Momen, Qin Huaidao has always attached great importance to science and technology inseparable from skilled craftsmen, and their Momen is the leader among skilled craftsmen, so Qin Huaidao will subdue them that day!

Now set for three years, in addition to recuperation, Qin Huaidao is to completely open the steam era, and slowly enter the electric age from then on!

But this requires a process, this process, Qin Huaidao needs to help them complete the suburbs of Chang'an City, a huge mansion heavily guarded, with all kinds of furnaces At this moment, many big men beat with hammers, making a thumping sound, and sparks were splashing in all directions.

"The small steam tractor made by His Majesty, I have seen it, if it is copied, I believe it can reach what His Majesty said, traveling thousands of miles a day!"

Han Qi's eyes were full of essence, although his beard was unshaven and his body was in tatters, but those eyes were scorching.

Since talking to His Majesty about that time, he has been talking about it for several months, and he has hardly rested, working day and night, just to develop this so-called steam engine as soon as possible, and now, there is also a certain scale, and that method is the role of moving pulleys. ”

Han Qi turned his head at this moment, and when he saw Zhang Leiqiong coming, he hurriedly bowed respectfully, his eyes full of admiration.

Han Qi was stunned, I had only seen a fixed pulley, and now the one with or without a fixed pulley can't add half of the power, I really didn't expect it!

"As I just said, the fixed pulley cannot change direction, and the movable pulley cannot save effort, which must be the combination of the fixed pulley and the movable pulley?

"Yes! Your Majesty is going to say that, how can you work hard for the country and the people, not to mention, everything is brought by Your Majesty, and the ministers are also Xiao Gui Cao Sui, according to Your Majesty's ideas. ”

Qin Huaidao smiled and spoke, while Zhang Lei blinked his eyes and shook his head, "Han Qi, I know, he should know what it is, and he has also seen the use of this thing."

"Han Qi, he came over and pulled it, the same heavy object, it feels like it's on at the moment."

Before Qin Huaidao finished speaking, Han Qi was stunned, climbed down the low platform with a bad surprise, and pulled the rope forward.

"Is this a way to change direction and save effort?

Han Qi thought that he understood, and immediately looked at Qin Huaidao, his eyes flashing with a scorching coldness, and the efficiency would be slightly reduced!

Before Qin Huaidao finished saying that, Han Qi really nodded, "I am willing to teach each other, and I am grateful."

Qin Huaidao laughed, patted me on the shoulder, and took out a sketch in front of him, "Everyone work hard, this gear must be built strictly according to the size, and there must not be too much deviation, if the deviation is too large, it will not be able to operate at all!" ”

Before Qin Huaidao finished speaking, Han Qi's eyes lit up!

"Yes, it is worthy of Momen, and it is so regressive, so it seems that the steam engine will be used for a long time, and it will be able to come out."

"Zhang Lei, I've worked hard recently." Qin Huaidao smiled and said.

When he said that, Qin Huaidao found a low place, squeezed the rope on one end of the low wood, stood at the other end of the low place, installed the moving pulley, and hung a heavy object above the front Qin Huaidao tied a pulley, fixed it in front of him, supported it, and the rope passed through the front and put down the heavy object.

Of course, there was no simple pulley in ancient times, but our use was probably used in conjunction with the steam engine, and what Qin Huaidao wanted to teach Han Qi today was how to play the minimum level of the moving pulley.

If it's just effortless, but there is a way to change the direction, there is really no small use for this!

Immediately, Qin Huaidao got a few more ropes and fixed them, "It's to use self-humility, I just gave him a mold, from big to small, but it's just responsible for expanding the small, I know the difficulties!" ”

The movable pulley and the fixed pulley, those two physical knowledge, but the breakthrough of human development, can not be said, if no one invents those things, I am afraid that human civilization, it will take a long time to break through to the current point.

"Isn't it incredible? Even more incredible is yet to come. ”

I never thought that there was no way, it wasn't a god!

Hehe, it's effortless, but there is no shortcoming, does he know anything? ”

That scene directly made Han Qi completely dumbfounded!

yes, how could I not have thought of that?

Han Qi hurriedly spoke, he dared to be proud of his merits and at this moment, Qin Huaidao had not finished the operation, one pulley was fixed below, and the other was hung under him, and he stood on it before using a rope between the two pulleys.

Your Majesty! Meet Your Majesty!

Han Qi was surprised, he didn't expect that there would be no such thing!

And at this moment, Qin Huaidao had already come, and he had only been away from Chang'an for a few months, and he was a little surprised to see such a scale.

"So amazing?"

"The disadvantage is not that there is a way to change direction, he wants to pull things down, so he can only pull them down, if so, every time you lift a heavy object, do you have to make a low platform to match it? This is clearly the reality. ”

"Han Qi, the steam tractor will come out in a short time."

"Han Qi, let's try it and see how that power is."

Qin Huaidao ordered to go up, and it was very slow that the craftsmen finished building, and when it was a short time, a few wheels were built, "Build this thing!" ”

Han Qi walked around, mastering every detail, "This is a fixed pulley, and the smallest function is not to change direction." ”

"But the profound truth, I guess, he should still know."

"Your Majesty, you can't help it, can you?"

Oh, yes!

Although the steam engine cannot be introduced, we know very little physics knowledge, and naturally there is a way to give full play to the minimum advantages of the steam engine!

Qin Huaidao smiled, it was the result of several generations of scientists, and I naturally thought it was incredible.

Qin Huaidao smiled, that is just the most heartfelt physics knowledge, what I picked up to explain to me is the most critical and important!

Zhang Leiqiong was very unhappy, as long as the steam engine came out, very few people could do it, and they couldn't do the heavy objects falling above, not to mention that it was not seven hundred catties, but Han Qi was surprised to find that I was able to pull it up with only half of my strength.

Pulley!

"Shall I teach him some complicated physics today?"

"They have used this object, from top to bottom, from right to left, but today, what I want to teach you is to use half the strength to pull the same weight."

"Your Majesty, you dare to doubt that you can easily send things to a low place when you stand on the ground, saving time and effort, that is amazing!

Han Qi's eyes lit up directly, and after Qin Huaidao finished speaking, Han Qi immediately ran over, and pulled it up hard at this moment, and the heavy object was still heavy and fluttering
