It's a broken frame, after struggling for so long, it's finally done.

"Let's go, find Liu Xuande and show it to him." Li Mengxi looked at the shelf and nodded.

"Military...strategist, I still have something to do." Lu Li hesitated.

Li Mengxi glanced at Lu Li and said, "You can tell me if you have something to do." Li Mengxi was speechless.

"That's right, just poke the shelf into the ground. Is it better to have a flat bottom or a sharp bottom? I...I can't figure it out." Lu Li scratched his head and said with a smile.

What are the flat and pointed ones? Li Mengxi looked down at the torch pole in confusion.

Seeing that the bottom of the wooden pole seemed to be sharpened and pointed, Li Mengxi suddenly understood what Lu Li was referring to.

Lu Li is asking, is it better to sharpen the bottom of the wooden pole, or to saw it flat?

"Of course it's better if it's sharp," Li Mengxi replied without thinking, "You think, it's more stable when it's stuck on the ground, right?"

After listening to Li Mengxi's words, Lu Li scratched his head even more, "But when I touch it, the sharp one is always crooked when placed on the ground. It is difficult to hold up. It is not as troublesome as the flat one." Lu Li expressed his point of view.

Li Mengxi was speechless. He opened his mouth and was speechless for a moment. Li Mengxi suddenly thought, yes, if it is so sharp that it cannot stand up when placed on the ground, it will definitely fall to one side. On flat ground, it will be a wood with a flatter bottom.

The pole is more stable.

Li Mengxi was also confused about which one was better.

Then, Li Mengxi squatted on the ground with his knees bent, holding his chin with his little hand, staring at the bottom of the wooden pole, frowning slightly, and began to think deeply.

First of all, let’s put a thick wooden pole on the ground. How can we stabilize it?

Possible scoring situations.

What kind of wooden pole is the wooden pole, and what kind of ground is the ground? Is it flat? Or uneven? Is it a stone ground? Or is it a dirt ground? Is there mud on the ground in rainy days? Or is there no mud on the ground?

Also, is the wooden pole better to be pointed, flat, or pointed? If pointed is better, then how sharp is the best?

It's a simple question, but it's hard to figure it out.

To clarify this problem, which seems to be a problem of whether the wooden pole is flat or not, we need to analyze various stress conditions to truly understand it.

Li Mengxi believes that both flat poles and pointed poles have their own advantages. First, take the pointed pole as an example. A pointed wooden pole can be inserted into the ground and is not easy to slip.

As for the flat wooden pole, in a relatively flat place, because the bottom is very flat, it can be placed very stably. Even if the center of gravity is better, the wooden pole will stand on the ground by itself, just support it with your hands a little.

The two types of wooden poles naturally have their own disadvantages.

If a pointed wooden pole is placed on the ground, its center of gravity will definitely be deflected, requiring more strength to support it.

And if a flat wooden pole is placed on a smooth surface, such as ice, it is naturally not as stable as a sharp wooden pole poking into the ground.

So combined with the ground conditions, you should be able to draw a conclusion about which kind of wooden pole is easy to use - the conclusion is that neither flat bottom nor pointed bottom is easy to use, or both are easy to use.

The ground conditions are different, and the suitability of different types of wooden poles is also different.

Under normal circumstances, it is better to use a flat bottom on flat ground; when there is thick silt on the ground, or the ground is frozen, it is better to use a pointed wooden pole; if the ground is uneven, it is better to use a pointed pole.

There are many situations where the ground is flat, and there are also many situations where the ground is uneven. No matter which kind of wooden pole you use, there are situations where it is useful and there are situations where it is not so easy to use.

Thinking of this, Li Mengxi suddenly thought, can the advantages of the two wooden poles be combined? Make the wooden pole flat and pointed.

But these seem to be two contradictory conditions.

If the wooden pole is pointed, it will not be flat; if it is flat, it will not be sharp.

According to the general idea, flat and sharp are two opposite adjectives.

In reality, the bottom of the wooden pole can really be made into a flat and pointed shape.

Li Mengxi thought of a thumbtack. A thumbtack has a large nail cap, and in the middle of the cap is a very thin nail tip.

The bottom of the wooden pole can also be made like this. First, saw the bottom of the wooden pole flat, then use a chisel to cut off a layer at the bottom. When you get to the middle, leave a small spot in the middle and sharpen it, so

, the bottom of the wooden pole is pointed and flat, like an oversized thumbtack.

The weight of the wooden frame is not light. When the wooden pole is placed on the ground, the weight on it presses down on it, and the small wooden thorn at the bottom is completely nailed into the soil under the action of gravity.

In this way, it is equivalent to adding a gripping tooth to the flat-bottomed wooden pole, and the wooden pole can still stand flat on the ground. It truly perfectly combines the advantages of two different shapes of wooden poles.

Now there is only one problem left, and this problem Li Mengxi cannot solve, that is, there is only a small wooden thorn left at the bottom of the wooden pole. What is the most suitable length of this wooden thorn?

The wooden thorns have grown longer and cannot penetrate the soil completely. Even when the wooden pole is propped up, the center of gravity still tilts to one side.

If the wooden thorns are too thin and small, firstly, they will not be able to grip the ground, and secondly, the small wooden thorns will soon break or wear away.

It is inevitable that it will wear off, so it would be better if there were nails.

Unfortunately, there were no iron nails in the Han Dynasty.

Li Mengxi thought about the problem and then stood up, "Lu Li, I understand. Pointed poles and flat poles are not useful. What do you think..."

Then, Li Mengxi pulled Lu Li and muttered for a while. Li Mengxi was short, so Lu Li had to bend down, nod and bow in order to listen to Li Mengxi's words.

After listening to Li Mengxi's concise and clear speech, Lu Li's eyes widened and he looked at Li Mengxi with admiration.

The strategist is worthy of being a strategist. This idea is that the wood is made of wood that is both sharp and flat, so that it can penetrate the ground without swinging around. Such a good method can only be thought of by the strategist.

"Commander, wait a moment, I will correct it again!" Lu Li hurriedly carried the air back and went back. Lu Li didn't bother to discuss with Li Mengxi whether he should go to Liu Xuande to read it first, or wait until tomorrow to revise it.

Li Mengxi could only wait. The moon hung high in the night sky and the night was already very deep.

After waiting for about a third and a quarter of an hour, Lu Li came back carrying the wooden frame.

The wooden frame was modified according to the method mentioned by Li Mengxi. The bottom of the originally sharpened wooden pole was sawn flat, leaving a sharp wooden thorn in the middle. The wooden thorn is not long, just as long as a knuckle.

Lu Li couldn't wait to try it to see if it worked, and Li Mengxi also wanted to see the effect.

Lu Li picked up the wooden pole high, then let go, boom!

The wooden pole fell to the ground.

The ground was relatively flat, and the wooden pole that landed on the ground stopped firmly in place for two seconds, and then began to tilt to one side. Before it completely tilted, Lu Li reached out and hugged it.

It seems that the center of gravity of this wooden pole is quite good. The center of gravity of the upper wooden frame is in line with the wooden pole.

Li Mengxi approached the wooden pole and asked Lu Lixu to hold on to the frame. Li Mengxi used both hands to push the wooden pole.

Li Mengxi tried his best to grit his teeth, but he couldn't push it.

It's not because the wooden pole is too heavy, but because the wooden thorns at the bottom have penetrated into the soil and are firmly nailed into the soil, making it difficult to push.

If a wooden pole is nailed to flat ground and becomes difficult to push, then similarly in a muddy field, if the wooden spike penetrates the mud and is nailed into the solid soil under the mud, it can also remain stable in the muddy ground.
