Chapter 290 Artillery Range Measurement
“What? Suspend the surveying and mapping operations and let us return to Huxin Town?”
The students were stunned, the news came too suddenly.
Joss helplessly spread his hands to them: "This is an order from above, and we have just received it."
He complained secretly in his heart, why did I have to convey this unpleasant message? news.
"Tomorrow or the day after tomorrow we will head south to fight the enemy. Only the necessary garrison force will be left here, which may not be able to guarantee your safety."
The leading student was the first to react. Whispered: "Mr. Jos... maybe we can..."
Before he finished speaking, Jos shook his head like a rattle: "I'm just a private, I can't decide anything, you guys If you have any ideas, please go to Bryce or Joyce. Only they can decide whether you should stay or go."
The leading student nodded: "Thank you for the reminder, we will discuss it here first. For a moment..."
Jos said good night and left the room, leaving behind the students who were discussing things in low voices.
"We can't just leave like this. Only a small part of the surveying and mapping work has been completed."
"If we go back in such a dejected state, our group's performance will definitely be at the bottom."
"Really It's unlucky that I picked up such a place by lot."
"Let's discuss it with Mr. Blas and Mr. Joyce tomorrow."
......
Early the next morning, Bryce and Joyce were discussing the matter of going south. They were originally scheduled to leave today, but later found that a lot of unplanned preparations were needed.
The guards standing guard outside came to report that it was students from Weiss College who requested to see them.
Bryce thought for a moment and said, "Those students? Let them in." The Earl still valued these students.
"What? No!"
After the students came in, they made a request that surprised Bryce - they actually wanted to stay here to complete their surveying and mapping homework.
"Huxin Town has repeatedly asked us to ensure your safety. I can't let you run around without guards."
The leading student - the leader of their group - is named Nick, with an anxious look on his face, begged again: "Mr. Bryce, thank you for your concern for our safety, but mapping is a very important task, and we can't give up halfway. Alda is developing mining and exploring for minerals. Inseparable from maps, maps can also provide convenience for merchants to travel around and promote the development of commerce. It is also of great significance to your army. With accurate maps, it will be much more convenient to arrange troops and formulate battle plans. The Lord's Mansion takes this matter very seriously, otherwise it would not send us students who have not completed our studies."
Bryce just shook his head: "Even if you have 10,000 reasons, I will. I can’t just let you run around.”
The two sides were in a stalemate for a while, but neither could convince the other.
A student suddenly suggested: "Since we can't be left alone in the rear, let's follow you to the south! Anyway, the geography there will have to be surveyed and mapped sooner or later."
"Hey? This is a good idea! Please let us follow you!"
Nick agreed with his classmates' idea, and other students also nodded.
"It's still nonsense! Are we going to fight? Do you think we are going to enjoy the mountains and rivers?"
Bryce frowned and continued to object, although he had 100% confidence in his troops. He had confidence, and it was a feint attack, but the battlefield was changing rapidly, and he couldn't guarantee that one person and two people would not make any mistakes.
Seeing that he could not convince Bryce, Nick slapped his forehead and thought of a good idea.
"Master Bryce, what do you think of this? If you take us there, we will teach your artillerymen a simple distance measurement method. Standing on the artillery position without moving, they can accurately... er... it is relatively accurate. Measure the distance to the target."
"Oh?" Bryce and Joyce pricked up their ears at the same time, Nick's suggestion hit their pain point.
The artillery troops of the Arda army relied on the naked eye to estimate the distance to the target when aiming, which required a high level of experience for the gunners. Some experienced gunners with extremely high "shooting talent" can estimate the accuracy of the shot with just a glance. They can test fire a shot first, and then slightly adjust the pitch angle or charge amount to steadily fire the second shot. gun. However, there are very few such talents, and most gunners-especially the new recruits-have to move the impact point closer to the target one shot after another.
If there was a way to measure the range relatively accurately while standing on the artillery position, it would take the role of artillery to a higher level.
Nick smiled proudly, and the two officers were intrigued by him.
Bryce asked: "What method can you tell me?"
Nick shook his head: "Then you have to promise us that you can go south with the army."
Bryce is a little angry, you bastard boy, you don’t even have hair yet, you dare to negotiate terms with me, for such an important skill like artillery rangefinding, I just deducted it from you, Lord, and you have nothing to say.
However, it was a joke to think that I, a lieutenant colonel, and a bunch of teenagers were getting angry, so I suppressed my unhappy emotions.
He looked at Joyce. The third battalion commander, who was not much older than these students, had "agree" written all over his eyes.
"Ahem!" Bryce cleared his throat: "Okay, I agree with you to move with the troops."
"Is the Lieutenant Colonel telling the truth?"
Bryce blew his beard and glared: "Will my dignified commander of the First Battalion still lie to you kids? But you, tell me how to measure the distance first!"
"Yeah. ! ”
A group of students cheered and their surveying and mapping homework could continue.
Although Joyce now serves as the battalion commander, as Schroeder's former knight retinue, he was also very young. Seeing the cheers of these students who were a few years younger than him, he was very touched in his heart.
He took a pen and paper and put it on the table, smiled and said to Nick: "Congratulations, our Commander Bryce is not easy to talk to on weekdays. But don't be busy celebrating, give it to us first Tell me, if my guess is correct, it’s probably using the so-called [mathematics], right?”
“Pop!” Nick snapped his fingers and said, “That’s true!”
He picked up the paper and started drawing on it, "This is a method we often use when surveying and mapping..."
Everyone leaned over and saw that Nick had drawn a triangle on the paper, but this triangle was a bit special. Two of its sides intersected perpendicularly. One of the two sides was very long and the other was very short.
Students all recognize that this is called a right triangle.
"Suppose your artillery is deployed here!" Nick drew a circle at the right angle.
Then he controlled the tip of the pen to move slowly from the right angle along the longer right-angled side (strand) to the smaller acute angle, and finally stopped at the tip of the corner, "This is your bombing target. "
"This line segment," Nick thickened the long right-angled edge (strand) where the pen tip passed, "is the distance between the artillery and the target. "
"And this line segment," Nick thickened the short right-angled side (hook line), "is a known fixed distance directly to the side of the gun. To facilitate calculation, it can be an integer, such as one meter or Two meters, you can call it [baseline]"
"Now, just measure the size of this angle," Nick circled the larger acute angle, "and then combine it with the one meter or two meters. Knowing the fixed distance..."
"The straight-line distance between the artillery and the target can be measured."
He carefully traced the long right-angled edge (stranded line). A few strokes.
“That’s the line!”
