The next day, after breakfast meeting, the students of Class 9 set off in front of Ren Yan, in front of Ren Yan, in a vast army of 11 directions and headed towards the warehouse.

There was still no notification to Ren Yan.

Before leaving, he even glanced at Ren Yan provocatively.

It immediately made Ren Yan convinced that these boys were retaliating!

Why do you just hold grudges like this?

Didn’t you just take a taxi in front of you?

As for?!

So Ren Yan had to take a taxi again, whistled past in front of the neat steps of Class 9, and waved to Class 9 at Class 9, and was already fighting back.

After the two sides arrived at the farm and compared each other with a middle finger, the students in Class 9 went into work.

If you don’t be able to beat you, let’s make arrangements for you!

This thought flashed through the minds of the students in Class 9.

Fortunately, after really working, the feeling of being crushed was much less.

Distraction is really effective in changing moods.

Since nine keel parts were forged yesterday, today Class 9 put all the focus on the mortise and tenon structure.

Although the length of the nine components is still much different from a complete keel, Class 9 still feels that mortise and tenon are more important now.

They are already very skilled in shaping keels, but people know what other problems will arise above the mortise and tenon.

If they fail to complete it once, they will always feel at ease.

This feeling has been produced subtly over the past few days.

The students in Class 9 didn’t know whether this behavior was right or wrong, but they were not disgusted at all.

Having an accurate psychological expectation in advance is always much more reliable than believing in yourself.

They have encountered such things very often.

Sure enough, after the official start of construction, Class 9 soon encountered problems.

The first is the connection between each mortise and tenon.

Because the structure of the keel is completely different from what they have done before, it is completely impossible to lock the keel that they have always used before.

It will fall off at any time.

Secondly, the stress points of each mortise and tenon are also completely different.

After the first time, the splicing was barely completed.

Class 9 tested the keel according to his usual habits.

When the structure is barely stable, a little vibration will indeed not cause any damage to the keel.

But once this vibration escalates, the connection between the keel will immediately crack, causing the scene they had simulated in their minds to shatter.

The connection point not only did not become the force-release point, but instead became the biggest weakness of the entire keel.

This is the case with the keel made of nine parts, but it really reaches 150 meters, and what about the keel made of more than forty parts?

They simply dare not imagine.

So at the moment of failure, they immediately started an analysis.

And questioned the pattern of mutual struggle and unloading force.

It is obvious that they are connected completely according to mortise and tenon, but in the end they are not ruined.

Although it sounds reasonable, it turns out that this thing doesn't work.

However, after many brainstorms, they still gave up this doubt.

It was Wang Yu who convinced them.

The process of persuasion is still simple and hard-core.

Wang Yu simply calculated a few formulas and shattered their doubts from practical reasons.

For the current Class 9, they can fully understand some simple mechanical formulas.

Then, they found the root cause in Wang Yu's formula.

Force analysis error.

Narrow considerations.

They did not consider the force point generated by each mortise and tenon, as well as the maximum force that can be withstood.

They just took the most direct situation into consideration.

Some chain reactions that may have caused by mortise and tenon are not considered at all.

So, inevitably, Class 9 fell into the transformation of work again.

According to the questions raised in front of me, I plunged into the ocean of calculation.

Even Wang Yu was not spared.

Although he is indeed a top student, he has learned any knowledge points very well.

But in practice, there are still shortcomings.

No matter how you simulate in your mind and pay attention to it in life, it still seems insufficient when you encounter problems.

This was the case when the wind direction was calculated last time, and this time the keel was still built.

Even this time is more troublesome than last time.

Because he needs to consider more details this time, his understanding of mortise and tenon structure is too shallow.

Fortunately, he now has many more people from his peers than before.

Although their abilities may be limited.

But under the same goal, Wang Yu still exuded a passion that he had never had before.

Is this the feeling of being a fellow?

Also is a comrade often mentioned by the older generation?

At this moment, he had a deeper understanding of the word.

In this kind of tension and stimulation is full of various uncertainties and can receive feedback at any time.

Time quietly passed.

Three days have passed in a flash.

During these three days, Class 9's progress was quite gratifying.

Although they still haven't officially handled the keel, they can clearly feel that they are getting closer and closer to success.

It is a kind of fantasy feeling that cannot be named or identified, but it is a clear feeling that comes to everyone's heart.

From the crazy mapping calculations on the first day, to the trial testing and re-analysis on the second day, to the increase in the number of testing on the third day, the number of modifications has decreased.

All of them can experience their own progress at all times.

This feeling even makes them slightly addicted.

During this period, they not only found the best way to fit the keel, but also made their own small modifications on the mortise and tenon through continuous practice.

Each mortise and tenon interface is not as clear as before, but is more rounded.

After the emergence of this kind of mortise and tenon, the keel's force capacity has indeed increased significantly.

The impact that can withstand has also risen by several dimensions.

Although they lost many perfect parts during this period, they were not discouraged.

Even though Awei felt extremely sorry for the class pay, he also understood that this was a necessary loss.

Otherwise, why did he and Wang Bo think of buying more wealthy wood before?

Moreover, during these three days, not all of them were concentrating on calculations.

Some students who are really calculating have taken the initiative to fumigate wood.

They made a steady stream of practical materials.

He acted as a perfect logistics staff.

Everyone did their best, and the unprecedented sense of unity made all netizens feel shocked.

Although they had known before that Class 9 is very united now.

But I never expected that they would unite to this extent.

With just a few running-in times, everyone can quickly find the job that suits them in a new job.
