Chapter 895 Zhang Fei: A scientific geek delayed by the war
Looking at the excited Zhang Fei, Wang Xuan was really speechless. He was too lazy to pay attention to this guy who was restless, and just silently watched the test results of this horse-drawn iron cart.
The test venue was large enough, and one lap was 20 kilometers long. There was enough time for the vehicle to accelerate. Gradually, the horse ran faster and faster. Looking at the speed, it was already about 30 miles.
This speed is already very fast, but it has obviously not reached the limit speed, but the driver in front has already started to turn pale. After all, this is the first actual test. The four carriages are loaded with counterweighted iron blocks to test the load.
After that, the performance under various road conditions, but if the car rolled over at this speed... the driver felt that he was afraid that he was going to be crushed into a meat pie and die without any body parts.
The front is fine, it's all about straight-line acceleration, and the test is speed. At the back, there are curves at different angles, climbs, and downhills, which are meant to test extreme performance. As we enter the first corner, the driver
Shivering, he waved his whip to direct the horses in the direction of travel, gritting his teeth for fear of overturning.
When cornering, the entire track must have a certain inclination angle. The combined force of gravity and supporting force, which can also be said to be the component of the supporting force in the horizontal direction, is used to ensure that the vehicle can corner smoothly. If it is completely horizontal, then
It depends on the deformation of the rail to provide centripetal force. That is too dangerous and is tantamount to derailment, so it must be slightly tilted.
Huh~~ The first small curve was successfully passed. The driver did not feel the vehicle tilting. After passing the corner, he breathed a sigh of relief. The first uphill came next. When going uphill, he clearly felt that the vehicle was tilting.
After decelerating quickly, fortunately, after the speed dropped to a certain limit, the vehicle finally climbed up. The driver just breathed a sigh of relief when he suddenly felt that the speed of the vehicle suddenly accelerated, and the speed exceeded the normal limit.
"Ah!!" The coachman screamed and subconsciously started to pull the handbrake. The vehicle suddenly stopped, and even the horses pulling the coach neighed. Only then did the coachman realize that he had gone too far, and quickly released the handbrake, and the vehicle stopped.
Speed up again.
Slowly, the speed of the car has obviously exceeded that of the straight-line acceleration. Fortunately, it has not reached the limit of the horse and is still within the tolerable range.
After safely entering a straight road, the driver breathed a sigh of relief, but he thought that the curves and slopes behind would be more dangerous than the previous one, and he suddenly felt like he was about to die.
Cornering, climbing, going downhill... I passed it twice safely again, but on the third time, something went wrong after all. Some of the curves were turned too sharply.
ah!!!
Amidst the screams of the coachman, the vehicle derailed directly, and the huge momentum caused the carriage to rush out sideways. Even the four horses in front were not spared, and were carried out directly by the carriage with a neighing sound.
Seeing that the coachman was about to be crushed to death on the spot, he suddenly felt his body first lighten and then tighten, and he flew directly out, with a long scream, and flew for more than ten meters before landing safely. It took him a long time to fall to the ground in shock.
Slowing down, I breathed a long sigh of relief when I discovered that not only was I not dead, but I only had some scratches on my body. However, my whole body was completely soaked with sweat. Well, my pants were a little too wet, and some unknown liquid started to flow down.
Tick up.
"Damn it!" With a yell, Zhang Fei kicked the coachman out, "He actually peed, you are so cowardly!"
"Okay, you think I'm just as rough-skinned and fleshy as others!" Wang Xuan glared at Zhang Fei and then said: "Take the driver down, it's a good reward."
"The results of the test are obvious. Just use the last curve and slope as the maximum standard. There is no need to test the limit. Judging from the current test results, the original design plan has been achieved."
A group of people walked back while saying this. On the way, Wang Xuan said to Liu Bei: "In the past, in a war, the grain and grass needed by an army of ten thousand people required 30,000 civilians to transport it. As the duration of the war increased, the grain and grass transportation
As the distance increased, the food and grass actually used for the soldiers was less than one-tenth of the consumption, and the other 90% was wasted. In addition, a large number of civilians were recruited, which delayed food planting and caused even greater losses."
"And the civilian husbands have no money or food to take, leaving their wives, children, and children helpless, causing local unrest and other problems. Under a series of chain reactions, the cost of war is extremely high. In many cases, it takes several years or even more than ten years to accumulate enough to launch a war.
