The Economics of Prophecy

The reaction of the member who was given the ball bearing was divided into two parts. With Craig at the head, Dalgan and Pulra are flipping around as they twist the bearings. On the other hand, the extent to which Lilka and Belmini touch the bearings left on their desks with horrible fingers. The Grand Duke is giving it to the butler he refrained from beside him to have it tested. There's a difference between men and women.

The exception to the women's regiment is Alfina, staring seriously at the bearings lifted with both hands.

"Now, what does it mean to carry things? More importantly, how will you determine the power you need to carry things?"

I said as I looked over at everyone in the venue.

"Well, that weighs."

Dalgan answered.

"Correct. But it's not just the weight. It's actually a combination of weight and friction with the ground."

Vertical load x coefficient of friction, to be exact. I took out the two metals I've prepared. One is rectangular, the other is spherical. Let those two move on your desk.

"Even those of the same weight stop as soon as they have a large surface that contacts them like a rectangle, they have less point of contact with the ground like balls, and when they rotate, they keep rolling"

The sphere is in theory a surface because of its contact with the ground, actually dizzy, but smaller than a rectangle. Even more important is spinning.

"That's right. Pushing a luggage of the same weight by hand is completely different from using a luggage car."

Lilka says. Belmini snorts next door as well. In terms of the formula just now, even baggage of the same weight, if the coefficient of friction is one tenth, the force required to move it will be one tenth. It doesn't go according to calculations because of air resistance and all that, but it's something anyone knows as a everyday feeling.

Though there are a few people mixed up who you might not know.

"Yes, the wheels are there to reduce friction. But the friction that gets in the way of carrying things isn't just with the ground."

I took out the model of the carriage axle. A metal cylinder surrounds the axle. I spin the axle. The rotation stopped immediately.

"In this way, there is also friction between the axle and the bearing. Would you know if I told you that in the case of carriages, I would use horse power in vain? Moreover, in this format, the contact of the axle just beneath the bearing can cause deformation and damage. Lubricants are essential to smooth rotation and prevent breakage, but their waste is also significant."

Merchants and Craig snorted at my words. Euphilia and Alfina look in trouble. I guess you don't care about that, even though you always say you're in a carriage.

Above all, the obsession with the ride is a man's romance.

"So what about the new bearings I handed out to you, the ball bearings"

When I took out the axle of the same thickness, I gave it to the ball bearing. The men turn the axle without me having to demonstrate.

"Wow, how long do we keep going around?"

"This is amazing."

"Well, I see. This ball in the two circles is not the point. By spinning the sphere, we're not reducing the friction you just said."

"Exactly. With this bearing, the friction between the axle and the bearing can be reduced to one tenth or one hundredth."

"What controls rotation controls industry." That's what my college professor said. Automobiles and other moving objects are not the only ones. It was in modern society that the bearings were active in all of them, with rotation built into coolers, refrigerators and everything.

It is a famous anecdote that during World War II, the United States targeted Schweinfurt, where German bearing plants gather. Because if you can't make bearings, you won't be able to make most industrial products.

And inside the bearings, ball bearings, ball bearings are a groundbreaking invention. Between the inner wheel rotating with the axle and the outer wheel to be installed on the carriage, the sphere is incorporated. Doing so reduces the coefficient of friction by receiving rotation in points and rotation of the sphere itself. Moreover, the rotation of the sphere disperses the applied part of the load.

"This is amazing, I mean, it's funny"

The men are completely obsessed with mechanical toys. I don't notice the gaze I drew somewhere in the women's group and enjoy turning the bearings that stuck in my fingers.

I know how you feel, because I did it when they gave me the prototype too.

"- Wait. The balls in here and the outer circle seem to be made with a hell of a lot of precision."

Says Roston, who is calm everywhere. However, the finger is turning the outer ring.

