This is a simple logical reasoning, based on the previous experiments and the application of hydraulic mechanical linkages, and it is not difficult to draw conclusions. Pen, fun, pavilion www. biquge。 info

Everyone held their breath and stared motionlessly at the burning briquettes.

After a while, Jian Chen gently turned the wheel, and the piston began to move. It was a little slow at first, but it got faster and faster, and finally it couldn't stop.

"Turned! Turned! ”

I don't know who shouted loudly in the crowd, but more people stared intently at the simple little toy-like machine, stared at the connecting rod and the beauty of the machine in every movement, and listened to the whining of water in the copper furnace, and were intoxicated.

A set of ingenious self-feedback mechanism, there is no part that cannot be made now.

The piston drives the connecting rod, the connecting rod drives the runner, the other side of the runner drives the connecting rod, and the connecting rod drives the shunted air intake and exhaust device.

Every time steam comes in through the first inlet, the other side of the glass tube is just out of the air hole; When the piston moves to the other side, the driven feedback link automatically blocks the first air inlet and opens the second air inlet.

A small part of the energy from the piston is used to control the connecting rod that divides the air holes, and more energy is used to drive the runner to rotate.

This is the simplest model of a reciprocating steam engine, the cylinder is made of glass that can be seen intuitively, and those who guessed correctly that the most delicate perfection of this model can be blown by the human mouth.

It's just that although there are only two words between the model steam engine and the practical steam engine, these two words are not easy to cross.

But at this time, no one thought about the moat, and it had been completely conquered by this set of machine toys. Those who have not been in contact with hydraulic machinery are still thinking about the operation of the connecting rods, and those who have been in contact with hydraulic machinery are already thinking about what kind of connecting rods can be replaced to drive many machines.

Jian Chen looked at the reciprocating piston, extinguished the coal fire, and pulled everyone's thoughts back to reality.

This kind of amazement that does not seem to be too much as if they have seen ghosts and gods is a good thing, and it proves that the top group of people in these races use logical thinking and experience to understand that this is not driven by gods, but just a complex and perfect machine.

After a pause, there was silence for a long time.

Finally, I don't know who took the lead and applauded his hands, and then the applause was deafening, accompanied by many cheers.

Jian Chen bowed, circled around, and finally stopped the applause.

"Guys, it's just a toy, and it's still a long way from being actually usable. Today, this small machine has the strength of a rat at most. ”

But the biggest difference between this and a mouse is that it was made by us and can grow. Today it is a mouse, tomorrow it may be a rabbit, the day after tomorrow it is a cow, and the day after tomorrow may be a kun that can travel thousands of miles. ”

"Enlarge, thickened. Turn glass into iron and a small pot into a cauldron...... There's always a way to make it grow. ”

"It's a long way to grow up, so long that it can be done in a year or two years. It's close, it's far away, but we at least know another way. ”

"I saw that decades later, the whole of China was shrouded in billowing soot; I saw huge flywheels spinning and dancing in the steam. Think about it, guys. Soot, steam, loud noise, black steel, rumbling machines, what a wonderful future. ”

"What can this do? When it grows up, everything that can be done by hydraulic machinery today, it can do everything. For example, a huge hydraulic hammer becomes a steam hammer, for example, the water discharge that pulls the iron-smelting bellows becomes a piston pull, and for example, the water wheel that steps on the water becomes a water wheel that steam lifts water......"

"Workshops can be built in places that don't seem suitable today. One hired man who can fill coal can replace ten oxen. This is the meaning of the existence of our school palace, and this is the change that knowledge brings to the world. ”

"I think you've heard about my husband's talk about wheat. Imagine what our future will look like. A thousand catties of grain per mu can replace the strength of ten cows in one person...... How much grain, cotton, coal, iron, wealth will we create? ”

"Are the claims that overpopulation can kill some in this future become ridiculous? Those who think that learning is useless are hopeless in the future, and those who think that the Academy has spent a lot of money and think that some disciplines can be closed should not be out of the council? ”

"It's true, it's just a toy, but it's a toy that can grow. For all of you who are watching here today, you have learned how to cast cannons, so can you use the method of casting cannons and the scraper lathe used to scrape the barrel of the cannon to make an iron cylinder instead of glass? If you have learned hydraulic mechanical connecting rods, can you prepare new connecting rods and new machinery that conform to this reciprocating motion in advance for this kind of coal-powered machinery? ”

"Of course, there are other things to consider. For example, in a few decades, coal and iron will become the first choice for workshop construction, and the once old Yucheng will be rejuvenated because of the open-pit iron mines, where the soot will be the thickest. If I had the money and I was ready to buy a mine and a house there, I might get the price of land for my children and grandchildren even higher than in the current capital. ”

A group of people laughed out loud at the joke, but they didn't think it made sense. They believe that the seemingly easily shatterable and powerless machine in front of them can really grow, at least closer to hope than many people who spend their lives trying to change the world.

