How to calculate the tightening force of two tiles

1. It's so simple. First of all, for the cylinder you selected, he will definitely provide the parameters of pushing and pulling force under how much pressure. If you can't calculate, I will give you a formula, f = PS = P * (PI) * r * r, the area of cylinder diameter for pushing out, the area of cylinder diameter for retracting minus the area of push rod. You can calculate the pushing and pulling force. As for pushing each other, I don't care if you don't interact with each other, you are just like a wall, and the forces on both sides are the same, How much on one side is how much on the other side. If one side is big and the other side is small, one side will definitely run. It's not whether it's one or not. It's interaction

2. This is a very complex problem, so I won't mention it before high school, even college physics doesn't have it (college physics only has the calculation method of magnetic field generated by current, but magnet doesn't), unless it is a related major.. This is related to some properties of the magnet itself, the shape of the magnet, the magnetic medium in the middle (whether there is ferromagnetic material in the middle), and whether there is magnetization. There may be some empirical formulas for magnets with fixed shape and strength
I only know how to calculate the torque of the motor. As for me, I think it's difficult to calculate the torque of the motor for non related majors. It's more complicated because only very close can there be a force. If it's very close, it's necessary to carry out triple integral calculation according to the shape. It's very troublesome, and it's even more difficult to calculate if the shape is irregular....

3. The tightening force of bearing bush has clear requirements in the assembly drawing of bearing bush. Generally, the tightening force of cylindrical bearing is 0.10 ~ 0.15 mm, and that of spherical bearing is 0.03 ~ 0.07 mm< The measuring steps are as follows:
1. Assemble the upper and lower half bearing shells and fasten the bolts on the joint surface
2. Place two lead wires with a diameter of 1 mm at the top pad iron (the top of the spherical shell for spherical shell)
3. Put four uniform networks of 0.5mm stainless steel plates in front of and behind the joint surfaces of bearing blocks on both sides of the bearing bush
4. Fasten the bearing covers and tighten the bolts on the joint surfaces evenly
5. Use a feeler gauge to check whether there is a uniform clearance of 0.5mm at the four corners of the joint surface
6. Loosen the bolts and lift off the bearing cover
7. Measure the thickness of flattened lead wire, take at least three points for each lead wire, measure three values, and take the average value, and then calculate the average value of two lead wires. The tightening force is equal to the average value of gasket thickness minus lead wire thickness.

4. Chasing girls depends on whether you have this need. I can understand your feelings very well, because some people just want to find someone to take care of themselves. Some people just like to be free and live according to their own ideas, so you don't have to pay too much attention to other people's gossip. You can see that you are still young, so it doesn't matter whether you chase girls or not. You can tell her what you think, go after her and see her reaction. If she also likes you, she also wants to get along with you. Naturally, she will find a way to solve the problem with her boyfriend. If she steps on two boats, then this kind of girl is not good for dating. It's a relief to give up early. The object of falling in love must choose the right person, Otherwise, it's a waste of time and feelings for you. It's a very painful thing. Once the feelings are put in, it's very difficult to get out. It takes a long time and a lot of courage. For those who are worth it, you can go on. For those who are not worth it, you should end it as soon as possible. In fact, you lack self-confidence, find a point or an aspect that you are good at, and find your self-confidence, Everything can be solved, that is, to break through oneself. You lack self-confidence, so you dare not express, resulting in poor expression ability. The more you feel that you can't do, the more you hide yourself. Then you don't give people a sense of existence at all. How do people attach importance to you? I'm from the past. I know that for the boy who doesn't like you, you should first figure out his personality and then consider whether you want to take the initiative to try to be with him, OK? Otherwise, when the time comes, they will be mped, saying that men don't have a good thing, they are all scum men. Haven't you talked to anyone for half a year? It's normal for people to ignore you. Oh, when you think of someone else, you go to them. If you don't want them to ignore you for half a year, what do you think of your girlfriend as? If you call, you will come; if you wave, you will go. If you miss others, they will cater to you when you are happy. If you don't want others, they should disappear in front of you, right? If you send a red envelope, people will give you a few words. For the sake of the red envelope. Who can't live with money these days? If I don't give you a red envelope, I'll ignore you, right? He proved to be a smart girlfriend. If you're smart, give up. Sincerely find one. Treat others sincerely. We must be sincere and single-minded about our feelings. It's not that I said that you should change your personality when you call on your girlfriend. Otherwise, it will be difficult in the future. I'm sorry to talk too much.

5. It's the changed data before and after the modification. In other words, you can pause the game, and then enter your number of gold coins, and then play for a while. When the number of gold coins changes, you can pause again, and enter the changed number of gold coins. Then the interface will display some data like things, and all the points will be changed to 999999 and so on. Take a look at the game again, there are so many gold coins.
