Old man Yu Ming squatted on the ground, staring closely at the huge gantry crane on the riverside not far away, his eyes shining brightly.
An extremely tough rope looped around several densely packed round wheels, and under the easy pull of two workers, the heavy objects on the cargo ship docked in the lock were lifted. The cargo was tied into a fixed cube.
, it was lifted effortlessly, and then slid along the door frame beam. The goods were lifted from the cargo ship in the lock to the shore, and placed directly on a huge flat carriage. The goods, which seemed to weigh a thousand kilograms, were
Two strong horses pulled away easily...
The well-informed old man Yu Ming has naturally seen such things as pulleys, and he even understands the principles of some levers. But this huge gantry crane designed by combining pulleys and levers so cleverly,
But it really amazed old man Yu Ming.
"Is this the kind of pulley recorded in the Mohist classic "Mo Jing"? Could it be that Fang Jun is actually a descendant of the Mohist family?"
Old man Yu Ming was shocked and whispered.
There are records about pulleys in the book "Mo Jing" compiled by Mo Zhai and his disciples.
The theory of pulleys is mentioned in detail in the book.
The pulley with a fixed central axis is called a fixed pulley, which is a deformed equal-arm lever. It does not save effort but can change the direction of the force. The pulley with the central axis moving together with the weight is called a movable pulley. It is a deformed unequal-arm lever and can save half of the force.
force, but does not change the direction of the force.
Old Yu Ming, who has read hundreds of classics of various schools of thought, naturally read this Mohist classic, so he suspected that Fang Jun was a descendant of the Mohist family who had been lost for hundreds of years...
Otherwise, how to explain Fang Jun’s unpredictable knowledge of mechanisms?
It should be noted that the core of the Mohist school is not "love all, not attack", but the art of mechanism that is unique in the world! If he were not a descendant of the Mohist family, how could Fang Jun have such profound attainments in the art of mechanism at his age?
Yu Minglei, who stood prominently behind him, remained silent.
He didn't seem to hear his uncle's doubts. His eyes were a little confused. He looked at the tall gantry crane for a while, then looked at the new sailboats that were constantly testing data in and out of the shipyard, and then looked down at the cement poured under his feet.
's impregnable dock...
Why can that small pulley easily lift goods weighing thousands of kilograms?
Why do new-style sailboats move faster in a zigzag pattern when going against the wind than when going with the wind?
Why can a pile of powder-like things become as solid as a rock after being mixed with water, sand, and pebbles?
Yu Minglei pursed his lips tightly. He felt that there was a door ajar in front of him. Some things were revealed behind the door, but they were not clearly visible. It made people crazy. He wished he could kick up the door and open it.
Kick it open and take a real look at the novel world behind the door...
If we don’t understand these things, how can we talk about the supreme way of heaven?
The old man and the young man each pondered their own thoughts and fell silent.
Brisk footsteps sounded behind me...
Yu Minglei turned his head slightly and saw Yu Mingxue walking quickly, with a cute bulging face and an unkind expression.
Yu Minglei asked casually: "What's wrong? You look very unhappy."
It was just a question. He didn't think anything big had happened.
The two brothers and sisters have always been very close, and Yu Minglei has a very good understanding of the character of arrogant girls. This girl is arrogant and willful, and she is definitely not as pink, pretty, youthful and beautiful as she looks...
"Hmph!" Yu Mingxue pouted with an angry look on his face: "It's all that Fang Jun. He looks like a dog, but in fact he is a big bastard and a big pervert! How shameless!"
Yu Minglei was shocked. This tone...could it be that Fang Jun was a wolf and took advantage of his sister?
He immediately asked anxiously: "What did that guy do?"
Yu Mingxue clenched her little fists and said angrily: "You are a talker, you are shameless, you are worse than a beast! If he hadn't run so fast, I would have punched his dog's head off with one punch!"
Yu Minglei was not surprised at all. He knew that his seemingly innocent sister was actually a violent maniac. Even if Fang Jun dared to provoke her, he would definitely hit her! What he was worried about was what Fang Jun had done.
Making my sister so angry?
The old man Yu Ming, who was "thinking about life", was also alarmed by his granddaughter. Hearing this, he asked curiously: "What on earth did Fang Jun do?"
Yu Mingxue's face turned red, a little shy, and she said in a squeaky voice: "This...that..."
