Chapter 285 Railroad Tracks
"Understood, then do you know what's wrong with the steam car you built?"

Hearing this, Ying Changsheng looked at Gongshu Shangzao, and then asked him.

At this time, Gongshu Shangzao's face changed slightly. He carefully looked at the steam car he had built. Although it was a failed product, he could learn some experience from it. After a long time.

He pointed to the wheels under the car and said.

"This car has too many wheels!"

"Obviously four wheels can make it walk, but the minister has installed six wheels on it!"

“The more wheels there are, the greater the resistance will be!”

"Uh, who told you that?"

Ying Changsheng's expression changed slightly, and he said in embarrassment.

He said.

"Six wheels, placed there, the weight of the steam car, pressing on the six wheels, the resistance produced is roughly the same as the resistance produced by him pressing on the four wheels!"

"It's like, if you push this small wooden cart and walk on the ground, the harder you press, the harder it is to push. It doesn't matter how many wheels it has!"

"This one……"

Hearing this, Gongshu Shangzao blushed, a little embarrassed, he continued to scan the steam car in front of him, and then pointed to the ground and said.

"Could it be that the nineteenth son is saying that all this is because the road the steam car made by the minister is too rough, so the resistance increases?"

"Not bad!"

Ying Changsheng nodded.

Immediately, he pointed to the wheel of the steam car and said.

"Not only the road surface, but also the surface of the wheels is too rough..."

"But, but..."

Hearing this, Gongshu Shangzao glanced around.

Then, he said to Ying Changsheng with some embarrassment.

"Young Master Nineteen, even though that's the case, the problem is, how difficult is it to build a smooth road like a glass surface?"

"How high is the cost?"

"Yes, Young Master Nineteen, this is too difficult!"

Hearing this, the craftsmen on the side nodded and said.

Build a dirt road that runs through the top and bottom of Daqin, which is the so-called Qin Zhidao.

It has already exhausted all the strength of Daqin.

If, according to what Ying Changsheng said, to build an extremely smooth road, wouldn't that be a fool's dream?
Seeing that everyone thought so, Ying Changsheng said with a smile.

"Who said that such a road should be built?"

"Didn't I just say, resistance, resistance, resistance, important things, say it three times, don't you understand?"

"How does resistance arise?"

"It's because of friction that Gongshu was built. Look, this steam car!"

As he said that, Ying Changsheng pointed to the four steam cars, and then pointed to the wheels, the parts connected to the wheels, where the wheels were directly inserted into the axles without any connecting objects.

I saw that Ying Changsheng said to Gongshu Shangzao.

"Look here, if you replace it with a bearing, wouldn't it reduce some friction?"

"What is a bearing?"

Hearing this, Gongshu Shangzao looked dumbfounded, well, this guy has never heard of this thing.

Hearing this, Ying Changsheng was taken aback for a moment, and then he reacted.

Yes, the efficiency of this steam engine is so low, and it has nothing to do with the lack of bearings.

You know, bearings are a good thing.

It can reduce the mechanism, the friction generated when the gear rotates, and can greatly improve the efficiency of the machine.

Thinking of this, Ying Changsheng slapped his thigh fiercely and scolded himself for being stupid for thinking of this thing at this time.

He smiled slightly awkwardly, and then said.

"Bearing is a kind of machinery that can reduce friction and resistance. I just thought of it, and I will let someone make it later!"

"Really? Then hurry up and make it!"

Hearing this, Gongshu Shangzao's eyes suddenly lit up, and he said to Ying Changsheng.

Ying Changsheng said.

"This is not urgent. You were talking about roads just now. I will tell you now, why do we need to build roads?"

"We can use two smooth rails instead of roads!"

"rail?"

The moment I heard what Ying Changsheng said.

Gongshu Shangzao's face changed slightly, but he didn't react.

But Ying Changsheng said it to him.

"The surface of the iron bar is smoother than the road, right?"

"If this car is allowed to run along this smooth rail, wouldn't it mean that it can reduce a lot of friction and improve a lot of efficiency?"

"Besides, the rails are much easier than building a smooth road, right?"

"What the Nineteenth Young Master said does make some sense!"

Gongshu Shangzao nodded, and said with a frown.

"It's just that, for this rail, does it consume a little more iron?"

Well, Gongshu Shangzao thought about the consumption of iron when making rails, but all of this is not a problem in Ying Changsheng's view.

Well, iron?

What is this.

Today, Daqin's steel output is increasing steadily, and there is no shortage of such a small amount of iron at all.

It can be said that the current Great Qin Empire can easily produce countless rails without any effort at all!

"Are you afraid he won't have enough iron? The big deal is just adding a few more workshops!"

Ying Changsheng said to Gongshu Shangzao in front of him.

"It is!"

Gongshu Shangzao thought about it carefully, and it was true, he said.

"However, Young Master Nineteen, how do you turn around on this rail?"

"This is what I said before, how to solve the steering problem!"

Hearing this, Ying Changsheng laughed out loud and asked Gongshu Shangzao.

"The car itself is no longer driving on the road, but on two rails that have been prepared in advance. Under such circumstances, where is the steering device needed?"

"Just as the rails are laid, you can walk on them!"

"This this……"

Hearing this, Gongshu Shangzao was taken aback for a moment, a little unresponsive, but immediately, his eyes lit up, and in an instant, as if he saw the sun through the clouds, his mind was suddenly enlightened, and he said to Ying Changsheng who was beside him.

"Young Master Nineteen is simply a god, I never thought that there is such a way!"

Saying that, Gongshu Shangzao looked at Ying Changsheng and said.

"However, Young Master Nineteen, how did you make the bearing you mentioned earlier?"

"This is..."

Hearing this, Ying Changsheng thought about it for a while, and then made a statement to Gongshu.

"The railroad track I just imagined, the locomotive running on it, in my opinion, the locomotive is only responsible for providing traction!"

"It's like an ox pulling a cart. It's only responsible for pulling the cart, not carrying the cargo!"

"Do you understand?"

"I understand. The cars running on the rails are only responsible for providing power. If you want to pull goods in the back, you can hang the bucket on the back. What I said is no problem, right?"