It is a foreign war, and the vitality will be severely damaged afterwards. This is why the national power will be completely depleted even though the war is victorious and a large amount of loot and land are obtained. The most obvious example is the "Wenwen" process in the early Han Dynasty.
The reason why the country was strong after the Jingzhi period, but after Emperor Wu of the Han Dynasty destroyed the Xiongnu, and harvested countless cattle, sheep and horses, the country's power declined significantly."
"But it's different after the railways. The transportation costs are so low that if you include the chain reaction, they can be reduced to one percent of the original value. There is almost no loss of national power. As long as the railway construction can keep up, we will wage wars year after year.
It will only make you richer and richer."
"The importance of railways to a country is tantamount to the lifeblood of the country. Wherever the railways go, the rule can be extremely stable. The influence it brings is not just a matter of how much food is produced. This is why I have made up my mind.
The reason for building the railway is like the area around the capital, where the dynasty's most powerful ruling power is located. The reason is because the distance is close enough, and the railway can expand this distance dozens of times."
Liu Bei seemed to understand what he heard, but he remembered one thing. Railways are the lifeblood. With railways, the dynasty will never decline!
The group arrived at the house. Zhang Fei, who had been feeling dizzy all the way, suddenly became energetic. He patted Wang Xuan's arm, pointed at something in the distance and said, "Zai Zhi, what is that thing?"
Following the direction of Zhang Fei's finger, he saw that it was a four-wheeled flatbed-like thing parked on the rails, with a seesaw-like lever on it.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! This thing is called a "human-powered rail car". It was originally designed to be used for inspection along the railway. It is driven by two people pressing the seesaw back and forth.
high speed.
"This, a human-powered rail car, is a vehicle that does not require horses and can drive automatically by simply stepping back and forth on the seesaw in the middle."
Wang Xuan explained casually. Unexpectedly, as soon as he finished speaking, Zhang Fei jumped on it enthusiastically. It was supposed to be a human-powered rail car where two people stepped on each other. He spread his thighs and stepped on it alone.
The power transmission device of this thing is extremely simple, but the simpler it is, the smaller the intermediate loss and the faster the relative speed. Before Wang Xuan could say anything, Zhang Fei, the giant monster, stepped on the human-powered rail car and 'shot' out
.
Yes, it can only be described as shooting. The speed is too fast, just like a large-displacement motorcycle that can accelerate from 100 kilometers to 100 kilometers far faster than a car.
Just a breath, and in about three or four seconds, Zhang Fei stepped on the human-powered rail car at a speed of about 40 miles and flew past the crowd, leaving only a burst of magical laughter reverberating in the air.
.
When several people chased them out of the house, the speed of the rail car must have exceeded 60 miles. Zhang Fei screamed excitedly, his legs used force again, and he stepped out of the phantom so fast. The speed of the rail car suddenly jumped to another level.
I rushed up the first ramp like flying, and then... whoosh... ah... bang...
The rail car shot directly from the ramp at high speed, and finally jumped more than ten meters before falling heavily to the ground.
That is to say, the person controlling the vehicle was Zhang Fei. If an ordinary person flew out at this speed, he would have suffered a powder fracture when he was found. However, this guy didn’t come down after flying out. He turned around and flew back directly. After landing, he rushed excitedly.
Then Wang Xuan shouted: "How about it, Zai Zhi, this is much faster than your horse-drawn cart!"
"Come on, uncle!" Wang Xuan rolled his eyes fiercely, "You think everyone is as strong as you and is stronger than an animal, and can make a rail car fly out!"
"Well, there must be very few people who are as strong as me, but..." Zhang Fei rolled his eyes and chuckled: "Can you find more people to step on at the same time? I think they are better than horses. Horses are like this."
They are just beasts after all, and they may not always be so obedient."
Wang Xuan was stunned and blinked. This world is different from normal after all. People's strength is several times greater than normal. It may not be impossible!
Especially under the premise of pursuing faster speed, after all, horses are equipped with ten horses, and more cannot be controlled, but it doesn't matter if there are more people!
Wang Xuan looked Zhang Fei up and down and said, who is pretending to be this guy today? Why did he suddenly become smart? Or maybe he is a scientist who was delayed by the war!
