Let you teach, you play games with the worst class?

until the next shock comes.

Once, twice.

Five times, ten times.

After [-] consecutive impacts, the keel remained unmoved, lying on the impact platform as firmly as an old dog.

The worries on the faces of everyone in Class Nine turned into surprise in an instant.

The administrator's regret also turned into consternation.

He couldn't figure it out, how could it always withstand all the shocks at the last moment when it looked like it was about to fall apart?

Three hundred kilograms!

Even if it acts on human bones, I'm afraid it will only be a sudden death on the spot.

Is such a piece of wood harder than a human bone?

Aside, the floating drone recorded such a scene in its entirety.

Netizens were also shocked and temporarily forgot to breathe.

Did Class Nine really do it?

The spliced ​​keel can really withstand this level of impact.

Teacher Ren didn't say hello anymore? !

The judges still didn't make a sound, they just frowned and thought about the specific cause of this phenomenon.

Only Wang Yu heaved a sigh of relief after seeing the mortise and tenon joints of the keel fitting, twisting and separating.

He knew that what he cared most about had already been resolved.

After fifty shocks, the administrator hit the pause button.

The keel was completely removed.

Subsequent tests are meaningless. Since the other party can withstand [-] impacts without any signs of damage, it will only be the same in the future.

After re-handing the keel to class nine.

The administrator exclaimed:

"You little dolls are really not simple. A piece of wood has really achieved this level."

"I'm going to go out to work as a carpenter in the future. Everyone is a good hand."

"You will never be short of food in the future."

It can be heard that apart from the administrator's admiration, there is also some envy.

Classmate Ah Wei smiled and corrected tirelessly: "Uncle Chang, this is a keel for shipbuilding, not some kind of wood."

"Okay, okay, whatever you say is what you say." The administrator nodded casually, and then asked curiously:

"But I'm surprised, you wooden..."

"keel!"

"How did it become so tough? It looked like it would fall apart in minutes, but in the end it resisted all the shocks."

The administrator is curious about this phenomenon.

The students in Class Nine all looked at Wang Yu.

In terms of explanation, it is obvious that the other party is more professional.

Moreover, the overall design and calculation this time was also led by Wang Yu.

Wang Yu was not pretentious either, holding the keel and began to explain:

"It's mainly because of tenon and tenon joints."

"Teacher Ren said before that mortise and tenon joints are a device that uses force to relieve force."

"We just successfully applied this device to the keel."

"Before, didn't you also have this kind of structure?" The administrator was still puzzled.

"Yes, there were before, and we also considered the problem of force, but they were too tightly connected before. Although they can also have the effect of unloading force, they still have limitations."

"We have also fallen into this vicious circle because of our ignorance of mortise and tenon joints."

"Mortise and tenon, in fact, there is no need to combine them too closely. What we have to do is to exert the maximum effect we need."

"On the keel, what we need most is unloading, and the stability can be appropriately relaxed."

"So, I left some small gaps in each mortise and tenon structure."

"With these gaps, the force received by each tenon and tenon can be easily transmitted to the air, and will not continue to act on the next tenon and tenon."

"In this way, the effect of unloading force can be achieved very well."

"Moreover, because of the existence of these gaps, there is more movable space between the connection points of each mortise and tenon joint, which also provides assistance for stability."

"Although it looks rickety, under the overall construction, they will definitely return to their original positions."

"I only figured this out recently."

"When I was doing mortise and tenon joints before, I left enough gaps because I was not skilled enough, which made the work look abnormally shaken, but it just wouldn't fall over."

"That's why I came into contact with this method."

"No wonder you always left some gaps when you made it before. Feelings are not too trendy in craftsmanship~"

Hearing this, the students in Class Nine were the first to express their emotions.

Although they can understand this more or less, but it is not as detailed as Wang Yu's comprehension.

It's a feeling in their hearts.

As for Wang Yu, it became a principle.

Such a talk also gave the students of Class Nine a sense of enlightenment.

Listening to the emotion of the new classmate, Wang Yu nodded calmly:

"Actually, the main reason is that the craftsmanship is too trendy, otherwise we can do better."

The students in class nine staggered instantly.

Damn, this person is too serious!

At this time, the administrator finally sorted out the joints.

He let out a sigh of relief:

"Students today, it's really not easy..."

Then in the next moment, he asked a question about breaking the defense in a second from Class Nine:

"Since you said that this thing is a keel, it is used for shipbuilding."

"Then how do you solve the pest problem?"

"Once the wood is damp, it is easy to breed pests."

Chapter 271 Class Nine: Tired, destroy it!

"Once the wood is damp, it is easy to breed pests."

As soon as this remark came out, the students in class nine were stunned for a moment.

They stared blankly at the administrator, their eyes were full of blankness, and even their expressions became a little dull.

yes...

How to solve the problem of pests!

Damn, never thought about it at all!

How can there be so many things with a keel? !

Can you still have fun!

Immediately, their expressions became tangled, and many students looked at the administrator.

There was a hint of confusion, a hint of pleading, and a hint of anger in his eyes.

You said you are fine, why remind us? !

Shall we get excited for a while? !

But the administrator didn't pay much attention to it. He just saw the plea and knew what the students in front of him meant.

This is to hit the idea on himself!

He spread his hands helplessly:

"As you know, I'm just an auto parts maker."

"It's not easy to find the problem."

"I'm afraid it's a little difficult for me to solve it."

"In the words of your young men."

"It's just that you may have misunderstood Uncle Chang and me..."

The students in class nine watched him silently, and it took a long time before he sighed, and the tone became sad:

"Then you don't need to speak out so bluntly, it makes us very distressed."

"In such an old society, has no one told you that it is better not to ask a question than to ask a question without a solution?"

"It's easy to get fired if you go to work like this..."

"That's why I came here to make auto parts myself~"

The administrator answered naturally.

The students in class nine were startled for a moment.

Damn, why are these adults so impeccable in some aspects?

Is this an adult who has been beaten by society?

360-degree all-round without dead ends? !

After everyone struggled for a while, seeing that the administrator really had no choice but to drag the ashes of the completely completed dragon back to his warehouse.

The originally excited mood was completely extinguished.

Everyone looked extremely tired.

Blowing my liver for several days, the result is only to solve a small problem on a widget?

Shipbuilding is too difficult!

For a while, many people even had the slightest thought of giving up.

I grew up so big, when did I suffer from this crime!

But after thinking about the experience of the past few days, they felt that it was a loss to give up suddenly.

If you really just give up like this, wouldn't it mean that you have been blind for a few days?

At that time, if the cheap teachers at home are not in order, they will have to laugh at themselves.

【Hey, look, I wasted more than half a month for nothing~】

【The result is nothing~】

[Spicy chicken! 】

Thinking of this possibility, and looking at Ren Yan who was still lying dead on the chair, they immediately put this thought out of their minds.

Isn't it just a matter of deworming?

Done!

It's all over now, whoever gives up is a dog!

At this time, they do not know that there is a word called the cost of silence.