Yes, in order to form the ball bearings, it is necessary to precisely process the metal into a spherical shape and tighten the size even further. It is a technology that has finally materialized on Earth since the industrial revolution. But......

"That's why Noel's joining us."

"I see, if you made it with alchemy, you nod this accuracy too"

"Wait, wait. If this is made of magic gold, you can buy many carriages just for materials and processing costs."

"Not so much.... I don't care how military it is. It's a boulder."

Two people with qualities in witchcraft named Fulsey and Craig noticed the problem. Military supplies have different costs, one digit at a time. The Knights' demand for transport carriages is key to this plan.

"Right. No matter how much Kenwell, you can't afford such an expensive carriage"

The next most important thing is a big merchant like Kenwell who uses a large number of carriages for transporting grain, for example. The man, who was obsessed with mechanics, also tightened his expression on the cost story.

"Well, if that's what was made of magic gold and alchemy, then you're right. It's not enough to gather all the magic gold and alchemists in the kingdom, it's her analysis that made this."

I saw the bearings' maker. Everyone's gaze was directed to Noel.

"But the prototype that you all have now is not using magic gold or alchemy. Now, Alchemist Lord Noel, please continue."

"Yes, sir"

Noel, he was upright like a wire, but he managed to answer me.

"In itself, no magic gold or magic is used. I was made……… this is what I made"

Noel placed a rectangular metal on the lecture floor that emitted a platinum glow, along with the sound of Goto. It's about a third the size of a brick. I split it into two parts. I let it open. Two rings and six sphere shapes are carved, and trenches are dug on all sides for precise upward and downward alignment.

"... I see you only made moulds out of alchemy and shaped normal metal with it"

Fulsey arrived at an understanding as soon as possible. It's called a mold. Of course, there are moulds in this world. But there are two advantages to using alchemy to make it. One is machining accuracy. It's super difficult to make precise spheres out of moulds. But it can be done by an alchemist who is a human CAD and precision machining machine.

Once moulded, it can be used by a regular blacksmith to manufacture bearings. Moreover, the mould is made of demonic conductive gold, so it is resistant to wear and heat. And that creates a second advantage.

"By the way, the prototype is soft, melting point...... made of lead that dissolves at low temperatures. Senior Plura, there are irons that are usually difficult to process."

"Oh, I'm talking about the need for strength and high temperatures to process. I just asked when I asked if I could make the mold thinner, and I don't know much about it."

"With this alchemy mold, maybe you can also process the metal."

Is it steel tap? Alchemy molds can withstand high temperatures and strong shocks. This means that the bearings created without magic are also far more durable and less fragile than the normal ones.

"Only moulds are made of alchemy, are the actual objects ordinary metals......, I see"

"- How much will it actually cost?

"Although this mould is an actual third the size. It is multiplied by more than twenty gold coins when converted into amounts. If you're actually going to make something to use for your carriage's bearings, it will cost you more than five times, probably about a hundred gold coins. Again, that's the result of Noel and Meer doing everything they can to be creative. It's more than five times what it should be."

The venue silenced on my words.

"But if you make ten bearings in this type, the cost of a per mold is ten pieces of gold. If you make a hundred pieces, one piece of gold. If you make a thousand pieces, it's one piece of silver. In fact it is exquisitely made but sturdy, lubricants are used efficiently and less damaged. Probably more than double the normal bearing."

"The same goes for life expectancy, but for the Knights, who run dozens of carriages, it's a lot less malfunctioning. If one stops, the whole worst army stops."

Craig said. Even though he is a boulder prince, he is from the scene.

"It's the same for merchants. Clearly, the more hands I get out of my throat, the more carriages I want."

"Hih!"

Prince and Jean, no. Noel was frightened by the shooting gaze of the men.

"I'm sorry it's so exciting."

Euphilia said with a glaring eye to the men who were so excited about the mech.

"Can you really make all that stuff in Bertoldo? As I was saying, Bertoldo's craftsman base is small."

