When Zhu Di and his party arrived at Jubao Mountain Guard, Fang Xing and Zhu Zhanji were already waiting.
Zhu Di dismounted, looked at the soldiers arrayed inside, and asked, "Does Zhanji have no homework today?"
This question made the civil servants breathe a sigh of relief.
As long as Zhu Di still insists on putting Confucianism first, then any science will be just a joke.
"Grandpa Huang, my grandson stopped doing homework for half a day today."
Zhu Zhanji went over to accompany Zhu Di into the military camp and said, "Grandpa Huang, does Zhu Gui have a grandson's role? If someone wants to use the things invented here in the future, they have to give money, otherwise the grandson has invested in it all these years." Everything is gone."
Zhu Di frowned and said, "How much do you charge for things that are beneficial to the country and the people?"
Jin Youzi and Lu Zhen behind them looked at each other and couldn't help but smile.
¡°His Royal Highness, the great grandson of the Ming Emperor, actually cares about money like a businessman. It is reallyunprecedented!
Zhu Zhanji smiled and said: "Grandpa Huang, if there is no return on investment, then who will study new things regardless of the cost in the future? Why don't we just wait for others to come up with it and just imitate it or do it?"
Zhu Di said: "You are right. You said you had no money the year before last, so you borrowed a lot from me. Is there some from the Ministry of Industry?"
Zhu Zhanji said in surprise: "Grandpa Huang, the Ministry of Industry just took a lot of ore, and my grandson has already paid it back at the beginning of this year, and you are the only one who still owes it."
The money that his grandson owed his grandfather was an interesting thing for Zhu Di, so he softened his eyebrows and went all the way to Zhu Fang.
Zhu Fang changed into new clothes today. When she saw Zhu Di, she hurriedly led the craftsmen to salute.
¡°No need to be complicated, just show me that car quickly.¡±
Zhu Fang was so excited that she turned around and took Zhu Di to the edge of the railway track. She pointed and said: "Your Majesty, look, this is the railway track. Horses pull carts on it. It saves a lot of time and can haul a lot more goods." .¡±
Zhu Di squatted down, knocked on the rails with his fist, touched the sleepers, and asked: "If there is this thing at the water transport terminal, many people will be redundant, right?"
After getting up, Zhu Di saw a pile of iron blocks at the end of the rails and a pulley set up, so he nodded and said, "This is what the dock looks like."
Zhu Zhanji smiled and said, "Grandpa Huang, you'd better take a look first."
"good!"
Zhu Di stood up, and Fang Xing asked Zhu Fang to drive the carriage over.
The carriage was very big, and it actually had four wheels and was pulled by four horses.
Is this against the rules?
The thought flashed past, and Lu Zhen smiled bitterly.
This is a truck, not for pulling people.
"Your Majesty, these are just ordinary draft horses. They are built to be stronger because the cart has to carry goods."
Zhu Di went over to inspect it personally, and the officials also joined in the fun. For a while, the tracks and carriages were full of people.
Zhu Di was very familiar with horses and could tell them apart at a glance. He mainly checked the carriages.
"Well, let's get started."
The carriage climbed onto the railway track along the specially left small slope. Zhu Fang shouted, and the craftsmen easily lifted the iron block with a pulley and put it in the carriage.
"Grandpa Huang, an iron block weighs eighty kilograms."
Zhu Zhanji watched proudly as the pulley lifted the iron block easily.
One piece, two pieces, three pieces
Yang Rong was already numb, and Jin Zhong asked loudly from the side: "How much does Uncle Xinghe cost?"
Fang Xing didn¡¯t count, so he said casually: ¡°I don¡¯t know, it will cost about a hundred yuan to fill it up in the end.¡±
I go! Eight thousand catties!
Zhu Di had a deep impression of the dock. When he led the army to start the Jingnan campaign, he set out from Tianjin Wei.
Tianjin Wei was called Zhigu at that time, and goods from the south were transported here by water to the north.
Recalling that when the army set off, Zhu Di couldn't help but look nostalgic at the docks where civilians were transporting cargo and baggage as dense as ants.
¡°If such a method had been available at that time, how many civilians could have been saved!
"War is a waste of money, and it is also a waste of people.
Regardless of ancient and modern times, the army's baggage relies on manpower and animal power to transport it step by step.
SoHow about a horse-drawn rail car?
