Momen, Qin Huaidao has always attached great importance to it.
Technology is inseparable from skilled craftsmen, and their Mo clan is the leader among the skilled craftsmen, so Qin Huaidao took them into his own hands that day!
In the three years now set, in addition to recuperating and recuperating, Qin Huaidao is going to completely open up the steam age and slowly enter the electric age!
But this requires a process, and Qin Huaidao needs to help them complete this process.
On the outskirts of Chang'an City, there is a huge, heavily guarded mansion with various furnaces.
At this moment, many big men were beating with hammers, making a banging sound and sparks flying everywhere.
"I have seen the small steam tractor made by Your Majesty... If it is copied, I believe it can achieve what Your Majesty said and travel thousands of miles a day!"
Han Qi's eyes were shining. Although he was unshaven and his body was in tatters, his eyes were scorching.
Since the discussion with His Majesty, several months have passed, with little rest, and he has been working day and night, just to develop this so-called steam engine as soon as possible.
And now, it has reached a certain scale!
"Everyone, please work harder. This gear must be made strictly according to the dimensions. There must not be too much deviation. If the deviation is too big, it will not work at all!"
Han Qi walked around and mastered every detail.
At this moment, Qin Huaidao has arrived. He has only been away from Chang'an for a few months. Seeing such a scale, he felt a little surprised in his heart.
"Yes, as expected of Mo Sect, it has made such rapid progress. It seems that this steam engine will be available in a short time."
Qin Huaidao was very happy. As long as the steam engine comes out, many things that cannot be done by manpower can be done.
Efficiency will be greatly improved!
"Your Majesty! Meet your Majesty!"
Han Qi turned around at this moment and saw Qin Huaidao approaching. He quickly bowed respectfully, his eyes full of admiration.
"Han Qi, you've been working hard recently." Qin Huaidao said with a smile.
"No! Your Majesty, please don't say that. How can you work hard for the country and the people? What's more, all this was brought about by your Majesty, and I am just a follower of Xiao Gui and Cao Sui, doing what your Majesty wants." Han Qi spoke hurriedly, not daring to take credit or feel arrogant at all.
"Don't be humble. I just gave you a mold to grow from a young age. It's not just responsible for the expansion. I know the difficulties in this!"
"Han Qi, this steam tractor will be available soon."
"How about I teach you some simple physics knowledge today?"
Although the steam engine can be invented, they do not understand a lot of physical knowledge, so naturally they cannot take advantage of the steam engine!
"Your Majesty is willing to teach me, and I am very grateful."
Han Qi's eyes immediately lit up, and he was extremely happy.
Qin Huaidao laughed, patted his shoulder, and then took out a sketch.
Pulley!
Moving pulleys and fixed pulleys, these two pieces of physical knowledge, are a major breakthrough in human development. It can be said that if no one invented these things, it would have taken a long time for human civilization to break through to what it is today.
Of course, there were simple pulleys in ancient times, but their use was probably incompatible with steam engines. What Qin Huaidao wanted to teach Han Qi today was how to maximize the use of fixed and movable pulleys.
"Build this thing!"
Qin Huaidao gave the order, and soon the craftsmen began to build it. After a while, several wheels were built.
Later, Qin Huaidao got some more ropes and fixed them.
"Han Qi, I know. You should know what this is. You have also seen its use."
"But the profound truth behind it, I guess, you probably don't know yet."
Qin Huaidao tied a pulley, fixed it, and then propped it up. After passing the rope, he put heavy objects on it.
"This is a fixed pulley. Its biggest function is to change the direction."
"You have used this thing before, from bottom to top, from left to right, but today, what I want to teach you is to use half the strength to pull the same heavy object."
"This method is the function of the moving pulley."
While saying this, Qin Huaidao found a high place, squeezed the rope on one end of the tall tree, stood on the other end of the high place, installed the movable pulley, and then also hung heavy objects below.
"Han Qi, come and try it and see how powerful this is."
After Qin Huaidao finished speaking, Han Qi was stunned for a moment, curiously climbed onto the high platform, and then pulled the rope.
The heavy object falling below weighed at least 200 kilograms, but Han Qi was surprised to find that he only used half of his strength to pull it up.
"Is this...so magical?"
Han Qi was shocked. He had only seen fixed pulleys. Now this unfixed pulley can reduce the force by half. He really didn't expect it!
"Haha, it saves effort, but there is a drawback. Do you know what it is?"
Qin Huaidao smiled and spoke, while Han Qi blinked and shook his head.
"The disadvantage is that you can't change the direction. If you want to pull something to the top, you can only pull it from the top. If so, every time we lift a heavy object, do we need to build a matching high platform? Obviously,
Unrealistic."
After Qin Huaidao said this, Han Qi actually nodded.
Yes!
If it just saves effort but can't change the direction, then it's really not of much use!
"Your Majesty, you must have a solution, right?"
Han Qi couldn't understand, and immediately looked at Qin Huaidao, with a burning look in his eyes.
"I just said that the fixed pulley can change the direction, and the movable pulley can save labor, but what if the fixed pulley and the movable pulley are combined?"
"Wouldn't it be possible to change the direction and save effort?"
After Qin Huaidao finished speaking, Han Qi's eyes lit up!
Yes, why didn't he think of it?
At this moment, Qin Huaidao had already begun to operate. One pulley was placed on top to fix it, and the other was hung on his body. After putting a rope between the two pulleys, he stood underneath.
"Han Qi, come here and pull it. It's the same heavy object. Let's feel it now."
After Qin Huaidao finished speaking, Han Qi immediately ran over and pulled down hard. The heavy object was still pulled up lightly.
This scene made Han Qi completely dumbfounded!
He had never thought that there was such a way, it was simply amazing!
"Your Majesty...this...this...can't believe it. We stand underground and can easily send things to high places, saving time and effort. This...this is amazing!"
Han Qi was extremely surprised. He never thought that such a thing would happen!
Qin Huaidao smiled, this was the result slowly accumulated by several generations of scientists, so he naturally found it incredible.
"Is it incredible? What's even more incredible is yet to come."
Qin Huaidao smiled, this is just the simplest physics knowledge, what he is going to explain to him next is the most critical and important!
