Brothers, the ranking of the monthly pass list has been declining!
Jazz thinks he can still save it, ask for a ticket!
…… Zhu Di and his entourage arrived at Jubao Shanwei, and Fang Xing and Zhu Zhanji were already waiting.
Zhu Di dismounted, looked at the soldiers lining up to greet him inside, and asked, "Didn't Zhanji do his homework today?"
” This question relieved the civil officials.
As long as Zhu Di still insists on Confucianism first, then any science is just a joke.
"Grandpa Huang, my grandson stopped his homework for half a day today."
Zhu Zhanji went over to accompany Zhu Di into the barracks and said: "Grandpa Huang, Zhu Gui has a grandson there, if someone wants to use what was invented here in the future, then he has to give money, otherwise the things that his grandson has invested in all these years will be gone." ” Zhu Di frowned and said: "What kind of money do you charge for things that are beneficial to the country and the people?"
” Jin Youzi and Lu Zhen in the back looked at each other, and they couldn't help but smile.
His Royal Highness the Emperor of the Ming Dynasty is really ......
There is no one before!
Zhu Zhanji smiled and said: "Grandpa Huang, if there is no return on investment, then who will research new things at such a cost in the future?"
Everyone is waiting for others to come up with it, just imitate it or go for it?
” Zhu Di said: "You are reasonable, the year before last you said that you had no money, and you borrowed a lot from me, and the Ministry of Industry also has it, right?"
” Zhu Zhanji said abruptly: "Grandpa Huang, the Ministry of Industry has taken a lot of ore, and my grandson has already made it clear at the beginning of this year, and only what you still owe is left." ” The money that his grandson owes his grandfather is an interesting thing for Zhu Di, so he softened his eyebrows and went all the way to Zhu Fang's side.
Zhu Fang changed into a new dress today, and when she saw Zhu Di, she hurriedly took the craftsmen to salute.
"There's no need to be complicated, just show me the car."
Zhu Fang was excited, and took Zhu Di to the side of the railroad track step by step, pointing and saying: "Your Majesty, look, this is the railroad track, and the horse-drawn car runs on it, which saves a lot of light and can pull a lot of goods." ” Zhu Di squatted down, knocked on the railroad tracks with his fist, touched the sleepers again, and asked, "If there is this thing at the Caoyun Wharf, many people will be redundant, right?"
” After getting up, Zhu Di saw a pile of iron at the end of the railroad tracks, and a set of pulleys erected, so he nodded and said, "This is what the dock looks like." ” Zhu Zhanji smiled: "Grandpa Huang, you better take a look first." ” "Good!"
Zhu Di got up, and Fang Xing asked Zhu Fang to drive the carriage over.
The carriage was huge, and it was actually four wheels, drawn by four horses.
This is against the rules, right?
The thought flashed, and Lu Zhen immediately smiled bitterly.
This is a truck, not a puller.
"Your Majesty, these horses are just ordinary horses, just because the car is going to load goods, they are more solid."
Zhu Di personally went over to check, and those officials also joined in the fun, and for a while, the railroad tracks and carriages were full of people.
Zhu Di is very familiar with horses, and he can distinguish them at a glance, and he mainly checked the carriage.
"Well, let's get started."
The carriage went up the railroad tracks along the small slope specially left, Zhu Fang shouted, and the craftsmen used pulleys to easily lift the iron blocks, and then put them in the carriage.
"Grandpa Huang, eighty pounds of iron."
Zhu Zhanji proudly watched the pulley group easily lift the iron block.
One, two, three......
Yang Rong was already numb, and Jin Zhong asked loudly on the side, "That Xinghebo, how many pieces?"
” Fang Xing didn't count, and said indiscriminately: "I don't know, it will be filled in the end, about a hundred yuan." ” I'll go!
Eight thousand pounds!
Zhu Di was more impressed by the wharf, when he led the army to start Jingjing, he set off from Tianjin Wei.
Tianjin Wei was called Zhigu at that time, and the goods from the south were transported here by water and transported to the north.
Thinking of the ant-dense people on the dock when the army set off, the people who were densely packed like ants were transporting the goods, Zhu Di couldn't help but show nostalgia.
If there had been such a means at that time, how many people could have been saved!
To fight a war is to burn money, and at the same time to burn people.
Regardless of ancient or modern, the army's baggage is transported step by step by manpower and animal power.
So how about this horse-drawn rail car?
