Chapter 147 Young's Modulus
Will this strange phenomenon cause domestic athletes to be unprofitable and focus on domestic competitions?
There must be such a possibility. There have been athletes from all over the country who actively prepared for the National Games. No one was willing to go to the World Championships, but only the second team was sent to participate in the World Championships.
One can make a lot of money, the other can only earn a subsidy at most. You can imagine which event you choose to participate in.
However, for a top athlete like Liu Xiang, if he can win the championship in a high-standard competition like the World Championships and earn more money than the National Games, he will naturally choose to participate in high-standard competitions.
Maybe this statement will make athletes too utilitarian, but that's the current atmosphere.
Not to mention athletes, they are ordinary people in other industries.
Domestic competitions may be able to get hundreds of thousands of dollars, but international competitions cannot get money. I believe eight or nine out of ten people will choose to participate in domestic competitions.
Yi Dun is not a fairy who is not in the world. He must also want to make money.
This money is made openly and unconscienceless, and it is not a shame.
...
Everyone laughed when they heard that Yi Dun wanted to report more events at this National Track and Field Championships.
"Report, the more you report, the better. We expect you to refresh most of the track and field records in China." Director Xu said with a smile.
"By the way, I heard that you don't have your own pole yet. In this month, I'll customize a pole by myself. I'll contact you."
Yi Dun nodded. The pole stretching is indeed a big problem. If you compete, you won’t borrow someone else’s pole to use, right?
Let’s talk about whether they borrow or not. The length and thickness of the support poles of different athletes are different. The borrowed support poles may not be easy to use, which may affect their own performance.
Yi Dun actually had a vision for his exclusive pole.
At present, there are two types of pole materials for international competitions.
One is a carbon fiber rod and the other is a fiberglass rod. Both materials are used by athletes.
The struts borrowed by Yi Dun were all fiberglass, and this kind of struts gave Yi Dun a very bad feeling.
It's too elastic and too easy to bend.
For those high-level pole athletes, it is naturally not a problem to bend too easily, but rather an advantage. They can borrow more force with the elasticity of fiberglass.
If Yi Dun's stinky handle is too elastic, it is easier to make mistakes.
So Yidun decided to customize carbon fiber rods. The Young's modulus of this material is three times that of glass fiber, which is more suitable for him.
The so-called Young's modulus is a concept of physical materials mechanics.
The larger the Young's modulus, the less likely it is to deform.
Yi Dun's 8-point physics test, naturally I don't know what Yang's modulus is. He also heard it from Liu Lei.
Anyway, this carbon fiber rod is harder. Although the elasticity is not as good as glass fiber, does Yidun still need to rely on the power of such a force?
What he needs more is that the pole is stable enough to allow him to cross the pole stably in mid-air.
...
After this internal meeting was held, someone contacted Yi Dun, a staff member who was specifically responsible for equipment at the training base.
When Yi Dun heard the price of the strut, he was speechless. Fiberglass rods were relatively cheap, but they were only between 3,000 and 5,000 yuan per strut.
Carbon fiber rods are much more expensive, and a base of a rod costs 5,000 yuan, and a little more expensive is tens of thousands...
There are no strut manufacturers in China, so they have to find foreign manufacturers to customize them, so the price is naturally ridiculously expensive.
The key is that this thing cannot be prepared for only one pole. The pole breaks in pole vaults almost every year, so pole vaulters usually bring their own three to five pole pole pole when participating in the competition.
Since there are only three chances to skip the decathlon, there is no need to do that, but you have to buy two shots to prevent accidents.
Yi Dun is about to cry. He can't buy bargains, right? He must have to pick up the more expensive customization.
If you customize two shots, you can't get enough money for 20,000 yuan...
The key is that Yi Dun has to pay out of his own pocket.
If you are an athlete within the system, the country will definitely pay for customization.
But now Yi Dun is outside the system, even if he asks him to customize it, he probably feels embarrassed to agree.
In an instant, Yi Dun realized more deeply the meaning of the saying "Being poor, wealthy and martial arts".
If you don’t enter the system, how many families are willing to pay so much money to buy poles.
...
Yi Dun used all his savings to buy a house, but now he doesn’t have more than 20,000 yuan on hand.
There was no choice, so I called my second uncle, took 30,000 yuan from him, and handed it over to the staff, asking him to help customize two carbon fiber poles.
All 30,000 yuan was given to others, and the more they were refunded, and the less they were compensated.
This time, when I came to the national training team training base, Yi Dun was assigned to the previous dormitory, but this time I lived alone.
At eight o'clock the next morning, someone rang the door of Yidun's dormitory.
After opening the door, Yi Dun showed a smile on his face. He was neither someone else, but his old acquaintance Gong Lijiao.
"Yidun, hurry up and follow me. More than a dozen national team coaches in our training base are already quarrel!" Gong Lijiao said with a strange expression.
Yi Dun was stunned. The coach was quarreling, what did it have to do with him?
"Well? Did you make a mistake? What did I do in the past?" Yi Dun asked in confusion.
"It's all because of you. Now everyone in the circle knows that you are going to break the world record steadily, so the coaches naturally want to take you under their will."
"This is what they are arguing now. You may not know what this means to the coaches. It's very important anyway."
"Now, hurry up and go with me. The decathlon Coach Pan is almost crying..." Gong Lijiao said with a wry smile.
Yi Dun was stunned and instantly understood what was happening.
Following Gong Lijiao to the conference room of the training base, Yi Dun entered the door and found that Gong Lijiao was a little exaggerated.
There was no quarrel, only more than a dozen coaches were seen sitting there and all of them kept silent.
Among them, Coach Li Meisu, who taught Yi Dun, was among them.
Seeing Yi Dun coming, the coaches all showed "gentle" smiles on their faces.
"Yidun is here? Come and sit down."
"Let's sit by my side, let's have a good chat. We have known your name for a long time and have never had the chance to meet."
"Good boy, it looks like a talent, no wonder he can achieve such a result."
"Yidun, my hometown is from Qinglian City. We are half a fellow villager. Come here quickly and our fellow villager will have a good talk."
Yi Dun's mouth twitched. Are these people really all national team coaches? Didn't it mean that national team coaches are very strict?
