A Ton of Superman

Chapter 147: Young's modulus

Will this strange phenomenon cause domestic athletes not to be aggressive? Focus on domestic events?

There must be such a possibility. There have been active national athletes preparing for the National Games. No one was willing to go to the World Championships. As a result, only two teams were sent to participate in the World Championships.

One can make a lot of money, the other can only earn a subsidy at most, and you can imagine which event you choose to participate in.

However, for top athletes like Liu Xiang, he can win the championship in high-profile games such as the World Championships and earn more money than the National Games, so he will naturally choose to participate in high-profile games.

Perhaps this statement would be too utilitarian for the athletes, but that is the general atmosphere right now.

Not to mention athletes, it is an ordinary people in other industries.

There may be hundreds of thousands of domestic competitions, but no money for international competitions. Presumably, eight out of ten people will choose to participate in domestic competitions.

Yi Dun is not a fairy who does not eat fireworks on earth, he certainly wants to make money.

The money earned is glorious and the conscience earned is not a shameful thing.

...

Everyone laughed when he heard that Yi Dun wanted to report more events at this national track and field championship.

"Report it. The more you report, the better. We expect you to refresh most of the track and field records in China." Director Xu smiled.

"By the way, I heard that you don't have your own pole now. This month, you can customize a pole, I will let someone contact you."

Yi Dun nodded his head, the pole thing is really a big problem. When the game is over, why don't you borrow someone's pole pole?

I do n’t want to borrow it. For the time being, the length and thickness of the poles of different athletes are different. The borrowed poles may not be used smoothly, which may affect their performance.

As for his own exclusive pole, Yi Dun actually has a vision in mind.

The brace materials of the current international competition are roughly divided into two types.

One is a carbon fiber rod and the other is a glass fiber rod, both of which are used by athletes.

The struts borrowed by Yidun were all fiberglass. The struts of this material gave Yidun a bad feeling.

The elasticity is too strong and too easy to bend.

For those high-level pole vaulters, bending too easily is naturally not a problem, but an advantage. They can use the flexibility of fiberglass to borrow more force.

And Yi Dun's stinky style, if the elasticity is too strong, it is more likely to cause mistakes.

So Yi Dun decided to customize the carbon fiber rod. The Young's modulus of this material is three times that of glass fiber, which is more suitable for you.

The so-called Young's modulus is a concept of physical material mechanics.

The larger the Young's modulus, the less likely to be deformed.

Yi Dun ’s eight-point physics naturally did n’t know what Young ’s modulus was. He also heard it from Liu Lei.

Anyway, this carbon fiber rod is harder. Although the elasticity is not as good as that of glass fiber, does Yi Dun still need to borrow this power?

What he needs more is that the pole is stable enough to allow him to cross the bar in mid-air steadily.

...

After the internal meeting was over, someone contacted Yi Dun, a staff member in charge of equipment at the training base.

When I heard the price of the pole, Yi Dun was speechless. The fiberglass pole is cheaper, but it is also a price between 3,000 and 5,000.

Carbon fiber rods are more expensive, with a base of five thousand, and more expensive tens of thousands ...

There are no pole manufacturers in China, and all have to find foreign manufacturers to customize, which is naturally ridiculously expensive.

The key to this thing is not just to prepare one shot. The breakage of the pole during the pole vault will occur almost every year, so the average pole vaulter will prepare three to five poles when he participates in the competition.

Since decathlon only has three chances to try to jump, it doesn't need so much, but you have to buy a two shot to prevent accidents.

Yi Dun is about to cry. Can't he buy bargains? You must pick up the more expensive customization.

If you customize two shots, you can't beat 20,000 yuan ...

The key to this money is that Yi Dun has to pay for it.

If you are an athlete within the system, then the country will definitely pay for help in customizing.

But Yi Dun is now outside the system. Even if he wants to help him customize it, he is probably embarrassed to agree.

In a flash, Yi Dun more deeply realized the meaning of the phrase "poor text and rich military".

Without entering the system, how many families are willing to pay so much to buy poles.

...

All of Yi Dun's previous savings were used to buy a house, and now there is more than 20,000 yuan on hand.

There was no way to call the second uncle, took 30,000 yuan from him, and then gave it to the staff, let him help customize two carbon fiber rods.

All the 30,000 yuan was given to others, and more was paid back.

This time when I came to the training base of the National Training Team, Yi Dun was assigned to the previous dormitory, but this time I live alone.

At eight o'clock the next morning, someone knocked on Yi Dun's dormitory door.

After opening the door, Yi Dun showed a smile on his face. It was none other than the old acquaintance Gong Lijiao.

"Yidun, hurry and follow me. At our training base, more than a dozen national team coaches are already noisy!" Gong Lijiao said oddly.

Yi Dun was stunned. The coach was so arguable that it had nothing to do with himself ...

"Hmm? Is it wrong, what did I do?" Yi Dun asked, scratching his head in doubt.

"It's not all because of you. Now everyone in the circle knows that you guys are going to break the world record, and the coaches naturally want to put you back."

"Now they are arguing about this matter, you may not know what this means for coaches, it is very important anyway."

"Now hurry up with me, coach Pan of the decathlon is about to cry ..." Gong Lijiao said with a wry smile.

Yi Dun was dumbfounded and probably knew what was happening in an instant.

Following Gong Lijiao to the conference room of the training base, Yi Dun found Gong Lijiao exaggerated after entering the door.

There is no quarrel ~ www.readwn.com ~ I only saw more than ten coaches sitting there and all said nothing.

Coach Li Meisu, who taught Yi Dun, was among them.

Seeing Yi Dun coming, all the coaches showed a "gentle" smile on their faces.

"Yidun is here? Come and sit down."

"Sit on my side. Let's have a good chat with our grandfathers. We have known your name for a long time.

"Good boy, it looks like a personal talent. No wonder he can make such achievements."

"Yidun, my hometown is Qinglian City, we are also considered half-townships. Come here, we will talk about it.

Yi Tun twitched, are these people really coaches of the national team? Doesn't it mean that the coaches of the national team are very strict?

These people look gentle like the old lady next door.
