() Li Tianyu took Jin Yilin to his place, and looking at Li Tianyu, Jin Yilin immediately asked, "OPPA, what should we do?" ”

As always, Jin Yilin still believes in Li Tianyu, looking at Jin Yilin, this time Li Tianyu laughed very proudly, Li Tianyu may not be very clear about the so-called knowledge of South Korea, but Li Tianyu is very clear about the floating principle and state of the ship, because as a senior officer of the Celestial Empire like Li Tianyu, he needs to know a lot about ships.

While the other running men were starting to make tearing waste cartons, Li Tianyu did not build them, but began to draw a two-person ship-shaped drawing on the cardboard box.

While drawing ship-type drawings, Li Tianyu said to Jin Yilin beside him very confidently: "Shipbuilding, first of all, we have to consider the buoyancy of the ship, and the buoyancy of the ship is the action of the ship by the water pressure, the pressure on the left and right sides is balanced with each other, and the pressure at the bottom of the ship is balanced with the weight of the ship itself.

The reason why a ship floats on the water is that it is in balance with the buoyancy of gravity. The equilibrium conditions are: first, the gravity and buoyancy of the ship act on the same vertical line; The second is the displacement of the ship, that is, the weight of the discharged water is equal to the full weight of the ship, and the ship can maintain a certain floating state after loading.

There are four types of floating states of the ship: positive floating, horizontal tilting, trimming and arbitrary tilting. If the longitudinal and transverse coordinates of the center of gravity of the ship correspond to the longitudinal coordinates and transverse coordinates of the center of buoyancy, the ship is in a state of positive floating, and the bow and stern of the ship and the draft of the starboard and right sides are equal, otherwise there will be any tilt of the ship, trim or both. Generally, the design of the ship is required to maintain positive floating, or slightly tail roll. In the operation of the ship, the cargo stowage calculation should be carried out, and the loading weight and the position of the center of gravity should be controlled to obtain a good floating state."

While speaking, Li Tianyu painted while drawing, and Li Tianyu's watch made all the other running men stunned on the spot, and Jin Yilin's eyes lit up with little stars.

"Yikes!" Liu Zaishi said loudly at this time: "PD group, I protest, Tianyu is so clear about shipbuilding. Obviously professionals, how can we amateurs compare with professionals. ”

"That's it, that's it, we're protesting." Following behind, Wang Nose and Park Xiangmian also immediately protested.

Soon, the other runners protested. Because gold is so tempting, it is the entire task of all running men to destroy a master.

Watching everyone's collective protest, this made Li Tianyu himself a little crying and laughing, why did he sell his knowledge? I shouldn't be a person who likes to show off, think about it later. It turned out that it was because of Jin Yilin's adoring eyes on himself, there was no way, when a man was looked at like this by a woman with adoring eyes, he should involuntarily sell his knowledge.

However, fortunately, the PD team rejected all the protests, the reason is very simple, they did not get the news that Li Tianyu can still build ships, although the theory that Li Tianyu said just now is correct, but it is only a theory. Theory cannot succeed without practice, so all running men's protests are dismissed.

The running men had no hope for their protests, so it didn't matter if they were dismissed, they just habitually wanted to make it difficult for the strong, and soon everyone was involved in the work of the paper boat as if nothing had happened, as if there was no protest at all.

Then Liu Zaishi also came over to ask Li Tianyu's opinion, which made Li Tianyu completely understand the bottom line of variety shows.

And then the shipbuilding continued, Li Tianyu's drawings were finally drawn, and then the construction officially began, Li Tianyu and the ships built by other running men were different. Most of the boats built by other running men are because of the square shape of the cardboard box, so they built it into a square according to the pattern of the cardboard box, and Li Tianyu's boat is completely like a boat. It's almost like a boat parked on the pool.

"Wow, they made a boat, it looks like a boat." Liu Zaishi on the side saw the paper boat models of Li Tianyu and Jin Yilin, and sighed from the heart.

Why is it from the heart? Because the boat built by Liu Zaishi and Jin Guangkui is really too bad, in Jin Guangkui's words, it is the original appearance of the original refrigerator box. It's just that they glued it with duct tape.

In this way, time passed slowly, and the running men's respective boats, whether good or not, whether they were suitable or not, were all baked one by one, and in the last time, the running men also named their respective boats, and then wrote their names on their respective boats.

Then a whistle sounded, the time limit ended, looking at the boats made by the running men, Cao Xiaozhen was very satisfied and said: "Everyone is really attentive, every paper boat is very beautiful, so let's see now, their actual role, the competition is very simple, a group of races, compare the time from the www.biquge.info to the end of the Biqu Pavilion!" The fastest victory, if everyone's team can't finish it, wins the team that goes the farthest. ”

After Cao Xiaozhen explained the content of the task, the first group of contestants was on the field, the first group is Ji Seok Jin and Park Sang-mian, the name of their ship is called Chi Park TARIN, and the shape of the two-person boat is square, however, at the beginning, because they were afraid that Park Sang-mian's weight would crush the ship, so when the two were building a ship, they left a careful eye and sat in front of the boat, that is to say, Ji Seok-jin and Park Sang-mian's boat is actually composed of two boats, which are used to share the weight of the two. The big box is for Park Sang-mian to sit on, and the small box is for Ji Seok-jin to sit on.

Of course, the two of them were right, but it was the practice of that sentence that came out of the truth, and the two carried the boat off the pool, and then sat in the cabin one after the other, with the assistance of the staff around, otherwise it would be easy to destroy the boat before it started.

"OPPA, did you say their ship is OK?" Jin Yilin held his small chin and sat by the pool with Li Tianyu and said.

At this time, not only Li Tianyu and Jin Yilin, but also the other running men were also sitting in a group of people sitting by the pool and watching Park Sang-mian who was entering the paper boat.

Listening to Jin Yilin's words, Li Tianyu said with a smile: "It should be possible, it's just that their ship lacks stability, and the speed will not be very fast, and it should enter the water soon." ”

Sure enough, the one behind is the same as what Li Tianyu said, Ji Park TARIN carried the heavyweight Park Sang-mian but was still strong and did not sink, but the speed was very slow, and it entered the water at the beginning, however, what made everyone applaud was that although they took almost five minutes, they completed the whole journey, after going ashore, Park Sang-mian and Ji Seok-jin hugged each other tightly, very excited, and when they returned to the running men, Chi Seok-jin was very touched and said: "It's a very wonderful feeling, You should try it! ”
