There are many kinds of weighing things, such as steel scales with weights, bench scales that can be stood on, case scales, spring scales, electronic scales, etc.

However, it seems that these cannot be done in a short time, because the scale basically needs to indicate the standard scale, and to indicate the standard scale, there must be a standard weight.

Does Zhao Hao have standard weights in his hand?

Obviously, no!

So, what to do?

He thought hard for a long time, and finally thought of something that could be weighed without marking the standard scale. The fastest updated PC version::/

This thing is a scale.

Of course, balances also have standard scales, such as common pallet balances with scales.

What Zhao Hao wants to do is to make the most primitive scale, that is, tie a rope to the middle of a wooden stick, then tie the other end of the rope to a fixed beam, and then hang a place for things on each end of the wooden stick.

disc.

In this way, as long as a weight-like thing is placed in the disc at one end, the meat of an exotic animal is placed on the other end, and the weight of the meat is roughly determined when the two sides are balanced.

This kind of balance is easy to make. With the magic weapon in hand, Zhao Hao made a wooden frame with a few brushes. Then, he used a cowhide rope to tie a wooden stick of even thickness under the beam of the wooden frame.

, then cut two wooden plates and hang them on both ends of the wooden stick with a cowhide rope, and the main body of the balance is completed.

In the meeting hall in the middle of the small courtyard in the inner valley, Zhao Hao was busy making a scale, while Ji Rushuang, Ayun, Ayue, and Arou were sitting cross-legged behind the small tables on both sides, watching curiously as if they were having a meeting.

What on earth does this husband want to do?

I stayed up late at night, lighting oil lamps and doing strange things here.

They had never seen any scales, so they naturally had no idea what Zhao Hao had made.

A stick is hung from the bottom of a wooden shelf, and two wooden plates are hung from both ends of the stick. What is the use of this thing?

This thing is really useless for the time being, because he has no weights in his hand, not even a standard weight of one kilogram.

Zhao Hao pondered for a while, then suddenly stood up and said quickly: "You guys wait here for a moment."

After saying that, he swooped out of the meeting hall and quickly headed towards the outer valley.

When he arrived at Waigu, he couldn't wait to draw his magic weapon, rushed into the residence of the three dumplings with a swipe, glanced around nervously, then waved the magic weapon, cut off a piece of bamboo, and swiped it,

Disappeared again.

The dumplings were hugging each other and sleeping soundly. He suddenly rushed in and woke up the three guys at once.

What is this for?

Without saying a word, he barged in with a knife, grabbed a piece of bamboo and ran away!

If someone dared to snatch their bamboo in front of them, it would be strange if they didn't rush up and beat them up.

However, in the hazy moonlight, they could still tell that it was Zhao Hao!

Moreover, he is still carrying a magic weapon in his hand.

Three dumplings, you looked at me, I looked at you, looked at the bamboo shoots beside you, then looked at the bamboo in the corner, and finally decided to continue sleeping.

Forget it, we can't afford to offend that guy, it's just a piece of bamboo, just pretend you didn't see it.

So, why did Zhao Hao suddenly come over to grab the bamboo?

Naturally, he wanted to make weights, one-pound weights.

How much does one pound weigh? It’s really hard to measure without a scale.

The only thing he could remember was that a bottle of wine weighed about one kilogram.

There was no wine bottle at the moment, so he could only find something about the same size as a wine bottle instead.

The closest thing to a wine bottle is a bamboo tube.

He carried the bamboo and ran back to the inner valley meeting hall. Then he gestured with his hands for a while, and then carefully cut off a section of the bamboo tube with his magic weapon.

The capacity of this bamboo tube should be about the same as a wine bottle.

He held the bamboo tube and looked at it carefully for a while, then placed it next to the scale, then raised his head and said: "Ayun, go get some water."

When Ayun heard this, he was stunned for a moment, then jumped up like a spring and ran straight to the kitchen.

Zhao Hao stared at the bamboo tube and thought for a while, then suddenly picked up the bamboo next to him, brushed it with a knife, and cut off another bamboo tube of about the same size.

Because he suddenly remembered that a bottle of wine is one pound, but the bottle is not included.

In other words, the wine in the bottle is a real pound. If you add the bottle, it will be far more than a pound.

The two sides of the scale had to be of equal weight, so he had to cut another bamboo tube to maintain balance on both sides. In this way, if he added water on one side and a weight on the other, the weight would be about one pound.

By the way, weights!

What to use as weights?

He was stunned for a moment, then suddenly stood up and rushed out of the meeting hall, flew outside the courtyard, picked up a few stones of different sizes, and then quickly swept them back.

At this time, Ayun took a pottery jar of water and placed it on the table in the middle.

He directly picked up the clay pot, filled a bamboo tube with water, and then picked up the bamboo tube filled with water and put it on the wooden plate of the scale.

However, just as he put the bamboo tube on the wooden plate, he was suddenly stunned again.

Because he suddenly realized that he couldn't let go just yet.

If he let go, the wooden plate would definitely fall down with a swish, the bamboo tube would definitely fly out of the wooden plate, and the water in the bamboo tube would be scattered everywhere!

This is not that kind of pallet balance. There is no need to worry about the pallet falling rapidly, because the pallet of the pallet balance can only move up and down a small distance. When something is placed on one end, the pallet will only be pressed down by a centimeter or two at most.

Then it was supported by the base below and would not continue to fall.

And the simple balance he made now has no support. If something is placed on one end and nothing is placed on the other end, the wooden plate will definitely fall down with a snap.

This is definitely not possible.

He frowned and pondered for a while, and finally thought of a solution.

That is to use a longer rope to hang both ends of the wooden stick on the beam.

In this way, even if there is something placed in the wooden plate at only one end, the wooden plate will only fall slightly by a centimeter or two, and then it will be hung by the rope above and will never fall again.

He worked for a while, until he attached hanging ropes to both sides of the wooden stick, and then carefully placed the bamboo tube filled with water in the middle of the wooden plate.

There was a "crash" sound, and as soon as the bamboo tube was put on it, the wooden plate suddenly fell down, and a little water in the bamboo tube spilled out.

Fortunately, the wooden plate only dropped about a centimeter or two and the hanging rope on it hung the end of the wooden stick. Otherwise, the bamboo tube would definitely fly out of the wooden plate, and the water inside would probably spread a little.

None left.

After placing the water-filled bamboo tube on this end, he placed another hollow bamboo tube on the wooden plate on the other side, and then placed the stones of different sizes one by one in turn.

After trying back and forth for a long time, he finally found a stone weighing about a kilogram.

Although this method was a bit clumsy, it still worked. Next, he replaced the two bamboo tubes with two clay pots, placed them on wooden plates on both sides, poured five bamboo tubes of water into them, and added more volume at the same time.

Try the big rocks back and forth.

Soon, he found another stone weighing about five kilograms.

Using the same method and not spending much time, he found another stone weighing approximately ten kilograms.

However, at this point, it seems that he can no longer try it, because the wooden frame he made is too small, and the wooden stick in the middle is not thick enough, so it cannot bear the weight of twenty kilograms or even fifty kilograms.

So, what to do?

Should we make a bigger scale?

He decided not to do anything anymore and go to bed directly!

Anyway, he already has about ten kilograms of weights, so this simple scale can be used.

Isn’t twenty kilograms just two ten kilograms of meat?
