Chapter 62 Making a Balance (3)

"The length of the beam affects the sensitivity, which only appears when the quality of the items in the tray is poor." Cheng Jinzhou scratched on the paper: "My design can avoid Open this situation."

In the 21st century, what he talks about is very common knowledge of physics. When he occasionally pretends to be a teaching assistant to teach his instructor, these are all things that he has to read. From the perspective of modern physics, they are just old-fashioned stuff.However, Liu Bin and Wu Zong listened carefully, and the former was still silently calculating Cheng Jinzhou's formula in his heart.

"Let's replace the metal beam first." Cheng Jinzhou picked out an iron bar from the table, handed it to Wu Zong, and said, "Can you drill out the eyes?"

Wu Zong stroked his beard, looking worriedly at the iron bar long from his thumb, he didn't have a suitable star array to complete the work.

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

Lu Xu groaned dissatisfiedly, but still stretched out a finger, found the right position and drilled on the iron bar, and saw that the place where his finger touched was slightly red, and the iron bar was like plasticine. It penetrated deeply.

"Thermal energy star array." Lu Xu bulged his biceps.

"Then let's get out all these dozen." When there was good labor, Cheng Jinzhou didn't want to let it go.

Liu Kuang stroked his beard and looked at the formula Cheng Jinzhou listed.The leader stopped working, and Wang Linghe and Xiang Xin also surrounded him. Wu Zong and his two apprentices were as excited as monkeys on drugs. They wanted to jump but couldn't. They squinted their eyes and wanted to sleep. Hazy and full of fantasy.For them, demonstrating work in front of a fourth-level star warlock is like a small company commander meeting an army commander, and it feels like awarding an honor.

"If you have time in the future, it's better to change it to a hollow one." Cheng Jinzhou commented.The iron bar used as the experimental material is finely crafted, without even a burr on the surface, let alone rust spots, etc. With the current production efficiency, it can be imagined that the price must be very strong.

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

Cheng Jinzhou smiled and said, "It's not that difficult. A better balance 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.

As Cheng Jinzhou spoke, he began to sort out the parts in his hands. Every time he wanted to modify something, he could just say a few words. Lu Xu also became a manual machine tool and helped him modify it in real time.Controlling the size of the weights and determining the accuracy of the weights is a matter of minutes, and its convenience is enviable.

Wu Zong has simply become a helper. Of course, he is the happiest working out of several people. He must be very angry if he is asked to leave now.

With the help of a genuine star warlock, Cheng Jinzhou's combined balance is also very fast, that's all, he used standard weights to calculate the accuracy, and the data is accurate to two decimal places.

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

People have been dealing with errors this way since the 20th century.Cheng Jinzhou curled his lips, and took out the best balance among them, and said, "Wang Ling Crane Star Warlock, thank you for your materials, this balance will be given to you."

The balance with an accuracy of 0.07 (Note 1) is already very difficult to buy in star warlock stores, Wang Linghe did not refuse, reached out and took it with a smile: "Looking at your research on torque, it is still very instructive. "

"Where?" Cheng Jinzhou smiled. When it comes to physics, he can't remember many specific places, but although there is only one volume of "Mechanics and Measurement" that he got from the library last time, he can understand the details in details. It is a piece of cake to copy the contents of it and write one or two papers from hundreds of years ago.

"I'll take the rest back and make it." Seeing that it was getting late and the parts had been roughly cut by the humanoid machine tool, Cheng Jinzhou stood up with a smile and said goodbye. At least fifteen or six balances of materials were more than enough to make the loan.

Xiang Xin stood up hurriedly and said, "Let me sort out the results of this research for you."

"Uh... how embarrassing this is." After all, the contribution points of the association are very valuable things. He is not yet familiar with the format of the paper, so it would be great if someone could help.The corresponding content of moment is not valued by Cheng Jinzhou, after all, it is just a small branch of an era.

Seeing that Cheng Jinzhou didn't refuse, Xiang Xin sat down with a smile on his face. It didn't 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 you can learn more.

Liu Kuang didn't mind taking "private work" on his own land at all, and he sent Cheng Jinzhou and others out of the house with a smile, and specially instructed: "Remember, we will set off early in the morning the day after tomorrow."

Cheng Jinzhou thanked him again.

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

Discussion is false, Latin is true.Wu Zong didn't mind either, staying up late was commonplace for astrologists, if they could learn something, it didn't matter if they were tired.

……

It was already midnight when we got home, and the candlelight was still on in the study, Cheng Jinzhou felt a little guilty, first went to settle down Wu Zong with Shi Yan, and then walked over gently by himself.

"Father." Gently pushing the door open, it was Cheng Yun'an reading a book under the lamp.

"Your mother is going to bed first." Cheng's father put a bookmark in the book and put it on the table and asked, "Have you said goodbye to Mr. Liu Kuang?"

"They will also set off to the capital the day after tomorrow and invite me to take the airship together."

Cheng Yun'an was stunned for a while, and then she had plastic surgery and said, "I won't bother you."

"No." Cheng Jinzhou shook his head firmly, choosing between the plane and the carriage, he was absolutely firm.

"If I'm with the four astrologers, I'm much more at ease. After arriving in the capital, don't cause trouble, and keep a low profile." Cheng's father paused, and said in a serious tone: "What you did in Hongrizhuang , not advisable. Yunquan has been playing around for a while because of your affairs."

Cheng Jinzhou was silent, he beheaded the garrison captain in Hongrizhuang, and put it in other counties, the army would have rushed forward.But as a member of the Cheng family, Chang Shi Cheng Yunquan would definitely not allow such things to happen, and the task of suppressing them was not easy.

Cheng's father sighed and said, "Go to bed early, don't think too much, I'm going to sleep too."

"Yes." Cheng Jinzhou bowed slightly and exited the house with a slightly heavy expression.Before the murder, he was very angry; when he killed, he was very decisive; after the murder, looking back, he couldn't help feeling a little depressed.For a young man with a normal mind who grew up in a peaceful environment, hacking others to death with his own hands is not so easy.

Shi Mo was waiting at the foot 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." Cheng Jinzhou grinned, realistic plans always come first.

Note 1: The precision balance is Bird's balance.
