Chapter 115 Defining Units of Weight
There is a standard unit of length, and it is not difficult to define a standard weight.

Although neither is a perfect standard unit, as long as the standard is relatively defined.

It is not difficult to define a weight standard, but the difficulty is how to use it and how to make a scale!

You don't have to think about modern electronic scales. Before the electricity is out, you don't have to think about it at all.

The only ones that can be used are the ancient Chinese steelyard and the ancient western balance scale.

Han Yuan thought about it and decided to make a pair of steelyards first.

Compared with balance scales, he is more familiar with steelyards and knows how to make them.

While making the steelyard, Won explained the principle.

"Before modern electronic scales came out, ancient people invented steelyards and balance scales 2000 years ago."

"I'm going to use the one kilogram I just defined to make a steelyard this afternoon."

"Steelyards need weights, beams and hooks, and sights need to be engraved on the beams."

"These materials are easy to get, and the weighing weight can use the previously defined standard of one kilogram."

"I can make a kilogram scale first, and then use a kilogram scale to measure grams, just make a gram scale."

A slender wooden trunk, remove the outer skin to expose the white meat inside, and clean it smooth with a plane, it is the scale beam.

Then find a fulcrum on one end of the pole, and hang a handle made of hemp rope.

There is a point to pay attention to here.

The correct fulcrum position should be that when the handle is lifted, the side of the beam that must be hooked (the scale head) must sink, and the scale tail must be lifted.

Only in this way can the '0' scale be marked when the weight is hung.

But the position of the handle is at the head of the scale, and the lengths of the two sides are inconsistent. Under normal circumstances, it is the tail of the scale that sinks.

Therefore, the hook for hanging things must provide a certain weight.

After the beam and the handle are manufactured, the Korean Won lifts the weight made of standard kilograms and hangs it on the tail of the scale, and then moves the weight a little bit until the beam is balanced.

After balancing, the place where the weight is located is the 0 scale.

Then hang something weighing one kilogram on the scale hook, move the weight back, and mark the second scale star, which is the representative of one kilogram.

Divide the distance between the zero scale star and the one kilogram scale into ten equal parts, and you can get zero tenths of a kilogram.

The principle is actually very simple, but it is still quite difficult to create a steelyard from scratch.

He was able to build a steelyard so smoothly because modern people have gone through this road once.

In addition, there are steelyards in his hometown. He has seen it with his own eyes before and knows how to use it.

The steelyard was built, and the audience in the live broadcast room were dazzled by the densely packed scale stars on it.

[Things from my hometown, I miss them so much. 】

[This is a scale?how to use? 】

[I used to buy fruit once, and an old man used it. I didn't know how to identify the weight at all, so I could only pretend to take a look. 】

[The upstairs laughed me to death, but I also had this experience. 】

[I know this thing, it's called 'Sima Scale'. 】

[? ? ? ?What scale? ????]

[It is estimated that few people in the city know each other, but those in the countryside should know how to tell the difference. 】

[No, I'm from the countryside, and I don't know how to judge the weight. 】

After the steelyard was built, the Korean Won first measured the weight of an iron ingot provided by the system.

The position of the weight finally stopped at the ten-kilogram scale star line, which meant that an iron ingot weighed ten kilograms as he had predicted before.

The tail of the scale beam is slightly raised, which means that the iron ingot hanging on the scale hook actually exceeds the weight of ten kilograms.

However, Han Yuan knew that the iron ingot should be the standard ten kilograms, and the scale he made was somewhat inaccurate.

After all, the ruler of standard length and the weight of standard weight are slightly deviated to a certain extent, and it is normal for them to be inaccurate.

Now it's just a little bit off, and he's already very satisfied.

In one afternoon, the efficiency of defining the weight unit and manufacturing a pair of steelyards is already very high.

This is thanks to the gene enhancement potion rewarded by the system.

Previously, he judged that the genetic enhancement potion could engrave experience into genes to form instincts.

But in the past few days, he discovered something new, that is, the manufacturing ability seemed to have increased a lot.

To be precise, when he got the materials to make something, he felt as if it had been made before.

And making the same thing many times will speed up the portrayal of this instinct.

The same is true of his previous fire, as if the genetic medicine awakened the instinct in the body.

Perhaps this description is more appropriate.

Han Yuan is still very interested in the genetic medicine he injected.

He has been paying attention and observing these days since the last time he lit a fire and figured out something.

This discovery made him even more interested.

He wanted to see to what extent this ability could be enhanced or evolved in the future.

The night passed quickly, and in the early morning of the next day, Won started the live broadcast every day.

The audience poured into the live broadcast room, and the number of people kept rising and falling.

On the virtual barrage, countless 'check-in' barrages emerged.

This is a trend that has become popular in his live broadcast room in recent days.

Because many viewers are at work, they will come in to check in after paying attention to his live broadcast and then exit.

Han Yuan smiled and greeted the audience in the live broadcast room, and walked towards the place where the paper was stored.

"Yesterday I made some rice paper. After a day of drying, it should be almost dry now. Let's go and have a look."

By the side of the river, a few large stones were placed on a wooden board, and a stack of papers was pressed underneath.

Remove the stones and wooden boards, and the white paper appeared in the eyes of everyone in the live broadcast room.

Han Yuan reached out and touched the top layer of paper, grinned after feeling that the paper was completely dry, and said.

"It appears that the manufactured paper is completely dry, and the quality of the paper is quite good."

"Now I just need to peel it off for him one by one."

With that said, Han Yuan also made a move.

After finding the rough edge, carefully tear the first sheet off it.

The resulting paper is thin, but flexible enough that, with a little care, it won't tear.

After a while, a thin piece of paper was completely torn from the pile of paper.

The complete white paper is about 1.5 meters long and nearly one meter wide, which amazed everyone in the live broadcast room.

【Royal rice paper! 】

[The paper made in this way...my ugly words on it will tarnish QAQ]

[Si Guoyi! 】

[Seeing the anchor making paper, I realized that there is no shortage of craftsman spirit in China, only the lack of packaging and publicity! 】

[The steps are not detailed enough, so I still can't do it when I travel to another world (dog head)]

[Grass and trees as paper, with book style! 】
