Daqin Engineering Corps

After listening to Shen Bing's method, Xun was angry and anxious.

"Aren't you crazy?"

"Tie twine to the wheels?"

"This is your method?!"

"I know you can improve the carriage, but it's such a muddled way!"

"What if you tie the hemp rope? Can you drive the carriage up a steep slope?"

"Could it be that you still know how to do it?"

……

Perhaps because of the double oppression from missions and orders, Xun had already lost his patience.

At this moment, upon hearing such an "unreliable" method from Shen Bing, he gave him a scolding without hesitation.

Finally added:

"If you are so free, come and help me!"

"We don't sleep for three days, maybe we can complete the task!"

Shen Bing's eyes widened immediately.

"what?"

"Three days without sleep?"

Then I became anxious and didn't care whether Xun understood or not.

"No, master! Listen to me..."

"The reason why the carriage can't go up the steep slope is because the road is slippery in rainy days!"

"Slippery road means that the friction between the ground and the wheels is reduced, so the horses can't bear it!"

"As long as I wait to increase the roughness of the wheels..."

Considering this issue from the perspective of modern physics, many people know that the increased friction of the driving wheel is conducive to climbing, so they take it for granted that the driven wheel is the opposite, but this is not the case.

If you decompose the climbing of a carriage into stationary and climbing...you must be able to stop before you can climb further.

The same is true for people pulling a hand scooter. Going uphill cannot be a balanced force. You need to stop and then push your feet hard to take a step up, and then stop and then push your feet hard to take a step forward...and so on, and finally climb up the steep slope.

The advantage of increasing the friction of the non-driving wheels is that it saves more effort during the "stopping" stage. At this time, the direction of the friction is in the same direction as the pulling force, which means that the carriage can be stopped with a small amount of force.

Conversely, if the friction between the wheels and the ground is too small, the horse must continue to exert greater force to keep the carriage from sliding down. On the basis of this force, apply greater force to go up, which is obviously more laborious.

How could Xun, who was pushing the cart hard, understand this, he was furious when he heard this, and put the cart in his hand.

"To shut up!"

"What friction, roughness!"

"Three generations of my ancestors have worked as carpenters for decades, and I have never heard of a hemp rope tied to a wheel!"

"Are you pushing or not pushing?"

Shen Bing reluctantly took Xun's place to push the cart.

But he is not reconciled.

How could this make him happy?

Knowing that you only need to tie a few hemp ropes to solve the problem, but you have to "sleep for three days" because of this?

After thinking about it, Shen Bing pushed the cart and said:

"Master, it's about my life and death, how dare I play tricks?"

"If we cooperate, we are all capital offenses, so what's the harm in letting the apprentice try?"

"Coming and going is nothing more than tying a few hemp ropes during tea time!"

"If it can be done, it will save more than a hundred people in my 'Panoner' from exhausting themselves and being questioned..."

This is Shen Bing's brilliance.

First state that trying will not waste much time.

Secondly, he pulled the gunners and other craftsmen to stand with him.

As the saying goes, when everyone gathers firewood, the flames are high, and then there is no fear of Xun's disapproval.

Sure enough, some people were moved soon.

Cang is the one who speaks.

"Yes, master!"

"It's like a brother improving a trebuchet!"

"Who would have thought that such a simple change could double the range!"

"Now that trebuchet smashed through the Great Wall of Zhao, which our army has been unable to conquer for a long time, within a few days!"

"Maybe this time..."

Another craftsman also said yes.

"What Shen Gongcheng said is true!"

"If you only need to tie the hemp rope... But it only needs a few people and a little time!"

"It's okay to try, it doesn't matter if it doesn't work!"

Others also joined in.

Xun's face softened slightly, he hesitated for a moment, then nodded and said:

"Forget it, let you try it!"

"I'd like to see what tricks you can pull off?"

As he spoke, he shook his head and waved his hand, letting others take over and replace Shen Bing and the others.

Shen Bing let out a breath, then raised his head towards a fat man, and ordered:

"Go get some twine!"

The fat man responded, and hurriedly led a few people to the warehouse.

The fat man's name is Tun.

There are two workers (corporate chiefs) under Shen Bing, one is Cang, and the other is this fat man.

During the Warring States period, many uneducated and statusless people did not have surnames.

Their names are often simple and intuitive to take a word.

For example, following this name is because he came from a carpenter family.

Woodworkers always use an ink fountain to pop out a straight line, and then follow this straight line to make.

Cang is because it was born in a Cang forest.

As for Tun...

That's because he was born as a businessman, who always hoards goods and buys low and sells high.

It is said that this businessman may be very powerful in modern times, but in the ancient times when agriculture was emphasized and business was suppressed, he was the object of everyone's contempt.

So even though this guy named Tun is a fat man, few people can think highly of him.

Because of this, this guy named Tun was a little excited when Shen Bing designated him as a worker.

Shen Bing still remembers that Tun confirmed with Shen Bing three times.

"I...me? Really...me?"

"Gongchen? I'm a...gongchen?"

"Gongcheng...isn't it a mistake?"

This guy has a bad habit of stuttering when he gets excited!

Sometimes Shen Bing was anxious for him.

But fortunately, he moves fairly neatly.

After all, he was born as a businessman, well-nourished and educated, at least able to do arithmetic.

This is also the reason why Shen Bing "follows him".

After a while, Tun and his men returned with a few bundles of hemp rope.

Shen Bing didn't say much, and ordered while doing it:

"Take a section of four feet!"

"Wrap it around a few times and tie it to the wheel!"

"Tie five pieces to each wheel!"

Everyone agreed with a "No", and then they got busy doing the same thing.

And Xun Ze sat resting on a stone beside him, as if he didn't like everyone's movements at all.

This was not a difficult task. After a while, the wheels of a carriage were tied with hemp rope in circles.

But at this moment Yang Ting turned around again, and she even recognized Shen Bing.

"You are so brave!"

"Everyone else is busy, but you are the only ones who are lazy!"

"Emotions don't pay attention to me!"

……

Shen Bing ignored her, and patted the horse to urge him to move forward.

A miracle happened. The horses dragged the carriage up the steep slope, step by step, steadily.

Startled, Xun slowly stood up.

He couldn't believe what he saw.

"Nima, what's going on?"

"Just tie a few pieces of hemp rope?"

"Can a few people push a carriage that can't get on it by themselves?"

"Who would believe this if you didn't see it with your own eyes?"

"Is this a human thing? It's simply a monster, or a fairy who knows magic!"

The other craftsmen and coachmen were also stunned, and they all stopped what they were doing and looked at the forward carriage.

Only Yang Ting didn't realize what happened, she still reprimanded angrily:

"Do you know the result of disobeying the military order?"

"I think you have lived enough!"

"Fortunately, you are still a public servant!"

……

Shen Bing asked back: "Captain, I just need to get the carriage up the steep slope, right?"

"So what?" Yang Ting asked back.

Shen Bing raised his head forward.

Yang Ting looked back in the direction indicated by Shen Bing, and then continued to curse:

"The carriage went up by itself, and it wasn't you..."

Before he finished speaking, he let out a "huh".

"The carriage goes up by itself?"

"No one pushed?"
