"Huh, isn't he the protagonist~"
"My dear teacher Ren, who else can be the protagonist other than you~"
"I'll leave the romance with the mermaid to you!"
After thinking it over, Sun Hao walked towards his room refreshed.
The entire Class 9 was once again quiet in the sea breeze and moonlight, rising and falling with the waves...
......
The next day, when Ren Yan stretched and walked out of the captain's room, he saw a group of people from Class 9 gathered under the mainsail, busy with something, with many people surrounding them inside and outside.
With a hint of curiosity, Ren Yan approached the mainsail and leaned his head to look inside.
In the middle of the crowd, Xu Kai was sitting on a wooden box holding a blueprint, directing several students to fiddle with a large canvas:
"Oh, no, no, the top of this thing must be a rectangle, not a triangle!"
"Your mast is not placed correctly. It must be tilted at an angle of ten to fifteen degrees. And the distance between each mast is different. The distance gets smaller as you go up."
"Brothers, although this thing looks like a Venetian blind, it is not a Venetian blind after all. I beg you to look at the drawings and help me realize this experiment~"
"For this blueprint, I practiced Taoism again yesterday..."
"My liver feels a little shaky right now, can you please have some pity on me?"
At this moment, Xu Kai was holding a drawing and looked very haggard.
Below him, Wang Bo and a group of other idle people were busy working on the canvas while looking at Xu Kai:
"No, bro, is there really any use for you doing this?"
"This thing looks very fragile. If it encounters a strong wind like last time, it will be destroyed in no time, right?"
Hearing this, Xu Kai smiled: "Impossible~ I have already done a force analysis yesterday, this thing can definitely withstand strong winds~"
"Huh?! Are you sure you didn't do anything wrong?"
"This thing is unscientific at first glance!"
Wang Bo and others immediately came to Xu Kai, looked at the drawings carefully, and gave rebuttals.
On Xu Kai's drawing, a trapezoidal object appeared on the paper, with various parameters marked next to it.
You can tell at first glance that it is something that has been carefully researched, and not something that was done on a whim.
But even so, Wang Bo and others were still very confused when looking at this thing.
According to their first impression, this thing is definitely not a serious thing.
It seems like a product that came about spontaneously.
And it was this product that Xu Kai actually told them was a new sail?
Isn't the other party joking?
"Actually, this thing is quite scientific." When Wang Bo and his companions were about to take out the pencils they carried with them to do a force analysis, Ren Yan, who understood what they were trying to do, spoke at the right time, immediately attracting the attention of the people around them.
Wang Bo and the others also looked at Ren Yan: "Teacher Ren, are you sure?"
"It's obvious that this thing can't hold back the wind."
Ren Yan spread his hands: "I don't think Xu Kai wants to take this thing for a spin."
"Huh, no joyride?"
"Can that still be called a sail?!"
Wang Bo and the others looked back at Xu Kai again: "You don't really think so..."
"Really~" Xu Kai nodded: "This thing divides the entire sail into small grids, so it is inevitable that it cannot hold the wind."
"But it is precisely because of this that it is more sensitive to the wind. Because of its easy mobility, it can also make good use of breezes from all directions, which is what the old saying says is 'wind coming from all directions'."
"In this way, no matter how strong the wind is at sea, our ship can find a suitable direction to follow the wind force without having to fight against the natural wind force."
"Even with this kind of wind, you can achieve the effect of using only a little force to move a large object in Tai Chi."
"I only fully realized this last night. When Qingdong was surfing or sailing, didn't he always emphasize that we should not resist nature and should dance with nature?"
"We really had no choice yesterday. We simply couldn't coexist with the strong winds. We had to fight hard, but everyone saw the result."
"The 9th Class suffered considerable damage, and even the mast was hit."
"But, as long as we put on this sail, we can take advantage of all kinds of wind. As for whether we can ride the wind or not, we don't have to worry about it at all."
“We always have these breezes coming from all directions, regardless of their size.”
"The rectangular shape on the top of the sail is designed to make better use of wind energy and maximize the kinetic energy conversion of wind energy."
"In the past, the sails were set up in a triangular shape because we were afraid that the wind would be too strong and cause the wind to gather and break the limit of the sails."
"But when we don't have to think about the joyride, that worry is gone."
"Not to mention that there are basically no windless days on the sea."
"So, after changing to this sail, not only will we not lose anything, but our kinetic energy will continue to increase!"
After Xu Kai finished speaking, a hint of pride appeared in his eyes.
This thing took him nearly ten hours to create last night!
It also incorporates a lot of the experience and various ideas he accumulated during sailing.
It is simply the culmination of his current work, and Xu Kai is extremely proud of it.
After hearing this, Wang Bo and others quietly put away the pencils they had taken out, and all looked at Xu Kai as if he were a stranger.