"We only make it in Bertoldo. I have two points. One thing this mould can only be made with alchemy. As long as we manage the mould, we can monopolize the technology. The other is the precision of this bearing, but it's a late drawback."

"It's a flaw."

"Yes, it needs to be mounted to the carriage much more accurately than a normal bearing, as can be seen from the machining accuracy. We also need a mechanism to prevent foreign objects from getting inside. Easy to pick up vibrations, so if you don't have the idea to hold them down, you can't show the durability you had earlier."

Play far less than the slip bearings normally used. The harder it is to handle with the precision of the tools here. However, technological innovation should not be impossible if we narrow it down. Develop jigs for mounting, for example.

"Also, no matter how precise the mould, the bearings you strike out will burr, and you need to polish the ball. All the know-how I said that accumulates in Bertoldo. This is the big one."

It's just not industrialization that has a lot of factories, there's a lot of tangible intangible know-how that piles up there. We can have a competitive advantage that cannot be achieved even if we move the factory elsewhere.

In a world of slow transmission of information, and all the tricks of processing are manual. Once established, the advantage overshadows the disadvantage of the location.

"The dishes are the same to some extent, so don't get it."

"Oh, we need a lot of time to raise a confectioner."

said D'Argan and Prla.

"The next challenge is demand to encourage the accumulation of that know-how. At first, we aim to replace military carriages that can be expensive."

I saw Craig. The prince laughed invincibly.

"You want me to draw a bubble to the Knights?"

"Doesn't that suit you? The Knights who have to run around east and west in the Warcraft Flood..."

I have a story to tell you that many of the early transistors were for the military. Seeking performance over cost is a military feature. Of course, reliability is guaranteed.

"I know. But I'm not going anywhere at once."

Craig gave the answer as expected. If you buy a good fuel efficient car every time you can, it will instead be a waste of resources and costs.

"Yes. Start by replacing only around the axle of your existing carriage. Like I said, this bearing needs know-how to be mounted. Only that part leads to an intensive artisan learning. In addition, if your reputation spreads, Bertoldo will gather carriages for replacement with new bearings. The carriage naturally brings loads. It will also be possible to carry enough metal and wood from the King's Capital and Kurtheit"

I finally get to my nominal purpose.

"The trade fair is a place to create that reputation. And it's this one if technology accumulates and you can build a new carriage. Because you don't need a carriage to transport your built carriage elsewhere."

I finished the conversation. Everyone is riding out and looking at me.

"I want to see the actual carriage as soon as possible. Our Knights, who have grown in scope and numbers, urgently need to expand their transport capabilities."

Craig said.

"A little faster, I'd like to move forward with the replacement. If it is realized, everything in the business will change. The mass transportation of cereals has the greatest impact."

"If we can carry the fruit while maintaining its freshness, our confectionery will be even more attractive"

"That's right. If we can carry not only butter and cheese, but also milk, our business possibilities will expand."

"Even vegetables can be transported to Wangdu in more quantities and types."

Everyone exaggerated a little to say the transport revolution, but they seemed to understand what it meant.

"Finally, the expansion of transport capacity also removes the taga of the size of the cities that depend on the surrounding rural areas. Cities like Bertoldo can be bigger."

I saw the lord of the big city. Euphiria nodded in her hand the bearing she had received from the butler.

"Groundbreaking technologies and their exclusive methods, the training of artisans and the accumulation of know-how in the production of new carriages. Securing raw materials. Plus the buyer and the transport of what I made. Is everything included in their measures? Not only does this change the shape of Bertoldo, it changes the shape of the country..."

Everyone laughed bitterly at the words of the Grand Duke like that. It's a little odd that Noel is included in it. You seem relieved that your presentation is over, but you don't realize that you may have a name in the history of this country.

Meer understands. "I was alert to the” degree ”of getting my hands on witchcraft. I was sweet," it is the words of the secretary.