When the carriage was full, a man came and sat in front of the carriage. With a whip, the four draft horses moved together.
"Move, move!"
Eight thousand catties is probably just a number to civil servants, but after seeing the number of iron blocks, they all doubted whether the four horses could pull it.
With four horses, two on each side, it was a bit difficult at first, but after the carriage started moving, the movement became easier.
The coachman sat on a seat added to the front of the car, holding a whip in his hand. After shouting, the carriage gradually accelerated.
"Let's run!"
Yang Shiqi has ridden in horse-drawn carriages and ox-carts countless times and knows the speed of horse-drawn carriages.
¡°But this carriage pulls eight thousand kilograms of cargo, and it can still run so easily and fast, as if it had nothing. What if it was pulling people?
In the midst of his random thoughts, Yang Shiqi heard someone exclaim: "I'm about to rush out!"
The carriage is getting faster and faster, but the track is only so long. If it rushes out, it is estimated that both the people and the horse will capsize.
Yang Rong glanced at Fang Xing, but his expression was calm.
Pretending to be mysterious!
"Gah"
At this time, there was a strange noise from the carriage in front, and then the carriage began to slow down.
Slowly, the carriage finally stopped a little before the end of the track.
"Huh!"
Liu Guan, who has better eyesight, said in surprise: "The driver didn't even get out of the car, how did the carriage stop?"
Horse-drawn carriages and ox-carts in China have a long history, but the braking method is very shabby.
The first way to brake is that before going downhill, the driver puts down a stick connected to the car, with a rope attached to the stick. The driver runs to the back of the car and pulls the rope, and the stick rubs against the wheels. This is the brake.
The second type relies entirely on a "brake stick" at the back of the car. When it is time to slow down, the driver gets down and tilts the car backwards, and the stick rubs against the ground to achieve the purpose of slowing down.
But the coachman didn¡¯t get out of the car just now!
After getting closer, everyone saw that the coachman was still in the car, and their interest suddenly increased.
Most of these civil and military officials travel by horseback, but their families have to travel by car.
In recent years, there have been frequent incidents of spooking horses. The coachman had no time to react and could only pull the reins desperately.
If you can brake, how much trouble can be saved!
Fang Xing watched with cold eyes and saw Liu Guan, Jian Yi, and Jin Youzi walking over. Then he squatted down and looked at the wheels carefully, looking for the braking device.
" Others, especially Wu Xun, including Lu Zhen, all gathered around the carriage, carefully looking at the structure of the carriage, and some went to check the rails.
"What's the point of this?"
The four horses pulled it so easily that everyone thought two horses would be fine.
Zhu Fang was squeezed outside, sweating profusely and said: "Your Majesty, this is"
"Come in and tell me."
Everyone moved out of the way, Zhu Fang came in, pointed to the rails and wheels and said: "Your Majesty, you see, the wheels are cast and have outer edges that coincide with the rails below. This way, the resistance to running is very small."
"Resistance?"
Jin Zhong looked confused.
Zhu Fang nodded and said: "Yes, it is resistance. The weight is pressed on the wheel, and the friction between the wheel and the ground is resistance. This kind of track cooperation can reduce the resistance to a minimum. Once it starts to speed up, the inertia will be great, and the horse will suffer The strength is also small"
Jin Zhong still looked confused, and Zhu Fang helplessly picked up a stone and rubbed it on the ground, saying: "If there were no rails, the wheels of the carriage would just rub against the ground, creating a lot of resistance. And the rails and tracks are relatively smooth, so the resistance would be Can be reduced.¡±
"And with four wheels, the horses don't have to bear weight and can only pull the cart. This is not only stable, but also saves horsepower."
Looking at a group of confused ministers, 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.¡±
Silence!
The officials who were milling around the carriage just now seemed to have been immobilized and remained motionless.
??This invention that can save time, manpower and cost is something in science?
Zhu Zhanji said: "Grandpa Huang, this principle is in the physics book. As long as you study seriously and practice diligently, most people can understand it. Who knows who will invent something more powerful one day."
Is everyone a follower of Yao and Shun?
The ministers¡¯ eyes were complicated and their hearts were tangled.
Zhu Di said calmly: "Everyone, let's take a look and see what else this car can do."
So, the officials, who felt uncomfortable in their hearts, began to 'research' unwillingly. (Remember the website address: www.hlnovel.com)His eyes were complicated and his heart was tangled.
