"The length of the beam affects sensitivity, and that's when the poor quality of the items in the pallet is high." Cheng Jinzhou scratched on the paper: "My design can improve the position of the center of gravity and the selection of the knife edge through guò to avoid this situation." ”

In the 21st century, all he said was very common physics knowledge, and occasionally when he pretended to be a teaching assistant to teach for his tutor, these were all things to be recited, and from the perspective of modern physics, they were just old-fashioned goods. However, Liu Bin and Wu Zong listened very carefully, and the former was still silently calculating Cheng Jinzhou's formula in his heart.

"Let's put on the metal beams first." Cheng Jinzhou selected an iron bar from the table and handed it to Wu Zongdao: "Can you drill out of the eye?" ”

Wu Zong stroked his beard and looked at the thumb-length iron bar with some worry, he didn't have the right star array to complete the job.

"Let Lu Xu come." Liu Kuang grabbed it and said, "This seems to be a step further than the results you submitted to the association last time. ”

Lu Xu snorted twice dissatisfied, but still stretched out a finger and drilled it into the iron bar in the right place, and saw that the place where his fingers touched was slightly red, and the iron bar was like plasticine, and it was deeply inserted by his fingers.

"Thermal Star Array." Lu Xu puffed out his biceps.

"Then let's get out of the dozen or so." When there is good labor, Cheng Jinzhou doesn't want to let go at all.

Liu Kuang touched his beard and looked at the formula listed by Cheng Jinzhou. The leader stopped working, Wang Linghe and Xiang Xin also came around, Wu Zong and his two apprentices were excited like a drugged monkey, wanting to jump but not jumping, squinting and wanting to sleep, and hazy and full of fantasies. For them, demonstrating their work in front of a fourth-level star warlock is tantamount to meeting the commander of a small company in person, and it feels like a decoration.

"If you have time in the future, it's better to change it to a hollow one." Cheng Jinzhou commented. The iron bar made of solid yàn material is finely made, and there is not even a single burr on the surface, let alone rust spots, etc., with the current production efficiency, it can be imagined that its price must be very strong.

"It's hard to control the quality of the hollow." Putting down her research work, Xiang Xin once again turned into a curious baby.

Cheng Jinzhou smiled and said: "It's not that difficult, the better balances should be hollow." ”

Judging from the current balance design of the Great Xia Dynasty, the sensitivity of the balance is related to the length and weight of the beam. Gentlemen with good craftsmanship will definitely think of making hollow metal beams.

Cheng Jinzhou said as he spoke, and began to sort out the parts in his hands, and every time he wanted to modify it, he could say a few words casually, and Lu Xu also became a manual machine tool to help him modify it in real time. Controlling the size of the weight and determining the accuracy of the code are all matters of minutes, and its convenience is enviable.

Wu Zong has purely become a layman, of course, he is the happiest of several people, and he has to be angry to let him go at this moment.

With the help of a genuine star warlock, Cheng Jinzhou's combination balance was also fast, and he used standard weights to calculate the accuracy, counting jù to two decimal places.

Even Liu Kuang nodded when he saw it: "If you use it like this, you will know how much error there is." ”

Since the 2o century, people have been dealing with errors in this way. Cheng Jinzhou pursed his lips, turned to take out the best balance among them, and said, "Wang Ling Hexing Warlock, thank you for your materials, this balance will be given to you." ”

Balances with an accuracy of O.O7 (Note 1) are already hard to buy in the Star Warlock Store, so Wang Linghe didn't shirk it, reached out and took it and said with a smile: "Looking at your research on torque, it's still very enlightening." ”

"Where." Cheng Jinzhou smiled, if you want to talk about the content of physics, he can't fully remember many specific places, but although there is only one volume of "Mechanical Metrology" that he got from the library last time, he can give a good supplement to the details, and it is naturally a piece of cake to copy the content and write one or two papers hundreds of years ago.

"I'll take the rest back and make it." Seeing that it was getting late, and the humanoid machine tool had roughly cut the parts, Cheng Jinzhou got up with a smile and said goodbye, at least fifteen or sixteen balance materials, it is more than enough to make it to repay the loan.

Xiang Xin hurriedly stood up and said, "I'll sort out the research results for you." ”

"Uh...... How embarrassing is that. "After all, the contribution point of the association is a very valuable thing, and he is not familiar with the model of the paper, so it would be great if someone helped. The corresponding moment content is not valued by Cheng Jinzhou, after all, it is just a small branch of the era.

Seeing that Cheng Jinzhou did not refuse, Xiang Xin sat down with a smile, it would not take much time to collect and sort out the research results, but he would have a deeper understanding of the contents. If necessary, you can also ask the original owner and learn more.

Liu Kuang didn't mind taking "private work" on his land at all, and sent Cheng Jinzhou and the others out with a smile, and specially instructed: "Remember that we will go out early the day after tomorrow." ”

Cheng Jinzhou thanked him again.

When he went out, he didn't let Wu indulge and said, "There are still some things I want to discuss with you." ”

The discussion is false, and Lazhuang Ding is true. Wu Zong doesn't mind, staying up late is a common occurrence for star warlocks, and if they can learn something, it's nothing if they're tired.

……

It was the middle of the night when he got home, and the candlelight was still lit in the study, Cheng Jinzhou felt a little guilty, so he went to settle down with the Yan first, and walked over gently.

"Daddy." Gently pushing open the door, it was Cheng Yunan reading under the lamp.

"Your mother went to sleep first." Father Cheng put a bookmark in the page, put it on the table and asked, "Have you said goodbye to Mr. Liu Kuang?" ”

"They will also go out to the capital the day after tomorrow and invite me to take a ride on the airship together."

Cheng Yunan was stunned for a moment, and then said with plastic surgery: "It won't bother people." ”

"No, it won't." Cheng Jinzhou shook his head firmly, choosing between the plane and the carriage, he was absolutely firm.

"With the four Astral Sorcerers, I'm much more relieved. After arriving in the capital, don't make trouble, and focus on keeping a low profile. Father Cheng paused as he spoke, and said in a stern tone: "What you do in Hongrizhuang is not advisable. Yunquan has been going around for a while for your sake. ”

Cheng Jinzhou was silent, he killed the garrison captain in Hongrizhuang, and put it in other states and counties, and the army would have pounced on it a long time ago. But as a member of the Cheng family, Changshi Cheng Yunquan will definitely not allow this kind of thing to happen, and the work of bullet pressure is not easy.

Father Cheng sighed and said, "Rest early, don't think too much, I'll go to sleep too." ”

"Yes." Cheng Jinzhou bowed slightly and withdrew from the house, his expression a little heavy. Before the killing, he was very angry; When he kills, he is very decisive; After the killing, I can't help but feel a little depressed when I think about it. For a young man who grew up in a peaceful environment and is psychologically normal, it is not so easy to hack others to death with his own hands.

Shi Mo waited at the bottom of the steps with a lantern, and said in a low voice: "Mr. Wu Zong is waiting for you in the wing." ”

"Let's go over." Cheng Jinzhou grinned, realistic plans always come first.

Note 1: This precision balance is a bird's balance.
