Chapter 40: The Center of Gravity

Ge Heng thought about it for a long time, although he felt that what Sun Shao said made sense, but he still couldn't figure out how to make it simpler, he raised his head and looked at Sun Shao, who was studying his ship models, opened his mouth, but he didn't know what to say, so he had to walk behind Sun Shao, and politely arched his hand and said: "Sun Jun, forgive Heng for being stupid, and I want to ask a question or two, how can this armillary sphere be simpler." ”

"Hehehe......" Sun Shao smiled very smartly: "Sizhen, it's not that I don't want to say it, I'm just afraid that you won't be able to accept it." Don't be anxious, with your cleverness, sooner or later you will figure out the truth here. Come on, come on, you might as well introduce me to these model ships first. ”

Ge Heng frowned unwillingly, but he was embarrassed to force. In these years, academics are also wealth, people understand, but it doesn't mean that they have to tell you that Sun Shao is not too much to do, but he is a little presumptuous. He suppressed his strong curiosity, and patiently introduced these ship models to Sun Shao, hoping to satisfy Sun Shao and reveal a little avenue to him when the time came.

Sun Shao listened with relish, he touched his chin with one hand, pointed to the four-story building ship with the other, and said yearningly: "Then can this boat enter the sea?" ”

"I can't." Ge Heng categorically vetoed.

"Can't?" Sun Shao was very surprised, seeing that this ship was very magnificent, why couldn't it enter the sea.

"Sun Jun doesn't know." Ge Heng smiled confidently: "Although the building ship is tall and mighty, it can't help the wind and waves, once the wind is too strong, the building ship is very easy to capsize." Not to mention entering the sea, even if you are driving in the river, you have to avoid the wind and waves, and once the wind and waves are too high, you have to enter the port to avoid it temporarily. Speaking of which, in addition to the majesty, the building ship is actually not as good as an ordinary fighting ship, and can usually only be used as a handsome ship. ”

"Is there such a thing?" Sun Shao gasped, his eyes rolled, and he remembered what Dunwu said when he looked at Taihu Lake yesterday, could it be that the Yangtze River in this era is really much bigger than the wind and waves in later generations? Such a big ship can be blown over, how awesome it is. He was a little curious and took the model of the building boat in his hand, fiddled with it twice, and suddenly had a flash of inspiration.

"I see."

"What does Sun Jun know?" Ge Heng asked puzzled.

"I know why the ship is so prone to capsizing." Sun Shao said mysteriously.

"Why?" Ge Heng asked with wide eyes. Sun Shao was so amazing, not only did he make a new wine, but he just said that his armillary sphere was too complicated, and now he actually knew the reason why the building boat was easy to capsize, which made him a little dizzy and unnaturally held his breath.

"Do you know the center of gravity?"

"Center of gravity?" Ge Heng stared at Sun Shao blankly: "What is the center of gravity?" ”

"Uh-" Sun Shao rolled his eyes, thought for a moment, and said, "Then do you know the tumbler?" ”

"Yes, children's toys."

"Well, why doesn't the tumbler fall?"

"Isn't that easy?" Ge Heng scoffed: "The bottom of the tumbler will be filled with iron or lead, and its weight is ...... lower."

Ge Heng was halfway through speaking, but suddenly stopped, he stretched out his finger, pointed at Sun Shao, and then pointed to the model of the building ship, and stammered: "Sun Jun said that the building ship is easy to capsize because ...... Too light underneath, ...... above Too heavy? ”

"Even if it doesn't hit, it's not far away." Sun Shao held the bow of the boat in one hand and lifted the boat up, the boat shook twice in the air, and slowly came to a standstill, because the upper part was heavier, and the bottom of the boat turned a little sideways to the sky. Sun Shao drew a vertical line from the bow of the boat and said: "The center of gravity is on this line, and the center of gravity of your ship is probably in the second room, which is an unstable structure." In addition, the building ship is large, and the wind is serious, and of course it is easy to capsize. ”

He put down the boat, picked up two rectangular wooden blocks of similar size from the case, one flat and the other upright, and then said to Ge Heng: "Sizhen, you see, these two pieces of wood are very similar in size and weight, but if you use the same size of wind to blow, which one do you say is easier to fall?" ”

"Of course it's this one." Ge Heng pointed to the erected piece without thinking.