After all, Fang Jun's words were too obscene. Although Yu Mingxue did not react at first and could not understand the deep meaning, but after thinking about it for a while, he naturally understood how obscene and obscene it was!
But how can a little girl repeat these words?
Old man Yu Ming was also anxious and asked urgently: "You girl, are you talking? Did that guy molest you? Oh, I told you that girls should love themselves and stay away from men, but you just didn't listen. Now,
Did you suffer a loss?"
Yu Mingxue could only say: "Actually... I didn't do anything, I just talked... it was so unpleasant..."
Yu Minglei was extremely anxious. How come this girl doesn't have the refreshing energy of the past and is dragging her feet?
"What on earth did he say? To tease you?"
Being forced by her brother and uncle, Yu Mingxue was embarrassed and annoyed. She paused and recounted what had happened, and finally said: "What did that guy say, 'How can you win people's hearts if your breasts are not huge? How can you level the world if your breasts are not flat?'"
Wow, that black boy is acting like a hooligan..."
The old man Yu Ming clicked his tongue: "'If the breasts are not big, how can we win people's hearts? If the breasts are not flat, how can we level the world?' Well, he rhymes with the rhyme and sees his heart clearly. He is worthy of being a master of poetry with great talent. This statement is really meaningful.
The charm is far-reaching..."
Yu Mingxue glared at the old man!
Is this something an uncle can say?
Which side are you from?
Old man Yu Ming knew he had made a mistake, and immediately grinned in embarrassment, making a gesture of indignation: "Huh, this guy is so brave, he dares to say teasing words, he deserves to die!"
Yu Minglei curled his lips and said: "Although Fang Jun's words are inappropriate, you can't blame him for all the mistakes. If you hadn't been aggressive and persistent in questioning, how could he have said such honest words?"
Yu Mingxue's eyes widened and she said angrily: "Yu Minglei, are you my brother?"
Seeing that the girl was about to cry, Yu Minglei said quickly and without any stance: "Yes, yes, of course! That Fang Jun is really hateful, how about I go give Xueer a beating as a brother to vent his anger?"
Yu Mingxue said angrily: "No, it's too easy for him! Go and chop off his head so that he can never say dirty words again!"
Yu Minglei sweated profusely...
Cut off someone's head with just one sentence? This girl is simply a wolf girl in sheep's clothing, so cruel! Besides, although Fang Jun is a bit vulgar, what he said is correct...
"Um...beat him a little harder, okay? Killing someone, a lot of blood will be shed, it's too cruel..." Yu Minglei had to carefully fight for Fang Jun's chance to survive.
Yu Mingxue refused, stamped his feet and said, "Are you going to kill me or not?"
Before Yu Minglei could reply, his expression suddenly became very exciting.
A voice sounded from behind Yu Mingxue: "What can't be killed? What should be killed? Chickens? Haha, Miss Yu Ming is really smart. I have recently learned a method of cooking chicken, and I want to give it to Yu Ming.
The girl is showing off her skills..."
Fang Jun led a group of naval officers to inspect the dormitory construction at the military port. Unexpectedly, as soon as he walked out of the rows of neatly arranged dormitories, he saw three people from the Yu Ming family talking, and they naturally wanted to come up and exchange a few words.
Yu Mingxue suddenly turned around and glared at the "black boy" who appeared with a pair of big bright eyes! Seeing Fang Jun's innocent look as if he had never done anything, he suddenly felt angry in his heart and grew evil, and he scolded.
: "You were running fast just now, but now you are seeking death. Suffer death! Who wants to eat your chicken..."
The petite body rushed forward, raised his delicate lotus feet, and kicked Fang Jun in the chest. Fang Jun was caught off guard, and even if he could prevent it, he couldn't prevent it. He was kicked upright, his chest felt tight, and his body was in the clouds.
It usually flies out upside down.
But now I am standing on the embankment. I flew upside down and fell directly into the water with a "plop"...
Su Dingfang, Liu Rengui and other naval officers looked at each other, then shouted, and several people jumped into the water to rescue Fang Jun. Everyone knew that this little girl looked delicate and timid, but in fact her fighting ability was amazing.
If I exerted enough force, wouldn't I be able to kick Fang Jun to death? Even if I couldn't kick him to death, he would still be choked to death...
