Chapter 302 Improved Trebuchet

Felissa finally moved into the manor. It was a decision she made after careful consideration. It was only for three days. If her move in could make Blake feel at ease, then why not do it.

Olivia arranged for a carriage to deliver Felissa's necessities and let Felissa stay in her room.

"That's not good," Felissa declined. "Just give me another room."

"The other rooms are not good," Olivia said forcefully, "I am a sister and I want to give you the best."

After hearing this, Felicia accepted her kindness.

"Speaking of which," Felissa asked, remembering Blake's gaffe, "uncle seems to attach great importance to this press conference."

When mentioning this, Olivia couldn't help but feel a little depressed: "Because many people think that the mother's investment in her father is a waste, her mother also bears a lot of pressure. Although my father doesn't care much about other people's evaluations,

After all, I am worried about my mother."

Felicia was surprised. She originally thought that Blake was the kind of person who ignored everything outside the window and only focused on research. But he actually knew about Viscount Cliff's situation?

"I understand," Felissa nodded, "I will do my best."

Originally, she just thought about passing through these three days. She had only seen trebuchets in movies and TV series in her previous life, but thinking about it, she knew that the trebuchets in movies and TV series were all products of artistic processing, and it didn't matter whether they could be used or not.

Easy to say.

But, no matter what, her vision is definitely broader than that of people in this world.

However, she underestimated the enthusiasm and perseverance of the researchers headed by Blake. That night, she made a spoon-shaped trebuchet. It looked very simple. She pressed the pedal with her hand to launch it. The distance of the projectile was only fifteen kilograms of stone.

It was thrown seven or eight meters.

Blake asked Felissa how to improve it. The projection distance of ten meters would definitely not be able to meet expectations. It would have to be at least one hundred meters, and the stone would have to be heavier.

Blake asked Felissa how to improve.

Felissa looked confused: How could she know? With her pitiful and meager knowledge of physics, she only knew a little bit about it, and she couldn't remember the deeper things.

So she thought about it for a long time and could only tentatively say: "Well, lengthen it?"

The force arm of this simple trebuchet is one meter long, and the long and short axes are divided into three to seven ratios. A basket is configured at the end of the long axis, where stones can be placed. However, due to the size of the basket, the size of the stones is also limited.

Limitation. Since the moment arm is only one meter long, the height of the short shaft is not high, about 60 centimeters high. When throwing a stone, step on the long shaft and throw the stone.

Seeing that she was indeed ignorant, Blake understood. He was afraid that he had seen the wrong person. Felissa might have accidentally learned about the "Leverage Principle" from somewhere, and then taught it to them, but she only knew one of the Leverage Principles and the others.

Don't understand anything.

Blake didn't offend Felissa because of this. In his opinion, being able to propose the principle of leverage was already a great help. If they were left to think about it on their own, he didn't know how long it would take them to think of this.

Blake left her behind and started a discussion with his colleagues.

Felissa, who was listening to their speech, also regretted why she didn't study science and engineering in the first place, otherwise she would be more or less useful at this time.

In the end, they came to the conclusion: instead of lengthening the length first, they still used the one-meter-long lever arm and made two more trebuchets with the ratio of 46 to 28 respectively. They compared the three trebuchets to see which one could throw better.

Far.

The one with a ratio of 30 to 7 is called the experimental group, the one with a ratio of 28 to 46 is called the control group one and two respectively.

Although it is tempting to say that these three can all be called the experimental group, as long as they are happy.

Felissa was already drowsy and sleepy. Seeing that no one was paying attention to her, she calmly returned to the room to prepare for bed.

Although I was lying on the bed, I couldn't fall asleep for some reason. My thoughts always turned to the researchers who were still working.

The guilt of not being able to do anything weighed on her heart, making her toss and turn, and she couldn't help but want to get up and watch others study the trebuchet.

Because her heart was not at peace, Felissa didn't sleep well either. She woke up very early. After waking up, she freshened up and went downstairs to see how their research was going.

The research atmosphere is still in full swing, but there seem to be fewer people. They probably went to rest. After all, my body can't support it if I keep researching all the time.

Felissa stood aside quietly, and then she saw something.

The force arm of the new trebuchet is still one meter, and the ratio is nine to one, nine on the long axis and one on the short axis. The throwing distance is indeed longer.

"Change someone, change someone!" She heard someone shouting breathlessly, "I can't do it anymore!"

Felicia looked over and saw the thin researcher holding his knees with his hands, panting and looking like he would fall to the ground at any time.

He should have lost his strength by constantly pressing the pedal.

If you want the trebuchet to be thrown farther, one person's strength is limited, but it is inconvenient if multiple people press the pedal. It would be nice if there was a fixed force to press the pedal.

It's not good to press the pedal. Pressing it once or twice is fine. If you press it too much, it will definitely crush the pedal. Felicia drew a force analysis diagram on the paper. The short axis will be subject to a downward force. This

Force can come from pressure, and it can also come from tension.

Yes...weighing weights.

Felissa's eyes lit up. She found Blake and proposed her idea: "Hang a heavy object on the short axis. When pulling it up, put a stone on the long axis. After placing it, let go and throw the stone naturally.

out."

Blake pondered: "But if you do this, you will need to build a high platform so that it is easier to pull up the short shaft."

Felicia turned her head and looked at the trebuchet: "Why not get a pulley?"

Blake asked, "What is a pulley?"

She still has an impression of the pulleys in junior high school, and pulleys have been widely used in her previous life. It can be said to be common sense, so she will never forget it even if she wants to.

This world doesn't even have pulleys, which shows how backward technology is.

It cannot be said that there is no such thing. After all, there is also an operation of throwing a rope into the air, passing it through a horizontal bar, and then standing on the ground and pulling the rope to lift the heavy object up, but no one has studied why.

Everyone thinks this is something that is obvious at a glance.

Felissa drew a picture. The purpose of the fixed pulley is to change the direction of the force. Even if it is a heavy object of several hundred kilograms, it can be pulled by ten people pulling the rope together. And when the pedal is pressed down, the force is easy to be uneven.

, but putting down the rope is different. Pressing the pedal is a continuous process, but putting down the rope is an instantaneous action. It is definitely easier to put down the rope.

Black found a treasure and drew a design drawing based on Felissa's simple drawing, adding a lot of details, such as adding a stable structure of the support, marking the rope material, etc.
