Mr. Bai smiled: "How big is the big stone you want to carry?"
Teng Yifeng said: "It's almost two feet long and one foot wide. The whole big stone is too big. The migrant workers can't move it at all. It's really difficult for us. We are too embarrassed to ask the saint to trouble Tianzun. , I heard from the foreman who came from Gaojia Village that Mr. Bai has a way to move heavy objects."
Mr. Bai laughed: "Haha, with such a small stone, you can easily drag it away with your knowledge of physics."
The speaker has no intention, but the listener has intention.
When Song Yingxing heard this, he frowned and thought to himself: How to move such a big stone? I do know a way to make large gears out of giant wood. One is vertical and the other is horizontal. The two gears are engaged. Use an ox to drag the vertical gear to rotate and drive the horizontal gear. Then you can drag heavy objects. .
But very few people know about my method. How can a child with no hair in front of him do this? What is the physics he is talking about? Should I ask him?
Thinking of this, Taoist Master Ma in front started to greet Mrs. Bai and Mr. Bai: "Ah, aren't these Mrs. Bai and Mr. Bai? I'm a poor Taoist.
The mother and son were also very happy to see Taoist Master Ma: "Taoist Master Ma, long time no see. I heard that you went on a trip under the order of Tianzun. Are you back now?"
Ma Tianzheng smiled: "Fortunately, I have fulfilled my mission and finally fulfilled Tianzun's instructions. Tomorrow Pindao plans to go back to Gaojiacun to meet Tianzun."
Mrs. Bai smiled and pointed to the sky: "Tianzun is coming to the county now. You can see it when you look up."
Ma Tianzheng was shocked. He quickly looked up and saw a group of low clouds floating in the sky. He quickly brushed off the dust on his body and bowed his head: "Disciple Ma Tianzheng, please see Tianzun."
The low cloud rippled slightly, as if responding to him.
Ma Tianzheng was extremely happy: Tianzun responded to me!
Just as he was about to say something more, Song Yingxing grabbed his arm: "Master Ma, do you know this young man? Please recommend him to me. I have many things to talk to this young man."
Only then did Ma Tianzheng remember the important point, and quickly pulled Song Yingxing over. While introducing Mr. Bai, he was also introducing him to Tianzun: "This is Song Yingxing, Mr. Song, from Fengxin County, Jiangxi."
"This is Mr. Bai from Baijiabao.
When Li Daoxuan heard the words "Song Yingxing", he was immediately overjoyed. He's here, he's finally here, hahaha, he is the number one scientist in the late Ming Dynasty. This time he has been tricked. As long as he comes within his sight, he will definitely be there. Don't even think about leaving. There are ten thousand ways to trick him into staying.
Very good, let Mr. Bai and Song Yingxing communicate first. Although Mr. Bai has just learned physics in the second grade of junior high school, it is enough for Song Yingxing to open up a new world.
Song Yingxing hugged Mr. Bai's fists. Although he was almost thirty years younger than him, Song Yingxing still did not dare to look down upon him: "Young Master, I just heard you say that you can use physical methods to move such a big stone. I don't know. What approach are you going to take?"
Mr. Bai looked at the middle-aged man in front of him curiously. Seeing his curious expression, he seemed to be very interested in academic discussions. He couldn't help but feel happy. His physics was so fast that no one in Gaojiacun could do it. Communicate with him, and now there is someone who seems to be interested in chatting, so why don't you hurry up and start talking about it.
Mr. Bai smiled and said what he had just learned: "Gears!"
"Is it really a gear?" Song Yingxing was overjoyed: "Hey, my idea is also to use gears."
Mr. Bai: "Huh? You also know about gears? Have you studied the Physics Chapter of the Book of Heaven?"
Song Yingxing: "What is the Physics Chapter of the Book of Heaven?"
Mr. Bai: "It turns out I haven't learned it before. Huh, I was shocked. I thought there were people outside Gaojia Village who knew the Physics Chapter of the Book of Heaven. Hehe."
Song Yingxing was a little curious: "I wonder what the Physics Chapter of the Book of Heaven is?"
Mr. Bai: "I can't explain this in a few words. Let's study that big stone first."
After a while, a group of people came to the construction site outside the city and saw a huge stone in the middle of the road. They had to move the stone away or take a detour. There was no doubt that the sun would rise for the bus. If everything goes smoothly, moving the stone away is the correct answer.
Mr. Bai asked: "Have you studied the weight of this stone?"
Teng Yifeng replied respectfully: "We are not capable of weighing such a big stone. We don't know its weight."
Song Yingxing smiled and thought to himself: We can only use Cao Chong's method of weighing an elephant to weigh the stone... But the elephant can move and can catch the elephant on the boat, but the stone cannot move and cannot be moved. Even if it is put on the ship, it cannot be weighed.
As soon as he thought of this, he saw Mr. Bai take out the soft ruler used to measure clothes and measure the diameter of the big head. Then he took out a pen and paper, counted for a while, raised his head and said: "About more than 60,000 kilograms."
Song Yingxing: "!!!"
Mr. Bai continued to calculate on the paper, and after a while he raised his head again: "To move more than 60,000 kilograms of stone, at least one large gear with a diameter of XX is needed, supplemented by a small gear with a diameter of XX... I'll do the math again... Hmm... The values are almost the same. Go ask the blacksmith to make a few gears according to the dimensions I gave you. They can only be larger than the ones I ordered, not smaller than the ones I ordered. Otherwise, it will take two cows. It can’t be pulled, it’s not strong enough.”
"Put the gear on one side, use oxen to pull it, and use workers on the other side to use iron rods to tilt it, and the stone can be moved away."
Song Yingxing was shocked: I know that gears can be used to lift large rocks, but I can't accurately calculate how big a gear is and how many cows are needed to pull it. I can only make the gear as big as possible. How can this kid calculate so accurately? "
If you don't understand, just ask. Song Yingxing hurriedly asked: "Master Bai, how do you calculate how much weight can be lifted by two oxen and what gears are used?"
Mr. Bai chuckled: "The diameter difference between the big gear and the small gear can determine the multiple of their increased power... Calculate the approximate power of the two cows and the diameter difference of the two gears... Oh, this I can't explain things clearly with my mouth. I'll give you a formula and you can see for yourself.
He picked up the pen and scribbled a formula on the paper.
But Song Yingxing couldn't understand it at all and was stunned for a moment.
This is terrible. I always thought that I knew everything, but when I came here, I realized that there is a world out there and there are people out there.
"I have a merciless request, that... Physics Chapter of the Book of Heaven... I wonder if I can give it to you to read next?" Song Yingxing's face turned a little red: "I can pay you a heavy reward."
Mr. Bai doesn't care about remuneration or not. As long as someone is willing to learn, these things can be taught casually. These are Tianzun's original words. Just give me the book.
