Chapter 137: Big Toy!

Alan returned to the second floor and retrieved the drawings for the Ferris wheel and roller coaster from the system.

When he returned downstairs, he saw that Shaman was lecturing his two younger brothers.

“Shaman, take a look at these two blueprints first.”

As he spoke, he handed over the drawings in his hand, interrupting Shaman’s lecturing to the two young men.

“Saber, Sager, don’t be nervous. Shaman only looks fierce, but he’s actually very easy to get along with.”

He turned his head and said to the two goblin children in a friendly manner.

Saber nodded gratefully at Alan, while Sager remained seated at the side, smiling shyly.

“Alan, this toy called roller coaster doesn’t seem to have any effect on mages. The effect mentioned in the blueprint should be very difficult to achieve…”

Shaman looked at the blueprint in his hand and said carefully.

“Hehe, you don’t know that. I think that if the roller coaster is successfully built, Uncle Wayne will be invited to add a magic array around the roller coaster. This way, even mages won’t be able to escape the attraction of centrifugal force and gravity.”

Alan told Shaman his original plan. The smile on his face made Shaman feel that he was up to no good.

“These two blueprints look simple, but they involve a lot of knowledge.”

Shaman felt that the things on the blueprints looked simply, but he had no idea where to start.

“These two things involve a lot of knowledge. If I don’t study them properly, I really don’t think anyone can build these two big things.”

Alan knew that these large-scale amusement facilities in his previous life were not built casually. Many of the projects involved a lot of physics knowledge.

“You two, did you hear that? Since Alan has given such an important task to you, then study it well and build it. Do you understand?”

Although Shaman was also very interested in these new blueprints, the most important thing to him was still the rail car. Just from Alan’s few words, he could tell that the steam engine and the internal combustion engine was definitely an important thing in the future.

However, his energy was limited. While he was studying this project, he did not have the extra time and energy to study these large toys. Since Alan was willing to trust his two younger brothers, then it would not be a problem for him to keep an eye on them.

“Yes, brother. Don’t worry. We will study hard and study hard. We will definitely not disappoint you and Mr. Alan’s expectations.”

Saber knew that he and his brother had finally obtained the initial recognition, and his expression became much more excited. He did not care about his shyness and quickly promised Shaman and Alan loudly.

“Mr. Alan, don’t worry!”

Sager also mustered up his courage and promised.

“I already said that you don’t have to be so polite. We will meet and get along with each other in the future. Just relax a little.”

Alan felt a little uncomfortable with the way the two brothers addressed him. Just think about it. From his age, he might not have lived as long as the twin goblin brothers.

The four of them looked at the blueprint and discussed it for a long time. This time, with the blueprint in hand, the title they wore was finally useful.

Alan’s explanation of the relevant physics knowledge made the goblins immerse themselves in it. They worked hard to absorb and learn this new subject.

The small train on the roller coaster relied on the thrust of a mechanical device to push it to the highest point. However, after the first descent, there was no longer any device to provide power for it.

In fact, from this moment on, the only “engine” that would drive it along the track would be gravitational energy, it was formed by the process of converting gravitational energy into kinetic energy and kinetic energy into gravitational potential energy.

The first type of energy, gravitational energy, was the energy of an object due to its position, due to its height and the acceleration produced by gravity.

In the case of a roller coaster, its heat energy reached its maximum at its highest point, that was when it climbed to the top of a “hill”.

When the roller coaster starts to fall, its potential energy continued to decrease, because its height falls. But the energy does not disappear but was converted into kinetic energy.

However, in the process of energy conversion, heat was generated due to the friction between the roller coaster wheels and the tracks, thus depleting a small amount of mechanical energy, that was kinetic energy and potential energy.

The feeling of falling was the strongest in the rear carriage of the roller coaster, because the last carriage passes through the highest point faster than the front carriage of the roller coaster. This was due to gravity acting on the center of mass of the roller coaster.

The person in the last carriage would have the strongest feeling of being thrown away, because the center of mass was accelerating downwards. The wheels of the rear carriage were firmly fastened to the track, otherwise the small carriage may be thrown off the track when it reached near the peak.

The situation of the front carriage was different. Its center of mass was “behind”. For a short period of time, although it was in a state of decline, it had to “wait” for the center of mass to cross the high point and be pushed by gravity.

When it reached the “crazy circle”, the roller coaster that was moving along the straight track suddenly turned upwards. At this time, the passengers would have a feeling of being pressed onto the track because there was a kind of apparent centrifugal force. In fact, on the circular track, there was a centripetal force due to the interaction between the track and the roller coaster.

The circular track was slightly oval in shape and was designed to “balance” the braking effect of gravity.

When the roller coaster reached the highest point of the circular track, it would actually slow down, but this phenomenon would decrease if the bending was less severe. Once the roller coaster had completed its journey, the mechanical braking device would safely stop the roller coaster.

The speed reduction was controlled by the cylinder.

When Alan explained these principles, his face was full of excitement. He could even imagine the people of this world feeling the embarrassment of the centrifugal force of the planet on the roller coaster. After all, fear was something that could not be controlled by humans.

The Ferris wheel was essentially a large-scale rotating wheel-shaped mechanical construction facility. On the edge of the Ferris wheel were cabins for passengers to ride in. They were usually used as an active observation platform.

According to the difference in the operating mechanism, the Ferris wheel could be divided into three types: gravity Ferris wheel, “spokeless” Ferris wheel, and observation Ferris wheel.

The gravity Ferris wheel’s cabin was hung on the wheel to maintain the level of the slide axis with gravity. The observation Ferris wheel’s cabin was suspended outside the wheel, requiring a more complicated linkage-type mechanical structure, the level of the wheel was adjusted in sync with the position of the carriage.

The blueprints for the three Ferris wheels were included. After discussing with the goblins, Alan decided on the type of Ferris wheel they wanted to build. But it was agreed that in the end, only one Ferris wheel would be built in Rock City. After all, there were too many and there was no need for it.

“Alright, that’s about it. The rest is up to you guys.”

After Alan handed everything that he knew to the goblins, the rest was not up to him. He just left it to the goblins..
