Steel, Guns and the Industrial Party Across the World Chapter 286

Joss was lying on the grass, shaking a piece of dogtail grass in his mouth, and there were a few soldiers like him beside him, lazily basking in the sun.

The sunlight was a bit dazzling, and Joss squinted his eyes, watching the figures in the distance hurrying back and forth.

"Hey! Tom, how do you think about it? It's just a picture. As for such a laborious..."

"Jose!"

Before Joss could finish speaking, there was a loud roar in the distance.

Hearing this sound, the bodies of several people jumped up from the ground like a clockwork, and then stood still.

"Let me catch you being lazy again, you bastards!"

The angry roar of their squad leader - Sergeant Makarov - came from behind like cannonballs.

Joss and the others kept standing still, staring ahead without saying a word, but secretly complaining in their hearts: It's unlucky to be caught by the sergeant.

The sergeant turned to them and reprimanded loudly: "Don't you guys understand? This is neither Arda nor Beilding, but Emden, the former territory of the Kent family. A lunatic loyal to the usurper comes, what if something really happens?"

Makarov reprimanded them severely.

"In this kind of place, vigilance is the top priority. If the lord's precious students are really missing a few hairs, you all come to see me, and I raise my head to see Lord Bryce. Do you understand?"

"Yes!" Joss and his comrades responded loudly.

"At night, each of you write an inspection and give it to me!"

"Yes!" There was a mournful voice in the answer.

The so-called "baby students" in Makarov's mouth were the few figures who were busy in the distance, and they all came from Wyss College.

A week ago, their platoon leader was transferred to the staff department. The new platoon leader also worked in the staff department before-the officer rotation system. This is one of the measures Schroeder has taken. Going to work in the frontline troops will enable him to gain more practical combat and work experience, so as to avoid embarrassing situations on paper.

Along with the new platoon leader came a group of students. This group of students was amazing. According to the platoon leader, they were all Earl Greyman's favorites. Battalion Commanders Bryce and Joyce even met with them personally. They had a meal.

The purpose of their coming here is to engage in "surveying and mapping". Simply put, it is surveying and mapping-drawing accurate maps.

Makarov's company was assigned a task by Bryce: to assist the group of students to complete the surveying and mapping work.

The students were divided into several groups and acted separately, and Makarov and the others also ran around with them, helping to carry tools and serving as guards.

After being caught by Makarov, Joss and the others didn't dare to slack off any more, and put all their energy into vigiling their surroundings, and it was dusk unknowingly.

It was getting late, and Makarov led Joss and others towards the students. The higher-ups ordered not to tire the lord's baby, and it was time to lead them back to the barracks.

After approaching, they did not interrupt the work of the students, but observed.

Two students stand one high and one low on the slope, each holding one end of a long bamboo pole (actually a bamboo ruler), and the other holds a wooden board (inclinometer), and keeps the lower side of the wooden board with the measuring bamboo. The ruler is parallel and consistent.

A series of engravings with equal spacing are engraved on the top of the wooden board. These engravings form a semicircle. The center of the circle is on the side of the wooden board facing the sky, and a straight line perpendicular to the two sides of the wooden board is carved from the center of the circle.

A small nail is nailed to the center of the board, and a small iron ball is hung on it with a string. The iron ball pulls the thin line straight down to the ground, and the thin line meets the straight lines perpendicular to both sides of the board at the center of the circle, forming an angle.

Makarov asked suspiciously: "What are you doing? Is this surveying and mapping?"

A student was concentrating on writing something in his notebook, when he heard Makarov's voice, he noticed someone approaching.

He cast his eyes on Makarov and the others, and smiled shyly.

"Sergeant, we are measuring the horizontal distance between two points."

Joss asked, "Horizontal distance?"

"Yes, you can see that this is a slope. The **** distance is measured directly with this bamboo ruler. We then use this inclinometer to obtain the inclination angle—the angle between the bamboo ruler and the horizontal ground. Those short lines that form a semicircle are the signs. The scale of the angle, the horizontal distance can be calculated through the **** distance and the **** angle.”

"It's amazing, is this all right?"

"Yes! This is mathematics." The student suddenly became excited, "Your lord is right, mathematics is the key to understanding everything in the world."

"Did the lord teach you?"

"Yes, the lord personally taught us about trigonometric functions. Earl Greyman knows a lot!" Having said that, several students all looked adoring.

But Makarov and others didn't know what trigonometric function they got, "Uh...why do you want to measure this so-called [horizontal distance]?"

"This is the [Orthographic Projection] method that the lord taught us. For example..."

The students holding notebooks danced and explained the principle of maps to the big soldiers.

"You put something directly under a light source. The shadow of this thing on the ground is its orthographic projection. The map we want to draw is to use this method to map some mountains, rivers, houses, roads, and rural trees on the ground. etc. are projected on a horizontal plane, and this horizontal plane is replaced by a piece of paper, so this kind of map is also called a planar topographic map.”

Joss scratched his head: "I didn't see you flying to the sky to watch the projection."

The student laughed: "Of course we can't fly to the sky to see it. We have to measure and draw bit by bit with the help of those map roots. UU Reading www.uukanshu.com"

He pointed around, and the soldiers understood what the so-called "Tugen Points" were. They were long poles erected on the ground with eye-catching flags tied on them.

"When drawing a floor plan, you must first draw the root points on the drawing, and then use these root points to map the blocks between each point in detail..."

After listening to the students talk for a long time, Makarov, Joss and others were still confused, and they couldn't understand many terms.

They have seen the maps that the other party has drawn, and they are very unfamiliar. This is very different from the maps they have seen from the officers before. The maps they have seen before are like paintings, with mountains, rivers, The buildings are very vivid and can be understood at a glance, but the accuracy of those maps is relatively poor. After reading it, you can only have a general understanding of the geographic information displayed above.

As for the maps drawn by the students, how should I put it, the whole map gives people a feeling-serious, blunt...and bad, the pictures of various images are gone, replaced by symbols, squares, straight lines and Irregular curves (which seem to be called contour lines), but according to the students, the accuracy of the maps they draw is far better than the old maps in the past.

Before the sun set, the soldiers escorted the students back to the barracks, carrying a lot of tools for surveying and mapping, such as right-angle levels, trough levels, right-anglers, flat plates, tripods and other strange instruments.

After dinner, they received a new order from the battalion headquarters: to suspend the surveying and mapping work, and the first and second battalions will start attacking Fort Byram tomorrow—it was just a feint, but enough pressure must be exerted on the Kent family to attract Bido The attention of the enemy near the fort.

The coalition forces guarding Pidtburg could hardly hold on...
