Chapter 800

“It is such a master. According to some data reports, the reasonable explanation is that the earth’s rotation speed is not particularly fast enough. The gravity of the earth will pull people on the surface of the earth, so the people there will not be thrown out.”

“It is based on Newtonian mechanics.” Jiang Cheng suddenly wanted to understand.

The centrifugal force generated by the rotation of the earth has a certain relationship with the mass of the object, the radius of the earth, the latitude, and the rotation period of the earth. It can be inferred and judged according to Newtonian mechanics and finally verified.

Jiang Cheng picked up a pen and prepared to record his judgment and thoughts.

“Then suppose that the mass of a person is 70 kilograms, and that person is located on the equator, then the “centrifugal force” produced by the rotation of the earth is 2 cattle.” Jiang Cheng muttered to himself.

“So, on the other hand, according to the law of universal gravitation, the gravitational force exerted by the earth on a person weighing 60 kilograms is about 589 N, which is much greater than the “centrifugal force.” Therefore, people on the earth will not Fly into the air.”

“So, can I set the value of the transmitter to between 600 and 700 Ng?”

“However, if you want people on the equator to be thrown out, how much speed does the earth have to reach?”

Jiang Cheng knew that the faster the earth’s rotation speed, the greater the “centrifugal force” produced, until this force finally exceeds the gravitational force, the people on the equator will not be able to be pulled by gravity.

Therefore, people will fly into the air and continue to make circular motions around the earth, with gravity acting as a centripetal force.

Jiang Cheng immediately substituted the data and can calculate that the linear velocity of the earth’s equatorial line is about seven kilometers per second.

In fact, the first cosmic speed at this time is exactly the speed of the earth’s first equatorial line. In this case, the earth can rotate around its axis of rotation in less than one and a half hours.

At this time, if you are thrown into the air, only people on the equator will be the only ones who are at higher latitudes, because the earth’s rotation speed is slower, so gravity can pull people and objects there.

So can the end of my transmitter on the earth be set up on the equator? After all, if the equator is closest to the axis of rotation, the error rate will be much smaller, which will ensure safety even more.

So if this is the case, the time for the earth to rotate once is 24 hours, which is our day, then put the transmitter terminal on the equator, we can determine the mass and the earth’s radius, latitude, and rotation period. NS.

Obviously, the radius of the earth is fixed, our latitude is calculated according to the equator, and the rotation period has been calculated for 24 hours, so now it is the material of the transmitter that should be considered. The quality of the object can be taken into consideration only when the materials used are determined.

Thinking of this, Jiang Cheng has some difficulties. Now there is no material to provide for his own use. Is it necessary to use titanium alloy? However, one end of the transmitter should be connected to the armor of the soldiers on the earth, which means that one end is on the earth and the other is in space.

Then the materials at these two ends cannot be chosen exactly the same, because the mass response of the materials on the earth and in space is completely different.

Jiang Cheng fell silent at this time. After thinking about it, he suddenly shouted: “¨. I know, I know, I know what can be done.”.
