There are many kinds of weighing things, such as rod scales with scales, bench scales that can stand on them, portable scales, spring scales, electronic scales, and so on.

However, none of these seem to be able to be made in a short period of 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 a standard weight in his hand?

Obviously, no!

So, what to do?

He thought about it for a long time, and finally came up with something that could be weighed without a standard scale. Fastest update Desktop::/

This thing is the scale.

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

What Zhao Hao wants to do is the most primitive balance, that is, to tie a rope to the middle position of a wooden stick, and then tie the other end of the rope to a fixed beam, and then hang a disc on each end of the wooden stick to put things.

In this way, as long as a weight is placed in the disc at one end, and the meat of the beast is placed on the other end, and the weight of the meat is roughly determined.

This kind of balance is very simple to make, with a divine soldier in hand, Zhao Hao brushed a few times to make a wooden shelf, and then, he used a cowhide rope to tie a wooden stick of uniform thickness under the beam of the wooden frame, and then cut two wooden plates, with a cowhide rope to hang on both ends of the wooden stick, the main body of the balance is completed.

In the meeting hall in the middle of the small courtyard of the inner valley, Zhao Hao was busy making the scales, but Ji Rushuang, Ah Yun, Ah Yue, and Ah Rou sat behind the small tables on both sides as if they were in a meeting, looking at them curiously.

What do you want to do?

I don't sleep at night, and I light an oil lamp to do something weird here.

They hadn't seen any scales, so naturally they didn't know what Zhao Hao had made.

Hanging sticks under a wooden shelf, and two wooden plates hanging at both ends of the sticks, what is the use of this thing?

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

Zhao Hao pondered for a while, then suddenly stood up and said quickly, "You wait here first." ”

With that, he swooped out of the council hall and swept swiftly in the direction of the outer valley.

When he came to the outer valley, he couldn't wait to pull out the divine soldier, rushed into the residence of the three regiments with a brush, glanced around nervously, and then waved the divine weapon, cut down a piece of bamboo, brushed, and disappeared again.

The dumplings were sleeping in a huddle at the moment, when he suddenly rushed in and woke up the three guys in one fell swoop.

What is this for?

Burst in with a knife without saying a word, grabbed a bamboo and ran!

If someone else dares to snatch their bamboo in front of them, it is strange that they don't rush up and beat people up.

However, in the hazy moonlight, they can still tell that it is Zhao Hao!

Moreover, people still carry divine weapons in their hands.

You look at me, I look at you, look at the bamboo shoots beside me, and then look at the bamboo in the corner, and finally decide to continue sleeping.

Forget it, that guy, we can't afford to mess with it, it's just a bamboo, so let's just not see it.

So, why did Zhao Hao suddenly run over and grab the bamboo?

Naturally, he was there to make weights, weights weighing a pound.

How much does a pound weigh, in the absence of a scale, it is really difficult to measure.

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

There was no wine bottle at this time, so he had to find something about the size of a wine bottle to replace it.

And the closest thing to a wine bottle is a bamboo tube.

He carried the bamboo and ran back to the inner valley council hall, and then gestured with his hand for a while, and then carefully cut off a piece of bamboo with his divine weapon.

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

He took the bamboo tube and looked at it carefully for a while, then put it next to the scale, and then looked up and said, "Ah Yun, go get water." ”

When Ah Yun 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 beside him again, brushed it, and cut off a bamboo tube that was almost the size of the bamboo tube.

Because he suddenly remembered again that a bottle of wine was a pound, however, not including the bottle.

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

The two sides of this scale can be the same weight, so he also has to cut another bamboo tube to maintain the balance on both sides, so that while adding water, add weights at the same time, and the weights are roughly about one catty. m

That's right, weights!

What do you use as a weight?

He was stunned for a moment, then suddenly got up again and ran out of the hall, flew out of the courtyard, picked up a few stones of various sizes, and then swept back quickly.

At this time, Ah Yun took a clay pot of water and placed it on the table in the middle.

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

However, he had just put the bamboo tube on the wooden plate and had not let go, when he was suddenly stunned again.

Because he suddenly realized that he couldn't let go at this time.

If he let go, the wooden plate would definitely fall down with a swish, and 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 the kind of tray balance, there is no need to worry about the tray falling rapidly, because the tray of the tray balance can move up and down the distance is so little, when one end is put on something, the tray will be pressed down by a maximum of one or two centimeters, and then it will be blocked by the base below, and will not continue to fall.

And at this time, the simple balance he made did not have anything to support the bottom, put something at one end, and put nothing at the other, and the wooden plate definitely fell down with a snap.

That's definitely not going to work.

He frowned and pondered for a while, and finally came up with a solution.

That is to use a longer rope to hang the ends of the stick on the beam as well.

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

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

With a "bang", as soon as the bamboo tube was put on, the wooden plate fell down violently, and the water in the bamboo tube also spilled out a little.

Fortunately, the wooden plate only fell about a centimeter or two, and the upper hanging rope hung the end of the wooden stick, otherwise, the bamboo tube would definitely fly out of the wooden plate, and the water in it was afraid that there would be no left.

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

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

Although this method is a bit stupid, it still works, and then, he replaced the two bamboo tubes with two clay pots, placed them on the wooden plates on both sides, poured five bamboo tubes of water into it, and added larger stones on the other hand, trying back and forth.

Soon, he found another stone of about five catties.

In the same way, it didn't take long for him to find another stone of about ten catties.

However, at this point, he seemed to be unable to try, because the wooden frame he made was too small, and the wooden stick in the middle was not thick enough, and he could not bear the weight of twenty or even fifty catties.

So, what to do?

Is it possible to make a bigger scale?

He decided, don't do it yet, and go straight to sleep!

Anyway, he already has a weight of about ten catties, and this simple balance can be used improvised.

Isn't twenty catties just two pieces of meat of ten catties!

Isn't fifty catties just five pieces of meat and ten catties of meat!
