Jiayi came to the front of the pendulum and first measured the pendulum length. No surprises, as measured before, it was calculated as the length of a single pendulum for one second.

The gravity coefficients in various places on the planet are not consistent. The pendulum length of the pendulum clock of Jiayi and their Chamber of Commerce actually takes only one greatest common divisor. When used in actual use in various places, if the pendulum clock time is not accurate, the pendulum length can be manually adjusted. The pendulum length here in the college has been remeasured after the gravity coefficient is recalculated, and the accuracy is much higher.

However, even so, no one dares to guarantee that a certain time will be accurate. First, the calculation result of the pendulum theorem is only an approximation value and is not very accurate. Second, there are various external factors that cannot be an ideal state. For example, in order to offset the influence of air resistance, the pendulum is relatively heavy.

Almost everyone has heard of the butterfly effect. Slight changes under initial conditions can drive long-term huge chain reactions of the entire system. This does not mean that a variable will definitely cause a huge chain reaction, but far more than one butterfly flaps its wings to affect a thing.

The same is true for the pendulum. Even if you try your best to achieve the most ideal conditions, you cannot completely remove interference. Seasons, temperature and humidity, geomagnetic deflection, and even the equipment is a kind of interference, and you can only get an approximate value.

Therefore, there is also a device for adjusting the length of time on this pendulum system. There is a knob. Every time you rotate it, it can adjust the speed or slowness by about 0.2 seconds, and 0.2 seconds a day. There is a sundial at the attic on the top of the tower, which is used to calibrate the time.

After this clock tower is built, it is estimated that people will need to be maintained. Although there is no need to wind it up, at least you have to come over to calibrate the time every once in a while.

There were more than Jiayi who inspected the pendulum. After Jiayi checked the pendulum, the others also checked the gear structure, mechanical transmission structure, magic transmission structure and other parts.

After Jiayi handed over his inspection results to Seusli, he came to the attic on the top to see the teachers install huge copper bells. In fact, it can also be called golden bells. It is not metal or gold, because these bells are doped with gold for casting. The so-called 8k and 9k gold content is only 20 to 30%. Even if the gold content of these copper bells is lower, it will not be much lower. At least, there are always 2 or 3k. In this way, the gold used by these bells must be calculated in tons.

Thinking about it, it's really expensive. With the more expensive magic metals mixed in it, Jiayi felt that his financial resources were reluctant to make such a "golden bell", and there were a few more people who would not go bankrupt. (Forget it, gold is 200 million ton and 300 million yuan per ton. For these five bells, the price of gold is at least 1 billion rmb. Isn't it too expensive? md.)

As soon as Jia walked to Orlando, he asked, "Teacher, does this master clock have any special effects?"

Jiayi asked McCree and the others last time, and they were so angry that they were so mysterious that they refused to say that they had met Orlando now, and their relationship was closer. They just happened to ask. Orlando had suffered a little loss last time and had been recuperating at home, without receiving anyone. This was the first time that he had appeared since then.

However, Jiayi still thought so beautifully. These teachers probably worked together for a long time, and they had a tacit understanding with each other, and even had a bad taste.

Orlando asked: "Didn't you ask McCree and others? The magic circle of the main clock needs to be connected to the magic network of the elemental pool, otherwise it will not be activated. He won't have tried it, right?"

Jiayi said: "I tried it, but it was Mr. McCree who tried it alone. We were not here. I asked him about the magic effect of the master clock and he didn't even mention it. He just said it would be seen later."

"Then you say wait." Orlando didn't care at all about his own disciples who were in the house. The answer given was the same as McCree and the others. "If you know it too early, there would be no surprises. Haven't you seen the magic circle inside the clock yourself? Didn't you see anything?"

"No." Jiayi shook his head, "Teacher McCree has been holding the bronze bell, and he has seen it once."

After saying that, Jia looked at McCree, as if he was reporting to him in person.

While checking the inspection report summarized by Husley, McCree smiled and said, "This is a surprise for you. When it is officially used later, you will know what the effect will be."

Jiayi felt that his curiosity could not be satisfied and no longer spoke, so as not to ask for the more he begged, the more proud these teachers with bad tastes would be.

The bell was quickly installed, and five huge "golden bells" hung upside down on the top of the tower. Because the top of the tower is a loft supported by pillars and has no walls, these bells can be seen even under the tower outside. These bells are all new, with bursts of precious light coming out of the surface, which gives a feeling of golden light shining in the sun, but it is not as dazzling as the sunlight reflected by the mirror, but it looks soft.

Thanks to this magical world, Jiayi would have doubted whether the top of the tower could hold on to such huge copper bells hanging on the top of the tower. The five copper bells total at least 5 or 60 tons. Even the modern concrete structure in the previous life would probably have to be able to withstand the steel frame beams. Otherwise, over time, the roof would definitely not be able to withstand it.

"Xuesley, Passabay, you guys will take people to get the second hand outside down, and we will start to officially run the entire system to see how it works." McCree ordered.

Moer asked strangely: "What are you doing if you drop the second hand? Are you afraid of lack of motivation?"

"I guess I'm afraid that the second hand is too big, so I'll see that the clock tower has started running." Orlando knew more about McCree and expressed his thoughts.

McCree turned around and gave him a thumbs up, then calibrated the time, and canceled the bell ringing switch. This system is very complicated, and even the bell control is divided into many types. Each bell has its own control device to control when they ring the bell and how many times they ring. Each bell can be turned off separately.

The cancellation of the second hand has nothing to do with Jiayi because he can't fly. When designing the second hand, he considered whether he wouldn't want it, because the pointer outside was very huge, and the second hand was about 5 meters long and very heavy. If it was running continuously, the power requirement was very huge. Fortunately, we had magic power, and there was a whole small element pool behind it, with energy continuously, so we kept the second hand.

Soon, Husley and the others carried a few thick hands back into the room one after another, and then McCree activated the calibrated pendulum clock.

Although the element pool was connected, there was no sound and light effect. Only a sound and light sound was heard. As the pendulum swinged, the entire system began to run. Although there was no minute hand, the part that controlled the minute hand was still rotating. Jiayi and the others were inside, and they could directly observe the gears that controlled the minute hand rotation. Everything was not half-pointed from the expected one. The entire device had actually been previewed several times when it was underground.

As the pendulum swings, the escapement device begins to release the gear in a click-and-click cycle. The gear amplifies the force on the gear through a power amplification device, and then transmits it to the end-most gear structure. The end-most gear structure controls three pointers, and the second hand is made into 60 grids in length, turning once a second, and then triggers the minute hand to rotate after 60 seconds. However, every time the minute hand turns 1 grid, the hour hand will deflect a little bit until after 12 grids in minute hand, the hour hand turns one grid.

Everyone stared at this system and brought a magic hourglass timer. Half an hour passed. The pendulum clock system was always very normal, without any problems, and there was no deviation from the timing of the magic hourglass. At least, it could not be seen by the naked eye. It also compared with the sundial on the rooftop, but there was no problem. At least, the timing was still very accurate in these 30 minutes.

McCree looked at the rotating gear, then looked around for a week and said, "We have succeeded. Install the second hand immediately. When 12 o'clock, the entire clock will be officially started."
Chapter completed!
