Chapter 271 Have you ever considered ‘pest’?

"It's done, it's done!"

"This is the keel that brings together all our hard work!!"

In the warehouse, a keel team surrounded by students in Class 9 sent a refreshing roar.

In the middle, Xu Kai held a dragon bone high with both hands, looking up at the sky as if he was doing some kind of ceremony.

On the side, Li Cheng and Wang Bo and others were inevitably excited.

This keel is the longest working hours, most thoughtful and the most complex mortise and tenon structure they have made in the past few days.

It can be said that it has gathered all their efforts over the past few days.

Whether it is the analysis of stress, the calculation of impact, and the consideration of various details, they have reached the limit they can reach at present.

If this time fails, they really don't know what to do.

Eighty times I have to ask myself the cheap teacher.

But these days I have been competing with the other party in "Qi Xixi".

If you ask now, would it be a bit embarrassing?

Doesn’t this mean we have voluntarily given up?

The students in Class 9 shook their heads slightly in their hearts.

In this regard, they really don't want to give in easily.

We must hit Teacher Ren’s arrogance.

Otherwise, the other party will become less and less accustomed to being a human being in the future!

"No matter what, let's check the actual impact now."

Wang Yu in the crowd pushed his glasses, and the pen in his hand almost slid onto his face.

"Yes, test and test!"

Only then did everyone in Class 9 come to their senses and walk outside the warehouse with keels clustered with keels.

Ren Yan has become accustomed to this.

Because there is no device in the warehouse that can satisfy their actual stress, they will go outside to find help every time they test it.

Although it's not clear what they are using to test.

But Ren Yan was not panicked at all and had no intention of moving his position.

Anyway, you will know the result after a while.

Based on his understanding of the students, these guys cannot hide things.

Anything that happens is always revealed at the first time.

If it fails, it must be the depressed look he used to be.

If you succeed, you will be happy if you don’t come back.

So as the students got farther and farther away, Ren Yan was unmoved at all and even yawned.

In a port area, in a certain automobile parts warehouse.

The administrator looked at the group of students in front of him, and his eyelids shook:

"You guys are here to test your wood again?"

"This is the ninth time in these three days."

"Even if I help you for free, you guys can't get so fucked."

"If this continues, I will charge a fee~"

The manager put down his life in his hand with a little pain and looked at the "wood" in Xu Kai's hand.

Upon hearing this, the students in Class 9 laughed apologetically.

"Uncle Chang, how can we say it is wood? We are keels~ keels for shipbuilding~"

"For safety reasons, you must not test it~"

"And you don't have much to do on weekdays. It's just something you can do if you can help us get an impact."

"You just have the heart to reject such a group of young people as we have ideals?"

The administrator gave them a blank look:

"I don't know if there is any ideal, you are quite annoying."

"We agreed in advance. At most, we will get twice a day in the future. If you don't have too much, you Uncle Chang will not be able to bear it."

The students in Class 9 nodded quickly, and then took the keel in Xu Kai's hand and walked towards the corner of the warehouse.

There is a device that specializes in shock testing, although it is mainly used to test certain accessories of cars.

But because it can regulate the strength, the upper keel can barely achieve the effect.

This place was finally found by Class 9, and all the tests were completed here.

Soon, the keel was placed on top of the equipment and the management started the equipment.

The velocity setting is the same as last time, starting from 100 kilograms.

The impact begins immediately.

A solid iron pillar kept moving back and forth, hitting the keel bone and making a "bang bang" sound.

But the keel is unmoved and has no intention of being damaged at all.

Seeing this, the administrator raised his eyebrows.

Last time at 100 kilograms, the wood made a "crack" breaking sound instantly, but in just one day, the tolerance of this wood has made such a great progress?

It seems that these students are just talking.

The management moved in his heart and silently increased the impact.

One hundred and fifty kilograms.

Two hundred kilograms

Two hundred and thirty kilograms

The impact strength is increasing bit by bit, but the keel is still as stable as an old dog.

Apart from the slight dent on the impact surface, there is no other "damage" in the entire keel.

On the side, the students in Class 9 held their hands tightly, and light burst out in their eyes.

There was a suppressed look of excitement on his face.

After so long, they finally made a possible qualified keel!

Although it is only 230 kilograms at present, it is still far from their expected goal.

But at least this path is right!

“Do you want to add it again?”

"This wood is already very good. If you add it, it would be a pity to damage it."

The administrator paused the impact and looked at the students in Class 9 as if inquiring.

After a brief silence, the students in Class 9 looked at each other and Wang Yu nodded heavily:

"add!"

"Really?" The administrator frowned slightly, and without saying anything, he continued to ask, "How heavy?"

"Three hundred kilograms, full weight!" Wang Yu replied.

Three hundred kilograms are the maximum amount of this impact equipment.

This time, Class 9 wants to come to Boda University and verify their efforts in recent days.

Wang Yu also wanted to see if the things he planned could be realized.

After a moment of silence, the administrator saw that Class 9 was still unmoved and could only start the device silently.

The impact was raised to 300 kilograms.

The speed of the iron pillar increased sharply, and with a trace of afterimage, it blasted towards the "keel bone".

A rumble of friction sound came out.

It seemed that the tolerance limit of the 'keel bone' was reached, and the entire keel began to tremble slightly.

Like the previous few times, this is a sign of falling apart.

The entire Class 9 couldn't help but hold his breath and stared at the keel that was hitting the stage.

Management showed a regretful expression.