"That's it." Sun Shao picked up the pen next to him and drew a dot in the center of each of the two wooden blocks: "This is where the center of gravity is, flat, low center of gravity, vertical, high center of gravity, the higher the center of gravity, the more unstable, the lower the center of gravity, the less likely it is to overturn." ”

"Oh, I see." Ge Heng suddenly sighed: "Lao Ziyun, humility is better than high, weakness is better than strength, good is like water, water, good tends to be down, with its self-inflicted indisputability, so it can't compete with it......"

Sun Shao rolled his eyes, your grandmother's, let's talk about the center of gravity, do you need to get involved with Lao Tzu? This is common sense, and there is no need to make it so complicated. He slandered here, but Ge Heng didn't care about him, but walked around the room ecstatically, muttering something in his mouth, one moment it was a classic of sages, and the next time it was vague self-talk.

Ya is crazy. Sun Shao glanced at Ge Heng helplessly, while he was not paying attention, he quickly picked up a model of a small boat and put it into his sleeve, and then went out seriously, the sunlight outside the house was very dazzling, so that Sun Shao, who had just come out of the somewhat dim inner room, was very unaccustomed to it, he raised his sleeves to block the sun, and Dunwu, who came up, happened to see the boat model he hid in his sleeve, was taken aback, pointed to his sleeve and shouted: "Young master......"

"Shut up." Sun Shao glanced at the middle of the room with a weak heart, lowered his voice, and glared at Dunwu with a fierce look. When Dunwu saw it, he understood it, pointed at Sun Shao, and smiled with a thief.

"Grandma's, Lao Tzu told him so many truths, what's not to do with a boat." Sun Shao said confidently.

"Andβ€”" Dun Wu and Shuai Zeng invariably lengthened their voices and turned away.

"Shaft, dare to be disrespectful to Lao Tzu." Sun Shao's face was a little unbearable, he raised his legs, and imprinted a big footprint on the backs of Dunwu and Shuai Zeng, kicking the two of them forward and almost falling to Ge Xuan. Sun Shao thought of this old immortal at this time, and hurriedly shouted, "Why did you put him on the ground?" It's a cold day, what should I do if it's freezing? ”

"Isn't he a fairy, and he's still afraid of freezing?" Shuai Zeng pursed his lips.

"Fart!" Sun Shao glared, Lao Tzu still wants to keep him useful, and he was frozen to death by you, wouldn't it be a big loss. "Carry him to the bed in the house."

"Hey." When Dunwu and the others saw that he was angry, they didn't dare to fight back, and honestly carried Ge Xuan, who was soft into a puddle of mud, into the house. Sun Shao sat in the hall, touching the boat model in his sleeve, and was secretly proud, Ge Heng suddenly rushed out of the back room, grabbed his sleeve, and shouted in surprise and joy: "Sun Jun, Sun Jun, I understand, I understand." ”

"What do you understand?" Sun Shao, who was a thief, shook off Ge Heng's hand, turned his head to look at him, and pouted his lips pretending to be calm.

"I know how to keep the ship from capsizing." Ge Heng said loudly with his hands dancing.

"Uh-"

Ge Heng didn't talk nonsense with Sun Shao, rushed into the inner house, and was busy for a while, then ran out with the model of the building boat, and rushed to the courtyard with Sun Shao in his hand. There is a pool in the courtyard, and there is a well next to it, Ge Heng stuffed the model of the building boat into Sun Shao's hand, and then shook the wheel excitedly, hit more than a dozen buckets of water one after another, filled the pool to the brim, and then carefully put the model of the building boat into the water, and then jumped into the pool, jumping and jumping in the pool, stirring up a splash after a while.

The model of the building boat swayed in the water, but it never turned over.

Looking at Ge Heng, who was panting and looking crazy, Sun Shao secretly sighed, his grandmother's, this guy is too smart, he can understand it at all. The more this is the case, the more you can't let him run away, and you have to seduce him anyway.
