Chapter 170 Do you know what friction is?？
“What exactly is Yuan Old Master studying? "Qin Feng asked aloud。
Huo Yuan rubbed his chin and replied lightly: "I heard Old Master mention by chance when he was drunk that he wanted to build a mobile city. 。”
Qin Feng's eyes widened, Howl's Moving Castle？
didn't expect, this Old Master's idea was so avant-garde！
He is indeed a man who can forge the Twelve Supreme Soldiers and build the Flying Garden.。
“But since he wants to build a mobile city, why did Old Master Yuan create a thing that looks like a cart?。
Do you have to push objects of various shapes and materials around on the ground? "Qin Feng raised doubts again。
“Old Master's original idea was to build the city on the car, just like a carriage pulling goods, through the power of Treasure Items, it affects the entire city 。
The weight of the city is definitely unusual, so when Old Master tries it, he will put cargo on the car that far exceeds the carrying capacity.。
But the result of this is often that the car will easily skid and roll over. If it encounters soft soil, the wheels will get stuck in it and become unable to move.。
Old Master suspected that it was a problem with the wheel shape, so he wanted to improve it. " Huo Yuan explained.。
Qin Feng nodded and thought to himself: "No wonder the elders have been rubbing various objects on the ground. It turns out that they are trying to find the most suitable wheel.。”
“However, Old Master tried for a long time, but found that the wheels that would not get stuck in the mud could not pull the cargo.。
Wheels that can pull cargo are easily prone to skidding and falling into the mud.。
Therefore, even though Old Master spent a lot of time on this matter, there was no progress. "Huo Yuan sighed, his tone a little regretful.。
A city that can move is simply a man's romance. As a member of the God's Workshop, he naturally yearns for such novel things.。
But who would have thought that this unprecedented research could not even take the first step?。
“Hiss~" Qin Feng scratched his cheek and looked thoughtful 。
Although Old Master is ingenious and constantly has novel ideas in his mind, the shackles of the times will inevitably limit many of Old Master’s ideas.。
“Wait, if I can help Old Master solve this initial problem, can I exchange it for him to help forge the knife as an exception? "Qin Feng's eyes were slightly bright.。
But after thinking for a moment, his face became a little ugly again.。
“This kind of thing must involve physics-related knowledge. How can I, a man who applied for liberal arts exams because I have more girls, know these things?。”
Qin Feng twitched the corner of his mouth. His physics knowledge level was still at the high school level.。
“The high school science teacher didn’t lie to me. If you learn mathematics, physics and chemistry well, you won’t be afraid of traveling all over the world.。
It's my fault that I was too young and didn't care about it.
Fortunately, since I studied Literature Saint Dao Lineage, I remember the physics knowledge in high school very clearly.。
I don’t know if this superficial knowledge is enough.。”
“Actually, I don’t need to give Old Master an answer, I just need to provide him with an idea.。
Wheels, moving, and sinking into the soil should involve knowledge about friction, pressure, etc.。
Huh? I think I have an idea. "Qin Feng raised his eyebrows, raised his steps, and approached the old man again.。
Huo Yuan stretched out his hand and was about to stop him when a heavy bag of money fell into his hand.。
When the words came to his lips, he swallowed them back。
When the senator heard the footsteps approaching, he frowned and cursed: "That little bastard" 。”
Everyone in Shen Gongfang is short of money, which is as everyone knows in Great Qian。
The little bastards use him as an excuse to sell people's information to get money. This is a private agreement.。
Old Master has naturally known this for a long time, but he has always chosen to turn a blind eye.。
It's just that he didn't expect that this kid who came today is rich and imposing, so forget it, and he's still stalking you like this.。
“Boy, if you still ask me to forge a knife, give up this intention as soon as possible and don't waste your efforts. "Old Master's attitude is still firm and his tone cannot be argued with.。
But to his surprise, the black clothed boy at this time did not mention the forging of the knife, but asked in an unfathomable mystery: "Old Master, do you know what friction is?"？”
Elder brows frowned, not sure why。
Qin Feng coughed dryly and directly memorized the knowledge from the high school physics textbook regardless of the other party's reaction.——
“Well, the so-called friction refers to two objects that are in contact and squeezing each other. When they move relative to each other or have a tendency to move relative to each other, a force is generated on the contact surface that hinders the relative movement or its trend, which is called friction. 。
Old Master, haven't you ever wondered why carriage wheels are round in shape instead of square or other shapes?？
Why can a wine glass be pushed easily on a smooth tabletop, but difficult to move on a rough floor?？
Why does the old sow wake up in the middle of the night?.”
At this point, Qin Feng stopped abruptly.。
I almost said it casually..
The elder originally planned to drink Qin Feng away, but when he heard this theory, a certain string in his mind seemed to twitch.。
He looked thoughtful, and then his eyes widened: "According to what you said, is it because circles suffer less friction than other shapes under the same conditions?？
So it’s easier for the car to move forward？”
Awesome, he was able to grasp the key points so quickly. Qin Feng was surprised, but nodded slightly, showing the look of a student that can be taught.。
“Then why can the same wine glass be easily pushed horizontally on a smooth table but not on a rough floor? "The elder quickly raised the question。
Taken the bait. Qin Feng smiled meaningfully and said lightly: "This involves the concept of friction coefficient.。”
Not far away, Huo Yuan waited for the entire group of Shen Gongfang. I originally thought that Qin Feng would be rushed back soon.。
But the development of things surprised them。
The reserved Old Master in Normal is actually having a heated discussion with the black clothed handsome Young Master.？
Even dancing with some excitement？
“what's the situation? "Gong Liang, who sensed something strange, walked aside and asked curiously。
“I don’t know. Come and have a look? "Huo Yuan glanced at。
“Walk。”
The rest of the people in Shen Gongfang looked at each other and followed the two bosses eagerly.。
Only Lan Ningshuang and three others were left in the same place.。
“What on earth are Young Brother Qin and the elders talking about? This was the first time I was so excited to see the Old Master. "Yang He looked incredulous.。
Zhang Tiannan nodded, although he did not speak, his eyes were full of curiosity。
And not long after, the group of people in the God's Workshop also experienced changes.。
They either frowned and thought, or showed joyful expressions of sudden realization.。
Breathing sounds and exclamations come and go。
Lan Ningshuang, who could no longer hold back his curiosity, and the three of them hurriedly approached
