"But!" Lin Feng took the conversation, "It is difficult to make a spring applied to the mecha.

The largest spring currently is used on the aircraft carrier spring repetitive catapult. Its steel wire diameter is 150mm, the spring diameter is 550mm, the pitch is 288mm, and the length is 3980mm. The material is nickel-chromium steel in alloy steel.

Nickel-chromium steel has an elastic modulus of 206Gpa, a shear modulus of 79.38Gpa, and a Poisson's ratio of 0.25-0.3. It is the best spring material except superalloys.

Even if the superalloy spring is made, it is not much larger than this data.

The compressive resistance of this spring is only 15,600Mpa. If used for load bearing of mechas, at least 3,000 such springs are needed to form a spring group to support the self-weight of the mechas.

However, the cross-cutting area of ​​the three thousand spring groups exceeds 600 square meters. If arranged and combined, the layout area of ​​the three thousand spring groups is no less than 1,000 square meters.

But it is impossible for mecha to make thousands of square meters of feet out.

Therefore, if you want to install a spring on the mecha, you must start from the spring performance, and there are four main reasons that affect the spring performance.

1. The diameter of the spring wire, 2. The diameter of the spring, 3. The spring pitch or number of turns, 4. The elastic modulus of the material.

The first three problems are easier to solve, but the most critical one is the last problem. The elastic modulus of the material.

Nickel-chromium steel has an elastic modulus of 206Gpa and super alloy has an elastic modulus of 265Gpa. These two are the best materials for making springs, but they are far from meeting the spring standards required by mechas.

So now a new material is missing, a new material used to make springs!”

Lin Feng finished the related questions in one breath, then looked at Zhang Xiaojiang and asked, "Is it right?"

Zhang Xiaojiang nodded suddenly, "Yes, you are so right! May I ask you..."

"He is..." Cao Wenyan was about to introduce him, but was interrupted by Lin Feng.

"I am a teacher at Mecha University, my surname is Lin, hello, Zhang Xiaojiang!"

"Hello, Teacher Lin!" Zhang Xiaojiang stretched out his hand enthusiastically, held it with Lin Feng, and then looked forward to asking: "Teacher Lin, can I ask a few questions?"

"no problem!"

Lin Feng refused everyone. He liked the person in front of him very much, because in Zhang Xiaojiang, Lin Feng seemed to see his shadow back then.

However, Cao Wenyan interrupted the two: "Zhang Xiaojiang, do you ignore your cousin?"

In fact, he wanted to say that this is an office, not a place for both of you to answer questions.

Hearing Cao Wenyan’s reminder, Zhang Xiaojiang slapped his forehead and suddenly realized.

He seemed to have forgotten about his cousin's affairs.

But Lin Feng suddenly interrupted and asked, "Tell me what's wrong with your cousin, maybe I can help."

Hearing this, Zhang Xiaojiang seemed to have caught a life-saving straw and said in a hurry: "My cousin is an anchor. Because he hindered public security, he was arrested and put in a detention center!"

Well, it is not too big for hindering public security. This crime is not too big or small. Lin Feng doesn't understand much, but he can find Lin Guoxiang to understand the situation.

"What's your cousin's name? I'll ask someone to ask!"

"Guan Xiaoai!"

Lin Feng was a little confused when he heard this name. Isn’t this saving the anchor?

It's such a coincidence?

Didn’t I give her 20 million, why did I go to commit a crime? I was also arrested and put in a detention center.

This is a bit tricky. You must know how Guan Xiaoai committed a crime. If the circumstances are serious, you may not be able to help him, so Lin Feng did not say anything to death.

"Okay, I understand. You can go back first. I'll ask you about the specific situation. If the problem is serious, I probably have no choice!"

"Teacher Lin, no matter what the result is, I want to thank you!" Zhang Xiaojiang was grateful again and again before leaving the principal's office.

At this time, Lin Feng also said goodbye to Cao Wenyan: "Principal Cao, then we will go back first!"

"Okay, okay, Director Lin comes to the school more often when he has time to give lectures to the students!" Cao Wenyan respectfully sent Lin Feng out of the office door.

.............

After returning to the company, Lin Feng called Lin Guoxiang again because of the matter of keeping Xiaoai.

Lin Guoxiang explained the whole story, but did not agree to let Guan Xiaoai and the other two go, and then he said a few words.

Lin Feng did not force it. The Guan Xiaoai incident caused a huge impact, and he could not challenge the bottom line of the law for personal favors.

I have to say that Lin Guoxiang’s methods of punishing people are really good. He will not arrest him in front of him and settle the accounts afterwards.

Not only did he punish people, but he also poached Zhao Yong.

"Brother-in-law, your body has recovered almost the same thing and you don't need anyone to take care of it. Feifei can also let go of the company. I don't think I will continue to stay in the Xiaofeng Mecha Construction Company!"

Hearing this, Zhao Feifei was unhappy, "Brother, you are confused. Lin Feng has only been recuperating for twenty days, so why don't he need someone to take care of him?"

Lin Feng was very surprised: "Brother Zhao, have you received any business?"

"Hahaha!" Zhao Yong smiled, "You can't hide anything from your brother-in-law. Let's be honest. Yesterday the old general asked me to discuss a deal and asked me to be responsible for the 100,000 deep water monitor auxiliary materials. I roughly calculated that this deal can earn at least 300 million."

"What do the veteran general want the auxiliary materials for deep water detectors?" Lin Feng was even more curious.

Zhao Yong thought for a while, "It seems that the Pacific Rim Defense Organization is going to arrange a 10,000 square kilometers of floating monitoring network above the Pacific crossing port to monitor every move of the crossing port."

The last time the tail rat destroyed the maritime reconnaissance station, so this time it was normal to re-establish the reconnaissance system.

However, Lin Feng did not expect that because the investigation information of the investigation station was not comprehensive, the last time the turtle on the back of the Pacific Ocean was leaked, which made the Pacific Rim Defense Organization determined to strengthen the investigation methods. It covered the investigation network at 10,000 square kilometers above the crossing mouth.

This is a very large project, and the labor and materials required are astronomical.

No wonder Zhao Yong was so happy to be able to drink a sip of soup under such a big project.

Zhao Yong was indeed happy. With this project, all the five million he had lost to his sister and Lin Feng.

He is really glad to have taken over Lin Guoxiang's line, although he has compensated his sister.

"The project will start next month, so I have to prepare first, so for the Xiaofeng Mecha Construction Company, I am really weak!"

Now that Zhao Yong has his own business, Lin Feng can no longer force him to continue to manage his company.

"Okay, I'm fine. Brother Zhao, you have to be careful. After all, it's not absolutely safe to cross the mouth. Monsters may appear at any time."

But Zhao Yong didn't care, "Don't worry, brother-in-law, the two monsters only invaded last month. Experts speculate that after this invasion, the monsters also need a certain buffer period, and it will take at least half a year before they invade again."

Lin Feng didn't know what to say.

Experts speculate that this thing can be believed?
