Seeing that Lin Xi wanted to learn so much, Mo Wushuang could only say: "Okay, okay then!"

"Look at your reluctant appearance, it's your honor to teach me, do you know?" Lin Xi was very unhappy when he saw Mo Wushuang come out, his reluctant look.

If he was in his own home, if he was willing to let others teach him, I don't know how many people would rush to teach him.

In fact, it's not that Mo Wushuang is reluctant, it's just that now Mo Wushuang is still teaching those big guys in the group, although Mo Wushuang is single-minded, but this Mo Wushuang is not strong enough to think about problems on both sides at the same time, so this is still very difficult for Mo Wushuang.

Fortunately, Lin Xi is a beginner, so give him a little popularization of the more difficult concepts and let him think about it on the side.

Mo Wushuang and Lin Xi went to the table where the two of them were eating, and gave Lin Xi a lecture.

"You said that when I fought today, I could easily defeat the opponent with relatively small force, but there is actually a basis. ”

As he spoke, Mo Wushuang drew a seesaw.

"You see this picture is a seesaw, and the seesaw is not in the middle, but in one of the thirds. So you see, if you put two pounds of stuff on the left one-third of the way from the rocker, and one pound on the right, what do you think will happen in the end?"

"What can happen here, it must be that the two catties of this side have pried up the one catty of this side. Lin Xi replied as a matter of course.

Because heavy things must have an advantage, that's how subjectively it is judged.

Mo Wushuang knew that he would make such a judgment.

"You're wrong, it's not that you're going to warp up the right side as you said, it's that both sides are going to be warped and finally it's going to be a stable state and it's level. ”

"What are you kidding, how can it be cocked on both sides, how can something heavy be pried up by something light?"

"Then you're wrong, let me ask you, why when you buy vegetables, when you weigh them, that little iron lump can weigh the vegetables?"

"Well...... Lin Xi immediately didn't know how to answer.

Yes, it seems that this is indeed the case when buying vegetables, those scales are used to weigh the food with some small pieces of iron, but in fact, those iron pieces are not as heavy as the weight of the vegetables.

"What does the scale of the grocery store have to do with what you said?"

"They are the same principle, the principle is the same, if you don't believe it, let's do a little experiment, and you can do the preparation work yourself!"

"I'll do it myself!"

Lin Xi was very straightforward, and then left the dormitory, ready to make a seesaw.

As for heavy objects, just find a few stones.

When Lin Xi left the bedroom, Mo Wushuang breathed a sigh of relief.

After a quarter of an hour, Lin Xi came back, took out all the things he had prepared, placed them on the floor of the house, and then began to do an experiment according to what Mo Wushuang said, dividing a long wooden strip he found into three equal parts, and then marking it, and finding a triangular support, marking one of the marked positions out of a small ravine for positioning, and then putting it on.

Then, Lin Xi put down two catties of weight on the left position.

When the two-pound weight was put down, the plank of the seesaw was immediately warped, and the right side was lifted high.

Then, Lin Xi put a pound of stone on the right, and the other end was warped, and the high end on the right began to fall, and finally swayed left and right in mid-air, and then stabilized in a state as Mo Wushuang said, horizontal.

"It's really going to be like this. Lin Xi couldn't quite understand the mystery.

However, he felt that it was nothing, it must have been Mo Wushuang's experiment, his first contact, and it was normal to guess wrong.

Lin Xi didn't care about these things anymore, and then sat down next to Mo Wushuang again.

"It's nothing, you must have done experiments, I haven't done experiments, and it's a matter of course to guess wrong, so you can tell me, what does this have to do with when we fight?"

"Of course it matters, there is a basis for the truth I just told you. The weight on the left multiplied by its distance is equal to the weight on the right multiplied by the distance to this fulcrum. ”

Mo Wushuang originally wanted to popularize the concept of Newton, but after thinking about it, anyway, there is no Newton in this world, so he directly uses weight instead, and this formula is also valid, so let's use it for the time being.

"Really, look at what you said, is your so-called formula universal?" Lin Xi immediately expressed some disbelief.

"Of course it's universal, if you don't believe it, can you do it again yourself? Even if you change the position of this fulcrum, the result will be the same. When you learn this principle, you can think about it in battle, in fact, what we call four or two thousand pounds, isn't it also using this principle?"

"The side with the most power, if you want to defeat him with less force, you have to make your own attack range longer, and make the opponent's attack range shorter, only in this way can you do it, and then think back to the textbook, isn't this the case?"

Lin Xi began to recall the picture in the book in his mind, and found that it seemed to be really what Mo Wushuang said, whether it was the move he practiced today, or the content behind, it seemed that the side that defeated the strong with the weak, his attack distance must be greater than that of the strong side.

"I'll try again. ”

Lin Xi didn't know if Mo Wushuang's formula could really be established, so she went to the side and continued to try, changing the distance of the fulcrum of this seesaw, and then changing the weight.

However, Lin Xi was too lazy to go outside to find another stone, so he directly took silver instead, anyway, it was the same, it was all heavy objects.

Lin Xi tried back and forth more than a dozen times, and found that it was really, no matter how it was changed, it was valid.

Only then did Lin Xi know why Mo Wushuang was so comfortable when he fought during the day, this little trick was really amazing.

As long as it is used well in the battle, it can play a great role, and when you fight with the other party, when you collide for the first time at the beginning, you can roughly judge how much power the opponent uses, unless the opponent improves the strength a lot, so it is easy to make your side slightly larger than the opponent, and you can play a perfect suppressive role.
