Chapter 1480 Pendulum
What Zhao Shizhen brought was a strange big thing.

To put it simply, it looks like a box car, but most of its body is made of iron. The front is a square iron frame, with the word "dry" hanging from it, and it is connected to a thick square steel block. Hang straight down as a pendulum.

Li Zhi couldn't understand what this thing was for.

The partial box board on its side is blackened with ink, and the hanging iron rod has parallel arms only touching the blackboard, and Zhao Shizhen inserted a lime stick on it.

Chen Mu said: "Changji asked craftsmen to make this. Originally, they were pursuing symmetry, beauty and decoration. After I saw it, I removed all the useless things and kept only its function."

"Function?"

"Yes, Chang Ji wants to use this thing to measure the power of muskets and even artillery."

As Chen Mu said, he lifted his blunderbuss again, and said: "The blunderbuss balls are charged according to the standard, and hit the nearest steel block. The lead shot pushes the steel block to swing back and up, and the trajectory drawn by the lime on the blackboard , is the power of the gun."

"This is not accurate." Chen Mu said and added: "Although the weight of the bullet, the amount of gunpowder and the total weight of the pendulum can be measured and weighed accurately, the force of the bullet hitting the pendulum is consumed, so It’s not entirely accurate.”

"But relatively speaking, as long as you use this tool to measure, the numbers you get will be accurate. Under different shapes, it is clear at a glance which one is strong and which one is weak."

Li Zhi was still receiving indigestible information.

It's not that the principle of this machine is difficult to understand, nor is it just the knowledge about firearms, but more importantly, why Chen Mu and Zhao Shizhen need to measure these things.

But he didn't ask, and Chen Mu naturally didn't answer, just smiled and said: "Chang Ji used this to test the cannon, and the iron rod flew away."

In fact, the Toyo Military Mansion has another method of measuring speed. It is two machines similar to a stopwatch, and one of the vulnerable parts protrudes outside.

Use the shooter to hit two machine parts fifty steps apart at the same time to obtain the value of this period of time for calculation.

The machine is not a stopwatch, but a similar clockwork gear timing tool. This production is not difficult, but the key point is that the experimental operation is difficult and expensive, and there is also a large possibility of deviation.

It was also done by Zhao Shizhen. Speaking of which, Secretary Zhao can be considered a person with extraordinary perseverance.

In the past few years, the Eastern Military Mansion has had a heavy business, whether it is Majia Port, Muye, and the Great Exploration of Central North Asia in the north, or Peru, Colombia, and Rio Guard in the south, they all need to be aggregated to the Military Mansion.

It is already difficult to sort things out.

Especially on the grasslands of North Asia, a place where the pioneers registered this year may be called Niujiao Jingouhe, because the place where the pioneers in Hexi lived was called Niujiaozhai, and the place where the pioneers in East lived was called Jingou.

Maybe Niujiaozhai in Hexi disappeared due to an accident in the second year, and they all went to Hedong to mine gold. As a result, the people who went to Niujiaozhai in the third year didn't know the name of it, so they sent people back to Dongyang Military Mansion to re-register as a certain village. .

It is also possible that due to the omissions of the scribes, multiple names of a place are used by different people in parallel, which is very complicated.

This situation may not change until the railway is built, but in the past five or ten years, the railway in East Asia may not be completed even on the eastern coast.

After all, this place is not like Great Ming Zhongzhou. It does not have such a good infrastructure, nor does it have so many manpower and industry-intensive.

At the present stage, not to mention that every county can manufacture the rails for the light railway, but it is no problem to expand to every state capital as long as they master the specifications and make them themselves with the help and supervision of Beiyang craftsmen.

This is the basis for the local railways to fully mobilize after seeing the benefits, and independently build railways in county units—they have such capabilities and desires.

Toyo, these two basic requirements are not met.

In the most vast wasteland, if you walk more than ten miles, you can’t see anything that walks upright, let alone building a railway, or even building a dirt road.

Gathering all the people from four settlements and three tribes within a radius of [-] miles, the logistics pressure alone can crush people to death.

But it is true that the number of immigrants from the mainland has increased in recent years. Thousands of boats and 10,000+ people travel between the two sides of the ocean every year.

Doing business, relocating, delivering goods, visiting relatives, retiring from the military, and even those who have not been admitted to Jinshi come to relax, and so on.

Many businessmen are registered in the mainland and in Asia, and moved their families here after receiving the real estate.

In fact, the military government does not care about the arrival of a large population. Now the counties in Asia are much stronger than before. With the assimilation of the aborigines, the government treats the common people equally, and there are already millions of people registered in the Yellow Book .

After 30 years, people here will even forget the title of indigenous people, because they have already taken root here.

In such an intense work, Zhao Shizhen can still make some gadgets for self-entertainment.

That is to say, Zhao Shizhen has no hobbies like other scribes. Since he followed Chen Mu, he has been with guns and guns all day. Although he has never been on a serious battlefield, he still has a lot of strange knowledge that can be used in military affairs.

It may be the most depressing thing for people to master strange knowledge and not be able to use it, so Zhao Shizhen will toss about it when he is free.

I used to study bird guns and made a lot of weird guns. It may be that even if I made them, the chances of being installed on a large scale are very small. Daming’s standard firearms are basically finalized, so I turned around and started researching. Tool for firearm performance.

Only occasionally, I will continue to toss individual firearms, and they are not intended to be installed on a large scale at all, such as double-barreled hand guns and large-caliber Dasanzi hand cannons. small toys.

At this meeting, Chen Mu introduced this thing named the pendulum ballistic instrument. When he walked up, he took out the pistol from his waist and pointed it at the pendulum.

His vigor was like that of a child who might have found a chance to fire a gun, which shocked Li Zhi severely.

Where has he seen such a person in the past, this is not a disagreement, it belongs to the role of a guy who pulls out a firearm when he has nothing to do.

In the smoke, the pendulum was pushed back violently, drawing a white arc on the blackboard.

Zhao Shizhen went around to look over there, then turned his head and smiled at Li Zhi, weighed his own blunderbuss and said, "This is a [-]% blunderbuss, which means that if the caliber and dose are standard, its power is that of the Taiping blunderbuss in the world. Seventy percent."

Li Zhi nodded half-understood, followed by Chen Mu pointing to the pendulum and saying, "What Chen wants is to ask Mr. to educate the students so that they become people like this machine."

"It's not pretty, it's not refined enough, the materials are simple but solid, and the most important thing is...it can solve problems."

"To be a pendulum, one must be able to solve the problem of firearm ballistics; to be a man, one must be able to solve the problem of the court."
