Although the mechanics of the mecha's legs are more complicated for the average person, as far as Zhang Xiaojiang is concerned, this problem is even simpler than the first one.

"The mechanics involved in mecha include: material mechanics, plastic mechanics, elastic mechanics, viscoelastic mechanics, structural mechanics, solid mechanics, fluid mechanics, rheology, aerodynamics, hydraulics and soil mechanics.

However, in mecha motion, mechanics is mainly divided into the three laws of collision, orbit theory and lever mechanics.

The first article of the law of collision: the motion of two objects must have the resultant force of the action of the third object and the object above the third object, the object with the greater mass forms the center of mass, the object with the small mass orbits around the center of mass, and the center object rotates slowly.

The second article of the law of collision: the motion of many objects should have the resultant force of the action of the third object and the object above the third object, the objects produce a resultant force with each other, they cannot form a center of mass, the objects orbit around their common center of gravity, and the objects falling into the center of gravity rotate at high speed.

Article 3 of the law of collision: the motion of multiple objects must still have the resultant force of the action of the third object and the objects above the third object, the object with the greatest mass forms the center of mass, the other objects orbit around the center of mass, and the center object rotates rapidly.

Orbit theory refers to the orbit of an object, which moves under the influence of the resultant force, and when the resultant force increases, the orbit moves outward, and when the resultant force continues to increase, the two objects separate. When the resultant force decreases, the orbit moves inward, and when the resultant force continues to decrease, the smaller object crashes into the larger object.

The lever mechanics used on the mecha mainly refer to the lever mechanics of the human body, while the lever mechanics of the human body are mostly laborious levers....."

Regarding the mechanics of the mecha, Zhang Xiaojiang talked about it in a paragraph, perhaps this kind of mechanics is mainly macroscopic physical mechanics, which is easy to understand and memorize, so he is very familiar with this knowledge point.

The so-called palladium element and other material knowledge points before are less contact for a college student, but they are like a book from heaven.

It took Zhang Xiaojiang five minutes to briefly explain the mechanical composition of the mecha's legs, and Lin Feng nodded with satisfaction with his answer.

I have to say that Zhang Xiaojiang has a very firm grasp of knowledge points, and many of the things he answers can be found in the textbooks.

"That's a good answer!" Lin Feng nodded, "Then I'm asking you the third and last question...."

Ding Ding Ding....

At this moment, Lin Feng's phone rang.

It was Lin Guoxiang who called.

"Xiaofeng, what are you busy with?"

"Eat!" Lin Feng replied, and then asked suspiciously: "Old general, has the new material been successfully researched?" ”

The mining of ore on Skull Island has begun, but at the same time, there is also the research of new materials, after all, for a yttrium elemental isotope, it is necessary to understand its atomic structure and various characteristics, and then through thousands of experiments, to study the most suitable ratio with other materials.

This is a complex project.

But for a behemoth like the South China Sea Branch, it is not so complicated, after all, this is only an isotope, not a new element.

"Haha, how can it be so fast! Experts say that it will be necessary to wait at least next month for accurate results, and that it will take at least three months for the new material to be officially put into production. ”

"I called to say something else." Lin Guoxiang paused on the phone, "[Tiger Guard] has been repaired." ”

In three months, [Tiger Guard] has been repaired by the North American branch, Lin Guoxiang's meaning is to let Lin Feng go to the North American branch and drive [Tiger Guard] back to the South China Sea branch.

"Okay, I'll come to the South China Sea branch after dinner, and then I'll go to the North American branch!"

Hearing Lin Feng's answer, Lin Guoxiang was very surprised: "Eh, so positive? ”

In the past, Lin Feng's work, especially the things he wasn't very interested in, had to be delayed for a long time.

"Well, get it back early and finish it early! That's it! ”

Hanging up the phone, Lin Feng didn't continue to ask, he looked at Zhang Xiaojiang with an expectant face, and suddenly had a plan in his heart.

"Zhang Xiaojiang, the third question, I won't take the test for the time being, are you interested in going to the North American branch with me to drive a real mecha?"

"Ahh When Zhang Xiaojiang heard this, he was suddenly surprised and couldn't close his mouth, and his speech collapsed on the bridge of his nose, and he forgot to push it. "Mecha?"

"Yes, a real mecha, my students, can't just sit in the classroom and listen to the book of heaven, they have to go to the mecha and experience it on the spot."

After Lin Feng was ready to take Zhang Xiaojiang to the mecha, he saw the real thing, and then came up with a question that was not in the book, and relied on Zhang Xiaojiang to dig out the answer by himself.

"By the way, what's your nerve strength value?"

“460！” Zhang Xiaojiang, who reacted, replied loudly to this number, and his red face made him feel a lot more confident.

Because of this value, it ranks second in the mecha university, and many mecha pilots have not been able to reach this number, so after testing the nerve strength, many instructors have suggested that Zhang Xiaojiang learn mecha driving.

But after Lin Feng heard this number, he didn't show a shocked expression like the school teacher, but looked a little disappointed.

"It's a bit low, but it's not bad!"

A bit low? Not bad?

Hearing Lin Feng's evaluation, Zhang Xiaojiang was a little confused.

He heard that a real mecha pilot, after various trainings, has a peak nerve strength of only 500, and even scientists believe that 500 nerve strength is already the limit of human beings and cannot be improved.

But he himself has not undergone professional training as a driver, and his nerve strength is 460, which is already very high, if he is professionally trained, those teachers estimate that Zhang Xiaojiang's final nerve strength value may exceed 490, making him one of the best drivers.

But what Lin Feng meant by this seemed to be disgusting with the nerve strength value of 460, which was still low?

"Professor, what's your nerve strength value?" Zhang Xiaojiang couldn't help but ask in a low voice.

Lin Feng took a bite of food and recalled, "It seems that the last time I drove the [Tiger Guard], it was close to 3,000."

"What, 3000?" Zhang Xiaojiang was surprised, and the chopsticks overturned the plate.

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

"The monster won't appear until five months away!"

"I don't know the exact location of the invasion for the time being!"

"Rest assured, your cruise ship is safe in the Pacific Ocean!"

......

Dr. Newton hung up the phone, breathing a sigh of relief.

The call came from Faulkner, because Faulkner's first cruise ship had already set sail two days later, from Rakusanji to Kyushu.

In order to ensure the safety of the route, Faulkner called Newton to confirm that there was no conflict between the time of the monster invasion and the cruise ship's voyage.

After all, it's been three months since the Battle of Los Angeles, and now there is a possibility that a monster can emerge from the bottom of the sea at any time.
