It seems that Guan Yu feels that Li Mengxi must understand why this is the case. Liu Bei and Zhang Fei, forget it, are not top smart.

Li Mengxi was confused. Does the speed of breaking the goal have something to do with the height of the siege spine?

He thought for a while and realized that it really mattered.

Inferring based on the extreme hypothesis, if the siege vertebra is extremely short, then when hitting the gate, it can only hit the corner of the city gate. After a long time of hard hitting, the wood of the city gate was deformed due to the impact, and even the corner of the city gate was broken.

However, the door shaft was not broken.

The city gate itself is also a lever.

When it hits the corner of the city gate, the resistance is the elastic deformation of the city gate.

Here at the city gate corner, the elastic deformation arm is long.

That is to say, the elastic deformation of the city gate offsets a lot of the kinetic energy of the siege vertebra, and the remaining kinetic energy on the gate shaft is much less, so it is difficult to destroy the gate shaft.

Therefore, if you want to break the door shaft, it is best if the ramming hammer of the siege vertebra is flush with the door shaft. In this way, the force is directly applied to the door shaft, making it easier to break the door shaft.

In reality, generally speaking, the city wall is very high, and the city gate is also very tall. The height of the city gate is much higher than the siege vertebra. It is impossible to have the siege vertebra hammer head and the city gate axis at the same height.

But even so, the higher the siege cone and the closer it is to the door axis, the greater the force exerted on the door axis, and the higher the efficiency of breaking the door by breaking the axis.

Therefore, if the siege cone wants to break through efficiently, not only must the siege cone be large, but the hammer head must be heavy, and the height must also be higher.

The height of the siege vertebra also affects the efficiency of scoring goals.

Li Mengxi was surprised and found out something more.

Li Mengxi felt that he had figured out too many things in this short time.

What made Li Mengxi even more emotional was that many problems were discovered and pointed out by Liu, Guan, and Zhang.

Liu Bei compared chopsticks to the broken steps of a siege ladder.

Liu Bei said that it is best to climb the siege ladder alone, as people in a double row can easily influence each other.

Guan Yu said that narrow ladders are light and easy to carry, and if the enemy on the city pushes the ladder, there will be less room for the enemy to draw strength.

Zhang Fei, because he attacked the city yesterday and personally led the siege team to score a goal, he used levers to figure out which point was the fastest to score a goal.

Finally, Guan Yu mentioned the issue of the height of the siege vertebra.

How many questions and ideas did these three people contribute?

This made Li Mengxi understand clearly that although he already knew that gathering the wisdom of everyone, collecting everyone's ideas and methods from Liu Guanzhang, ordinary soldiers, military doctors, carpenters, and anyone else is far more efficient than thinking alone.

There is more, but it is not enough.

Thinking about problems and collision of ideas among others also brings together the wisdom of everyone and can improve the efficiency of thinking.

It seems that from now on, I can no longer just think about the problem alone, I have to find someone to discuss it with.