The principle has been clearly demonstrated, and the structure has basically been thought of, whether it is condensing vacuum or reciprocating mechanical feedback, it is feasible.

Many people feel that they have witnessed history, even as much as they did a long time ago, when fishing net farming was just getting started.

After listening to Jian Chen's words, many people shouted: "Light another piece of coal and let it turn for a while." ”

Jian Chen shook his head and smiled bitterly: "There are still many things I want to say, I'm afraid I won't be able to finish it in three or five days, and we are not in a hurry." I'll give this machine to the school palace, and you can watch it at any time in the future. ”

There are still three or five days left for this sentence, and the crowd suddenly exploded, looking at the boxes piled up in a row behind Jian Chen, he couldn't help but want to open those boxes now to see what else was inside.

"Ladies and gentlemen, I wonder what you thought when you saw this machine just now? You can think of anything, just say it. ”

After a moment of silence, the group of people began to babble, and Chen Jian was stunned when they heard it.

"If you want me to say, since the gas is compressed with such power, perhaps a cannon or a musket can be propelled without gunpowder. It can be compressed by air, or driven by steam, such as a cannonball pressed by the pressure of steam. ”

"The previous method of pumping water by creating a vacuum was not as good as this. If this is bigger, you can use the connecting rod to drive the water lifter, I have already thought of the structure, just like a hydraulic hammer nodding up and down, or driving the winch, it can completely lift the water higher, three zhang is not a problem. ”

"If you want to make iron, you may blow it up, and there are not necessarily fewer dead people than cast cannons."

"This thing should be able to replace horses, and maybe in the future turn horse-drawn carriages into coal-burners. At that time, there will be no grass in the post station, but coal, and after entering, the post man will directly throw coal on the car with a shovel. ”

"If that's the case, in fact, in the future it can be replaced by gunpowder. You think, if you put some gunpowder on one end of this glass tube, and the piston goes forward with a bang, and then the connecting rod is also filled with gunpowder on the opposite side, and then ignite when the piston is on the opposite side......"

…… All kinds of strange brain holes gradually flew towards the unknowable, or overexcited or quick thinking, all kinds of strange ideas more and more riveting and steaming.

Chen Jian listened to it with relish, because this was an era of brain holes, and there was no complete foundation in mechanics and materials science, and he suddenly came up with a future that seemed to be close at hand, which made these people a little fluttering.

These brain holes eventually turned into a controversy, which eventually became the protagonist of this experiment.

"If you want me to say, you can make a big iron pot on the ship, and let the steam blow the sails, so that you can sail against the wind."

"! You stand on the ship and push the mast with your hands, do you see the ship moving forward? ”

"Nonsense, because the ship is too big."

"Then you should find a small boat, and you sit on the boat and push the boat to see if the boat is going forward? It's not a big deal this time, is it? I used a wooden pole to stand on the shore and poke the boat forward. ”

The two of them were already arguing, and Jian Chen hurriedly said, "Two gentlemen, I was about to talk about this question." ”

The two of them closed their voices at the same time, and they seemed to treat Chen Jian as an arbiter of their peers, and asked, "Then you say, will it move?" ”

Jian Chen laughed and said, "It's hard to say. So, let's take it one step at a time, and I'll show you something first. ”

After speaking, Jian Chen lowered his head and picked up a stone, untied a piece of clothing belt at random, took out the skills he had learned in his previous life and made a catapult rope casually, and shook it vigorously.

The pebble made a whining sound of breaking through the air, and its crisp and neat posture attracted the applause of several young people.

"You say, 'Why does this stone fly?'

As soon as this question came out, it made people silent. Because I have never thought about this problem, and it seems that this question is too simple, and Jian Chen has scared everyone twice today, it is obvious that this question should not be as simple as they think.

After waiting for a long time, a young man muttered in a low voice, "Because...... Because you threw it so hard, you flew. ”

Jian Chen stretched out his hand and shook it, "But my hand is here, my hand is not straining when the stone is flying." ”

"But you've already used your strength."

"Then you mean that the pebbles are not supported by the strength when they are flying in the air, right? That is, after the stone flew out of my hand, it was just flying, but it wasn't because the power supported it to fly, right? ”

This question sounded a little strange, and Jian Chen said again: "Then let's put it this way, force, what is it for?" A stone flying in the air can hit someone, where does this power come from? Does a stone have power before it hits someone? If so, is this power the same as the 'power' that makes the stone fly? If so, it means that when the stone flies in the air, there is an invisible hand exerting force; If not, the power of the pebbles flying in the air is not what we think of as 'power'. ”

"Elsewhere, there is a saying in the hypothesis of particles that things always tend to remain stable in their current state, and they can be changed by heating and incineration. So does this trend towards maintaining the status quo work for these large objects such as rocks such as you and me? What is Heating Incineration? Is it a force? Is that the kind? Is it the 'force' that makes the stone fly? Or is it the 'power' that makes it hurt to hit people with stones? Are these two the same? If not, do they have anything to do with each other? ”
