"But!" Lin Feng took over, "It's very difficult to make a spring for a mecha.

At present, the largest spring is a device used for the spring compound catapult of the aircraft carrier carrier, which has a steel wire diameter of 150mm, a spring diameter of 550mm, a pitch of 288mm, and a length of 3980mm.

The elastic modulus of nickel-chromium steel is 206Gpa, the shear modulus is 79.38Gpa, and the Poisson's ratio is 0.25-0.3, which is the best spring material except for superalloy.

Even if the superalloy is made of springs, it is not much bigger than this figure.

The compressive capacity of this spring is only 15600Mpa, and if it is used for mecha load-bearing, at least 3000 such springs are needed to form a spring group to support the weight of the mecha.

However, the cross-sectional area of 3,000 spring groups is more than 600 square meters, and if they are arranged and combined, the layout area of 3,000 spring groups is not less than 1,000 square meters.

But it is impossible for a mecha to make thousands of square meters of soles.

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.

First, the diameter of the spring wire, two, the diameter of the spring, three, the spring pitch or the number of turns, and fourth, the elastic modulus of the material.

The first three problems are relatively easy to solve, but the most critical is the last one. The modulus of elasticity of materials.

The elastic modulus of nickel-chromium steel is 206Gpa, and the elastic modulus of superalloy is 265Gpa, which are already the best materials for making springs, but they are far from the spring standards required by mechas.

So a new material that is missing now, a new material for making springs! ”

Lin Feng finished the relevant questions in one breath, then looked at Zhang Xiaojiang and asked, "Am I right?" ”

Zhang Xiaojiang nodded violently, "Yes, what you said is so right!" Pls are ..... you?"

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

"I'm a teacher at Mecha University, surnamed Lin, hello, Zhang Xiaojiang!"

"Hello, Mr. Lin!" Zhang Xiaojiang stretched out his hand enthusiastically, shook it with Lin Feng, and then asked expectantly: "Teacher Lin, can I ask a few questions?" ”

"No problem!"

Lin Feng did not refuse, he liked Zhang Xiaojiang in front of him, because in Zhang Xiaojiang, Lin Feng seemed to see his shadow back then.

However, Cao Wenyan interrupted the two: "Zhang Xiaojiang, you don't care about your cousin?" ”

Actually, he'd love to say that this is an office, not a place for the two of you to answer questions.

Hearing Cao Wenyan's reminder, Zhang Xiaojiang patted his head and suddenly realized.

He seems to have forgotten about his cousin.

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

Hearing this, Zhang Xiaojiang seemed to grasp a life-saving straw, and said anxiously: "My cousin is an anchor, but she was arrested and put in the detention center for obstructing public order!" ”

Well, obstructing public order, this crime is not big, and it is not small, although Lin Feng doesn't know much, it should be no problem to ask Lin Guoxiang for help.

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

"Guan Xiaoai!"

Hearing this name, Lin Feng was a little confused, isn't this the anchor who saved himself?

How coincidental is this?

Didn't he give her 20 million in the first place, why did she still run away to commit a crime? He was also arrested and sent to a detention center.

But it's just a detention center, not a prison, so it's estimated that it won't be difficult to save her.

"Okay, I know, you go back first, I'll try to find someone to maneuver around, there should be good news soon!"

"Thank you, Mr. Lin, thank you!" After Zhang Xiaojiang was grateful repeatedly, he walked out of 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 will come to the school more often when he has time and 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 Guan Xiaoai's matter.

Lin Guoxiang promised to release Guan Xiaoai and the others, and did the same afterwards.

And he also asked PPDC TV to make an exception to recruit the three of them into the company, and the positions are war correspondents and supernumerary personnel.

Don't they like live broadcasts, then let them go to the battlefield every time they fight.

I have to say that Lin Guoxiang's means of punishing people really have a set.

Not only did he punish people, but he also had one set of digging the foot of the wall, and he poached Zhao Yong away.

"Brother-in-law, your body has recovered almost, you don't need to be taken care of much, Fei Fei can also let go of the management of the company, I don't think I will continue to stay in the small wind turbine mecha construction company!"

Hearing this, Zhao Feifei was a hundred unhappy, "Brother, are you confused, Lin Feng has only been cultivating for twenty days, why don't you need someone to take care of you?" ”

Lin Feng was very strange: "Brother Zhao, did you get any business?" ”

"Hahaha!" Zhao Yong smiled, "I can't hide anything from my brother-in-law, let's be honest, yesterday the old general negotiated a deal with me and asked me to be responsible for the matter of 100,000 deep-water monitor auxiliary materials." I roughly calculated, this transaction can make at least 300 million. ”

"What does the old general want for the auxiliary materials of the deep-water detector?" Lin Feng was even more curious.

Zhao Yong thought for a while, "It seems that the Pacific Rim Defense Organization wants to set up a 10,000-square-kilometer floating monitoring network above the Pacific crossing to monitor every move of the crossing." ”

Last time, the Tail Rat destroyed the maritime reconnaissance station, so this time the reconnaissance system was re-established, which is normal.

It's just that Lin Feng didn't expect that because the reconnaissance station's investigation information was not comprehensive, the ridged turtle slipped through the net last time, which made the Pacific Rim Defense Organization determined to strengthen its investigation methods. 10,000 square kilometers above the crossing, covering the reconnaissance network.

This is a rather huge project, and the amount of labor and materials required is astronomical.

Being able to drink soup under such a big project, no wonder Zhao Yong is so happy.

Zhao Yong was really happy in his heart, with this project, the five million he had lost when he matched his sister and Lin Feng had all earned it back.

He is really glad to catch Lin Guoxiang's line now, although he lost his sister.

"The project will probably start next month, and I have to prepare first, so, Komine Mecha Construction Company, I'm really weak!"

Zhao Yong now has his own business, and Lin Feng can't force him to continue to manage his own company.

"Okay, I don't have a problem, but Brother Zhao, you, you have to be careful, after all, above the crossing is not absolutely safe, and monsters can appear at any time."

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

Lin Feng didn't know what to say.

Experts speculate? Can this thing be trusted?

There is no way to accurately predict the time of the monster invasion, and the so-called expert predictions are just a means to appease people's hearts.
