Yang Rong and the three of them each have a new physics book.
"Force, how much force is given, how much force will be fed back."
"Give the table a punch, the more power, the greater the feedback."
"Bang!"
Yang Rong put down the book and saw that Yang Shiqi was shaking his hand and smiling bitterly.
"The official actually hit the table unconsciously, it hurts!"
Yang Rong said with a smile: "Everyone knows this truth, but they haven't summarized it, Xinghebo is really talented." ” Jin Youzi frowned and said, "I can't wait to study the scriptures hard, who would be so boring to get this?!"
” Yang Rong smiled, then lowered his head to read the book.
"Huh!
When a person walks, first of all, the foot gives a force to the ground, and then the ground feedback, and the person can move forward with the force. ” "Punching someone, the pressure is different, and the effect is different."
Yang Rong put down the book, rubbed his eyebrows and said, "This book ......"
"This book is a crooked way!"
Jin Youzi said disdainfully: "What is there to study when walking?"
And what buoyancy, boring!
” Yang Shiqi frowned and said: "This official thinks it's good, you look at his set, he can basically justify himself, and the discussion on leverage has been applied at the dock."
Buoyancy can also be applied to shipbuilding, you see his density, you can calculate the density from the size and weight of a thing, it's really exquisite!
” Jin Youzi looked at it carefully, and slowly turned a little pale.
"It's all craftsman's skills, is Fang Dehua going to change careers?"
Yang Rong saw that his expression was a little far-fetched, so he said: "Although it is a craftsman's skill, but it is a practical science, you look at this, according to his above mechanics and this pulley lever, ordinary people can make something surprising." ” …… In front of the palace in the palace, except for Zhu Gaochi's family, those palace maids and eunuchs were all surrounded by them.
Zhu Zhanji had already formed a pulley group, then hooked a chair with a hook and called Wanwan.
A pulley group composed of fixed pulleys and movable pulleys is not very powerful, and the delicate little hands are delicate, pulling the rope to pull the chair up, but waving his hand and crying out in pain.
"How many pounds?"
Zhu Gaochi asked.
Zhu Zhanji is explaining the practicality of this physics book, and in front of him stands a solid wood frame with a row of pulleys hanging in the middle.
Wanwan's pulley block only uses a fixed pulley and a movable pulley, and the row on the side is empty.
"Father, thirty-six pounds."
The weight of this big chair was very scary, Wanwan usually couldn't lift it, but today she pulled it up with a rope, and she couldn't help but be a little excited for a while.
"The county lord is so powerful!"
Liang Zhong smiled, and glared at the people next to him with threatening eyes.
Praise our family!
"Yes!
It was hard for the slave and maid to hold the chair, but the little county lord lifted it up with a rope, and it was really ......"
What is it anyway?
This person looked at Liang Zhong, his eyes were full of pleading: Big brother, the county lord Jin Zhi Yuye, do we want to praise her for her strength?
How can I marry someone in the future!
Liang Zhong also felt that something was wrong, he coughed dryly, and was about to think about other reputations, but in a blink of an eye, he saw Zhu Di.
"See Your Majesty."
"See Your Majesty."
The front of the hall immediately fell, Zhu Di squinted at the wooden shelf, and said lightly: "Get up." ” Huang Yan and the big eunuch were a little stunned when they looked at the pulley group behind Zhu Di, and Huang Yan said in a low voice: "This strange and obscene skill!
” The big eunuch didn't say anything with an expressionless face, and Huang Yan said stupidly: "I also demonstrated it in front of the palace people, and it was really ......."
"Grandpa Huang, this is the labor-saving pulley set in physics, you see, Wanwan can lift this chair with a rope."
Wanwan said proudly: "Grandpa Huang, Wanwan really mentioned it just now." ” Zhu Di walked closer and took a look: "How much effort can I save?"
” Zhu Zhanji pointed to the pulley group and said: "At present, half of the effort can be saved, if you can combine a few more pulleys, Wanwan can lift Zhan Yuan." ” "Oh!
Really?
” Zhu Di's previous impression of science was that it could impact Confucianism, and it could also allow people to learn some means of making a living.

