the schematic diagram.

List the differential relationships and start talking about it.

The students below showed surprise expressions.

This is the content of structural mechanics.

Not beyond the scope?

And it’s considered basic?
After analyzing the forces, several experts in front of them nodded slightly. If nothing else, this typhoon is pretty good.

But it's useless!
"Okay, have we learned the internal forces of these simply supported beams?"

"I've learned it." Some students began to answer.

Zhou Yue looked over and found that he knew this classmate.

His name is Ding Qi, he is a junior student and used to be his subordinate in the student union.

"It's good that you have learned it. Now let's take a look at multi-span statically determinate beams." Zhou Yue said.

Zhou Yue also listed several internal forces of the beam.

Then analyze them one by one.

This time, it took a very long time. Multi-span beams obviously take more time and are more complicated than single-span beams.

The force is not single.

The blackboard was already firmly occupied by the formulas he listed.

"Do you understand?" Zhou Yue looked at the analysis on the blackboard and asked his classmates.

"can."

"If you can understand it, this is also simple. We have learned structural mechanics before."

"Yes, the senior explained it very clearly. It was like learning it all over again."

“These are very basic.”

"."

Zhou Yue wiped the blackboard and said, "I'm glad you understand. Now let's look at the complex nodes of this beam."

soon.

A crooked and complex node appeared on the blackboard.

Everyone was dumbfounded.

What is this?

A tangle of wires?
All the previous analyses were straight beams!

This beam consists of many spans connected together, it's a mess and irregular, with several edges cantilevered out.

Most importantly, irregular!

Even this beam has a curvature?
What is surprising is that there are only a few simple supports below.

Logically speaking, with so many irregular beams, is it true that this house will not collapse?

All students, "."

Three academicians, "."

Teacher Guo, "."

They feel like they have been fooled, as if they were asking you, have you learned that one plus one equals two?
They replied that they had learned it.

But, he suddenly asked a calculus problem?

"Let me ask a classmate to come to the blackboard for analysis." Zhou Yue said with a smile.

The students below lowered their heads one after another.

What a joke.

They don't want to die, right?

This question was obviously beyond the syllabus. Even if they could analyze it a little, they would be daunted by such a complex structure.

And the structure is a whole.

It is not only necessary to analyze the internal forces locally, but also to consider the whole.

That is to say, the force in some places may be partially offset by the force in other places, and you have to peel it out bit by bit.

Moreover, it is such a complex and large node that it really makes people's scalp tingle!

"Ding Qi, come on, didn't you just say you learned it?"

"what?"

"me?"

Ding Qi looked helpless, but he gritted his teeth and walked up.

"Brother Yue, you are going to kill me." Ding Qi said helplessly.

The students below all laughed.

Although they themselves don't want to go up and do it, they still like to watch the fun when someone else goes up.

"I'll do the analysis and you can help me write the formula."

Zhou Yue naturally would not embarrass him.

His hands were just tired, so he asked someone to help him write.

"Let's start from the end point of this beam and analyze it section by section."

"..."

Zhou Yue talked about this complicated node for a full hour.

During this time, he saw many classmates drowsy.

He doesn't blame them.

That’s right, this is structural mechanics!

Even this complex node is more structural mechanics than structural mechanics!

Analyze it bit by bit, peel off the cocoon and analyze all the forces inside.

But it is true that this complex node still does not deviate from what he said before, it just adds some irregular structural forces.

Have a foundation in basic mechanics and mathematics.

Looking at this node, one can only say that it is very complicated, but it is far from being incomprehensible.

Tan Xue was also watching from below.

And his eyes became brighter and brighter.

Nodding from time to time.

He had once reviewed the electronic version of this textbook for Teacher Guo, but now looking at the textbook in his hand and the explanation on the blackboard, Tan Xue felt.

Zhou Yue really understood structural mechanics thoroughly, and his calmness showed that he was definitely able to control everything.

"He is a talented designer and also a genius in structure. No wonder Mr. Guo values ​​him so much."

Tan Xue glanced at the verification paper in her hand, which was also densely covered with formulas and analyses.

The final conclusion is no different from the one calculated on the blackboard.

That's what structural mechanics is all about.

For someone like Tan Xue who is interested in structural mechanics, after analyzing the internal force, he even felt a sense of satisfaction.

In contrast, those with less interest will feel drowsy.

For this thing, if you don’t like it, you don’t like it. If you can’t do it, you can’t do it. There’s nothing to say.

An hour later, Ding Qi filled a whole blackboard with writing before leaving.

In some places, Zhou Yue just briefly skimmed over them, but he was also able to add in the formulas. It must be said that there are no mediocre people in Ning University.

You can’t pass the exam if you don’t have enough brains.

Zhou Yue made a simple conclusion and bowed slightly towards the crowd below.

There was immediate applause from below.

Teacher Guo turned his head and quietly asked the principal for his opinion.

"What do you think?"

"I have no objection. You can make the decision in your department. If you need my signature, you can come to me directly."

After the female principal finished speaking, she sorted out her folders, nodded to Zhou Yue, and walked out.

After all, it was their own department's business, so she wouldn't get involved.

"What do you three teachers think?" Teacher Guo also looked at the three old professors.

"I think it's very good. He goes from the basics to the complex and goes deep into the details. From this complex node, we can see that he has sufficient knowledge of structural mechanics." The silver-haired female professor nodded.

"I think so too. Having clear logic and being able to explain complex issues clearly is a skill. I am fully qualified for a teaching position."

Teacher Guo finally looked at the old dean.

The old dean still has one last vote.

And this vote is crucial.

Teacher Guo also knows that for universities, especially for lecturers, how the class is taught is not that important.

Academics are the more important part.

But Zhou Yue already has an academic monograph, and his influence has begun to show.

Not bad at all!
"Just make your own decision. I support you." Old Chen still smiled.
