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

"I'm only responsible for helping with some details."

In this regard, the students could only silently compare their middle fingers, and took out the design drawings drawn by Xu Kai during the nap time after the meal and began to analyze them.

After a period of brainstorming and data inquiry, they temporarily divided the shipbuilding into three steps.

Skeleton, outline, and final shaping.

Follow these three steps, even if you make a mistake in the middle, there is still enough room for modification, so you won't have to start all over again.

And this first and most important step is the skeleton.

As the support of the whole ship, the skeleton must be rigid enough, and at the same time the weight it bears must be perfectly distributed.

Only in this way can the whole ship reach the navigable goal.

This point is not difficult with Wang Yu's calculation blessing.

In the skeleton, the most important thing is the keel.

It can be said that the keel is the core of a ship, which is equivalent to the backbone of the entire ship. All the scattered constructions all have their roots in the keel.

All decks, cabins, bows, and rudder wheels emanate from the keel.

After a brief struggle, the students in Class Nine decided to start with the keel first.

Only when this thing is done, can they carry out the subsequent division of labor according to the specifications of this main line.

Otherwise, it is useless to say anything.

Do it when you think of it.

At this moment, Class Nine's executive power was displayed again.

I saw that after they picked out a suitable piece of wood, they took the electric saw and prepared to cut it according to the mark just drawn.

The keel, as the old saying goes, is actually a long and straight crossbar.

Just cut out the shape the way they want it and polish it and you should be fine.

However, just as they were about to strike.

Immediately there was an exclamation from the side:

"Who the hell, put the damn chainsaw down!"

The students heard the sound and looked around, only to see Ren Yan running over in a panic with a face full of panic.

What's wrong with my teacher?

Burned ass?

The students in Class Nine were a little puzzled.

Just about to ask a question, Ren Yan turned off the power without saying a word, snatched the chainsaw from a classmate, and said angrily:

"Is this how you play with chainsaws!?"

"The whole person is holding the chainsaw straight, planning to cut in with brute force?!"

"Aren't you afraid that if you are not careful, you will be disabled for life?!"

"I originally thought that your plan this time was quite sufficient! Everything that should be considered has been considered!"

"But the most basic security link, why didn't you think about it at all?!"

"A chainsaw can be used for anything?"

"It's still this extra-large chainsaw!"

"Even if it's an angle grinder, doesn't it have to be protected? Let alone a chainsaw!"

"Do you want to die or not to live!?"

The students were taken aback by Ren Yan's angry words, they could tell that their teacher was really angry.

But the chainsaw...

Isn't the saw finished when the electricity is turned on?

Have other questions?

Seeing the expressions of her students, Ren Yan sighed heavily inwardly.

These guys really don't realize this...

Helpless, Ren Yan could only demonstrate in the manner of the student just now.

I saw Ren Yan holding the handle with both hands, standing straight with her lower body, bending slightly at the waist and cutting down on the wood in front of her.

Then in his demonstration, the phone 'slid' across the wood in an instant, and finally 'cut' to his leg along the inertia.

Immediately, Ren Yan picked up the chainsaw again and looked around:

"did you see it?!"

"This is what will happen when you use the chainsaw like this, and it's because the teacher didn't turn on the electricity just now."

"If this is electrified, what do you think will happen?"

"A chainsaw cuts so fast that the resistance of the wood is almost negligible."

"You guys are still holding it with both hands, cutting down desperately, who else can you cut?!"

"Can't you read the manual before using it?"

Ren Yan glared at the students bitterly, then turned on the power to the chainsaw again. After pressing the button, the humming sound came out again.

He started a new demo.

"Look, this is how the correct chainsaw is used!"

"At the very least, to keep your body stable, it's best to form a triangle with the ground, and it's not a big problem to squat or stand."

"But be sure to turn sideways to the direction of the chainsaw, and don't start sawing with the chainsaw in front of yourself."

"At the same time, the handle of the chainsaw can be held with one hand, and the other hand should hold the raised position above the handle."

"This is where your second hand should be grasped, so that you can effectively control the chainsaw so that it doesn't go astray."

As he said that, Ren Yan tapped the small holding point on the top of the chainsaw, and then took the chainsaw and sawed down the wood in front of him.

The wood snapped at the sound, and at the moment of breaking, Ren Yan's upper forearm exerted force to stop the chainsaw in the air, and the other hand pressed the power at the same time.

The chainsaw has returned to calm.

"See, this is the correct posture for using a chainsaw."

"Be sure to remember to press the power button immediately after sawing once, don't feel troublesome, all this is for safety considerations."

"Not only for you, but for others!"

"Think about it, if you don't stop wanting to continue sawing after sawing one place, lift the chainsaw like this..."

"It just so happens that there is a person standing in front of you, what will happen?"

"And this person is very important to you?!"

With that said, Ren Yan looked at Wang Bo.

"Wang Bo, for example, Xia Yue is standing in front of you?!"

Hearing this, Wang Bo was taken aback for a moment, and then shivered subconsciously.

There were still some things that he thought he would do more, but he left them behind in an instant.

'This power supply must be pressed! '

When the other students saw their teacher giving such an example, they also nodded with sympathy.

This will make them Wang Bo.

If this kind of tragedy is really going to happen, I'm afraid my mentality will collapse immediately...

'For your own physical and mental health, it is better to listen to what the teacher says. '

The students immediately convinced themselves in their hearts.

But the corners of the netizens in the live broadcast room twitched for no reason.

Why is Mr. Ren’s example always so scary...

And this habit of using my own students to make it up, isn't it a bit too skilled...

This is the first time.

Don't you know how scary it is?

Netizens frowned, pursed their lips, and thought about themselves.

Suddenly there was a shiver.

This thing really happened to me, who can stand it!

Sometimes it's better to saw yourself!

As for the judges, after being speechless for a while, they could only sigh with emotion:

"Although the example is not very appropriate, the effect is surprisingly good..."

.....

And in fact it is.

After Ren Yan gave this example, the eyes of the students in Class Nine suddenly became serious.

Honestly watched Ren Yan demonstrate the norms of continuous use of chainsaws.

After two more saws, Ren Yan turned off the chainsaw and put it away:

"This is the last step."

"A chainsaw is no better than other tools. Even if the power is cut off, it can't be misplaced. It must be put away, understand?"

The students nodded.

Only then did Ren Yan clap her hands, and returned to her chair in satisfaction.

Continue to watch.

The students picked up the chainsaw again according to Ren Yan's method, and prepared to deal with the keel.

But the moment they picked up the chainsaw and were about to cut, they suddenly froze.

Looking at the shattered wood in front of him, he wanted to cry but had no tears.

'The keel wood we finally picked out!

!

'

Chapter 264 The Keel Problem

After a moan.

The students in class nine could only put away their depressed hearts and start looking for new 'keel' wood in the vast woods again.

The keel is no better than others, and the quality requirements are much higher.

The first is length and width.

Thick, long, and hard are the first elements.

And for the convenience of the follow-up, it is best to have a slight curvature, which is the most suitable keel.

It took them a long time to find the root they found before.

But I was 'taught' by my own teacher.

They can only search again.

Fortunately, with the first experience, it is not very difficult to find it again.

Soon, Class Nine found another piece of wood that was useless.

The species is fir.