Zhu Zhan was a little afraid to respond, but Wanwan volunteered: "Grandpa Huang, Wanwan dares!"
If you don't believe me, call the third brother to try it. ” Zhu Di was a little hesitant, he was worried that he would break Wanwan's hand.
But Zhu Zhanji said confidently: "Zhan Yuan sit in the basket and let Wanwan pull you." ” Zhu Di nodded and said, "Just try." ” So Zhu Zhanji personally went to hook the rope to a string of pulleys, and finally handed the rope to Wanwan.
Zhu Zhan sat in the bamboo basket, feeling like a lamb waiting to be slaughtered, dazed and helpless.
Zhu Zhan is almost sixty pounds, and if he wants to use a rope to pull him up with the bamboo basket, Liang Zhong asked himself if it was okay, but it was estimated that it would be difficult.
As for Wanwan......
In front of everyone's eyes, I saw Wanwan put the rope in the palm of her hand and circled it twice, and then her body fell......
"Huh!"
The bamboo basket moved, and Zhu Zhan looked stupid inside, not believing that it was his sister pulling the rope at all.
Zhu Di's brows moved, and his hands rubbed behind his back.
"Hey!"
Wanwan got up, this time she didn't squat, but began to pull the rope one by one.
The bamboo basket gradually rose, Wanwan mastered the trick, the corners of her mouth couldn't help but curl, and she shouted: "Grandpa Huang, do you think Wanwan is amazing?"
” Zhu Di's cheeks moved slightly, and he nodded and didn't speak.
"Poof!"
Wanwan was elated, but she didn't notice that the height of the bamboo basket had ......
"Ouch!"
"Poof!"
Zhu Zhan hit the wooden pillar on the top in a daze, and as soon as the bamboo basket overturned, the person fell to the ground.
The crown princess couldn't help laughing when she saw it, but Wanwan pulled it violently, but she didn't fall down, relying on the rope.
"Hahahaha!"
Wanwan's frightened little appearance made Zhu Di laugh and laughed rarely.
Zhu Zhanji clapped his hands, and Jia Quan came over with someone carrying a large piece of iron.
"Grandpa Huang, this piece of iron weighs more than 300 catties, we can use this pulley set and pull it up alone."
In fact, there was no need to try, Zhu Di already believed it, he nodded slightly, and then squinted, but his eyes were a little scattered.
This is a real practical science, and it will not be inferior to the Mohists, no!
The Mo family is far from comparable!
This is the knowledge that can be learned by the people, if the people of the Ming Dynasty have learned mathematics and physics, what will become of the Ming Dynasty?
The iron had been hooked, and Jia Quan personally went to pull the rope.
Zhu Di glanced absentmindedly and saw the iron ore being pulled staggeringly, and then fell into deep thought.
The people should be simple, this is the judgment of the rulers for thousands of years, and it is also the unanimous demand of the mainstream society.
What would the people think if they had learned these things?
What are your plans for the future?
And most importantly, what will they think of this emperor!?
Zhu Di's eyes flashed with favor.
"Grandpa Huang, Wanwan also wants to make one!"
The iron has risen to the highest point, Jia is not red in the end, he is not panting, and he has more spare strength to look at it.
Zhu Zhanji smiled: "This is very simple, it just needs to be calculated."
The people of the Ming Dynasty learned these things, and no matter where they went in the future, they were more powerful than those aliens. ” Zhu Di's eyes moved slightly: Yes, the people of the Ming Dynasty must be more powerful than other races, otherwise after I am gone, how can Fang Xing and them fight those literati?
After fully seeing the nature of those upright gentlemen, Zhu Di was already desperate for most of the literati and civil officials.
If it goes on according to the normal trajectory, the future of the Ming Dynasty will not be different from that of the Tang and Song dynasties, but the time of destruction is different.
"What a powerful thing!"
The big eunuch couldn't help but admire after seeing Jia Quan easily put down the iron block.
Huang Yan said stupidly: "It's just some strange and obscene skills, can it still make Daming turn the world upside down?"
” Zhu Di's eyes slowed slightly, and he nodded slightly: Yes, it's just some kit kits, kit kat that will help Da Ming, why bother!