When the carriage was full, a man came and sat down at the front of the carriage, flicked his whip, and the four horses moved together.
"It's moving!"
Eight thousand catties is probably just a number for civil officials, but after seeing the number of those pieces of iron, they are doubting whether these four horses can be pulled.

Two of the four horses on each side had some difficulty at first, but when the carriage moved, the movement became easier.
The coachman sat in an extra seat at the front of the carriage, with a whip in his hand, and after a shout, the carriage gradually accelerated.
"It's running!"
Yang Shiqi has ridden countless carriages and ox carts, and knows the speed of the carriage.
But this carriage pulls 8,000 catties of goods, and it can still run so easily, so fast, if there is nothing, what if it pulls people?
In the midst of this nonsense, Yang Shiqi heard someone exclaim: "I'm going to rush out!"
” The speed of the carriage is getting faster and faster, but the tracks are so long that if you rush out, you will probably have to overturn the people and horses.
Yang Rong glanced at Fang Xing, but it was light and light.
Pretend!
"Ga ......"
At this moment, there was a strange noise from the carriage in front of it, and then the carriage began to slow down.
Slowly, the carriage finally came to a halt a little in front of the end of the tracks.
"Huh!"
Liu Guan, who has better eyesight, said in surprise: "This coachman didn't get out of the car, how did the carriage stop?"
” The horse-drawn carriages and ox-carts in China have a long history, but the way they brake is very shabby.
The first way to brake is that before going downhill, the driver puts down a stick connected to the car, and pulls a rope on the stick, and the driver runs to the back of the car to pull the rope, and the stick rubs against the wheel, which is the brake.
The second is to rely on a 'brake stick' behind the car, when to slow down, the driver gets down, tilts the car back, and the stick rubs against the ground to achieve the purpose of deceleration.
But the driver didn't get out of the car just now!
When they got closer, they saw that the driver was still in the car, and their interest suddenly increased.
Most of these civil and military officials travel on horseback, but their families have to travel by car.
Over the years, there have been many incidents of frightened horses, and the coachman has no time to react, so he can only pull the reins desperately.
If you can brake, how much work can be saved!
Fang Xing watched coldly, and saw Liu Guan, Jian Yi, and Jin Youzi walking over, and then squatted down and looked at the wheels carefully, looking for the brake device.
And the others, especially Wu Xun, including Lu Zhen, all gathered around the carriage, carefully watching the structure of the carriage, and also went to inspect the railroad tracks.
"What's the point?"
The four horses were so easy that everyone thought two horses were fine.
Zhu Fang was squeezed outside, sweating profusely and said, "Your Majesty, this is ......"
"Come in and say."
Everyone dodged away, Zhu Fang came in, pointed to the rails and wheels and said, "Your Majesty, you see, the wheels are cast, with an outer edge, which coincides with the rails below, so the resistance to running is very small." ” "Resistance?"
Jin Zhong looked confused.
Zhu Fang nodded and said: "Yes, it is the resistance, the weight is pressed on the wheels, and the friction between the wheels and the ground is the resistance, and this kind of track cooperation can reduce the resistance to a minimum, once the speed starts, the inertia can be large, and the force on the horses is also small..."
Jin Zhong still looked ignorant, Zhu Fang helplessly picked up a stone and rubbed it on the ground, and said: "If there are no railroad tracks, the wheels of the carriage rub against the ground like this, creating a lot of resistance.
Rails and tracks are relatively smooth, and drag can be reduced. ” "And with four wheels, the horse doesn't have to carry weight, just pull the cart, which is not only stable, but also saves horsepower."
Looking at a group of bewildered courtiers, Zhu Di said expressionlessly: "Who taught these?"
” Zhu Fang didn't think about anything else at all, and blurted out: "This is the science taught in the academy. ” Quiescence!
The officials who were still circling around the carriage just now seemed to have been immobilized and remained motionless.
This invention that saves time, manpower, and expense is what science is in?
Zhu Zhanji said: "Grandpa Huang, this truth is in the physics book, as long as you study it seriously and work hard, most people can understand it, and maybe someone will be able to invent something more powerful one day." ” Is everyone Yao Shun?
The ministers' eyes were complicated, and their hearts were entangled.
Zhu Di said lightly: "Let's take a look and see what else this car can do." ” As a result, the uncomfortable ministers began to 'study' unwillingly and reluctantly.
