How to calculate FN in sliding friction

1. Let me tell you a good way. I dare to say that only after I have personally experienced it

when I first grew corns, I pasted chicken eye ointment, but the effect was not good, and it also corroded the skin. Later, my mother didn't know where to find the folk prescription, so she got me a thick cactus meat and fixed it on the corns (adhesive tape or transparent glue). At first, I didn't have much confidence in this method, because after sticking it overnight, the corns were only white and soft by the cactus juice, So I didn't use it any more, but after three or four days, I found that the thing in the middle was getting dark slowly (of course, there was some blood in it when I reced it), and it began to separate from the surrounding part. I buttoned it with my nails, and the thing in the middle really took off from the surrounding meat, leaving only a little meat at the bottom, which I pulled down with my teeth, There was a big hole in the place where the corns were growing, and there was a lot of blood. But in one night, the hole healed. Now there is only one red spot left, and it doesn't hurt. I think it must be the effect of cactus juice. My personal experience, you can have a try, maybe it will also work for you.

2. Hello
the most simple and effective way is to apply chicken eye ointment, but be patient and stick it until the corns rot. L

3. This project has basically stalled. You can't withdraw cash, you can only hedge. If you have the ability to pull thousands of people into the pit, you can get change. I'll introce you a new opportunity. The principal can go in and out freely at any time, and you can't lock up your position

The public address is assigned by the inter NIC, which is mainly for the organizations that register and apply to the inter NIC. There are mainly five types of addresses: A, B, C, D, e:

1, a: the address range is 1.0.0 to 127.255.255, which is mainly assigned to a large number of hosts and a small number of LAN networks

Class B: the address range is 128.0.0.0 to 191.255.255.255, which is generally used for international large companies and government agencies

Class C: the address range is 192.0.0.0 to 223.255.255.255, which is used for general small company campus network research institutions, etc

Class D: address ranges from 224.0.0.0 to 239.255.255.255, which is also called broadcast address for special purposes

Class E: the address range is 240.0.0.0 to 255.255.255.255

1, public network and Intranet

are two access modes of Internet. In the public network access mode, the IP address obtained by the computer on the Internet is the non reserved address on the Internet, and the computer on the public network and other computers on the Internet can freely access each other

2. Private address

belongs to non registered address, which is specially used for internal use of the organization. There are mainly three types: A, B and C. The A-type address range is 10.0.0.0-10.255.255.255, the B-type address range is 172.16.0.0-172.31.255.255, and the C-type address range is 192.168.0.0-192.168.255.255

127.0.0.0 to 127.255.255.255 are system loopback addresses

public IP_ Network

5. This IP is arbitrary. If this IP belongs to your optical cat, it is the public IP. If it belongs to your router, it is the intranet IP

6. IP is the abbreviation of English Internet protocol, which means "the protocol of interconnection between networks", that is, the protocol designed for communication between computer networks. In the Internet, it is a set of rules that can make all computer networks connected to the Internet communicate with each other. It stipulates the rules that computers should abide by when communicating on the Internet. Any computer system proced by any manufacturer can be interconnected with the Internet as long as it complies with the IP protocol. It is precisely because of the IP protocol that the Internet has rapidly developed into the largest and open computer communication network in the world. Therefore, IP protocol can also be called "Internet Protocol"

the public address is in the charge of inter NIC. These IP addresses are assigned to the organizations that register and apply to the inter NIC. Direct access to the Internet through it

private address is a non registered address, which is specially used for internal use of organizations

class a address (0.0.0.0-127.255.255.255), in which private address is (10.0.0.0-10.255.255)
class B address (128.0.0.0-191.255.255.255), in which private address is (172.16.0.0-172.31.255.255)
class C address (192.0.0.0-223.255.255.255), in which private address is (192.168.0.0-192.168.255.255)

7. At present, the IPv4 addresses are almost used up. Now we are studying the next generation of IPv6 addresses. I don't know how many are there, but we can tell you which network segments are public networks
11.0.0-126.255.255.255
128.0.0-191.255.255.255
193.0.0.0-223.255.255.255

8. 1. The public address is the responsibility of the inter NIC. These IP addresses are assigned to the organizations that register and apply to the inter NIC. Direct access to the Internet through it. Class a IP address range 1.0.0.1-126.255.255.254 class B IP address range 128.1.0.1-191.254.255.254 class C IP address range 192.0.1.1-223.255.254.2542, private address belongs to non registered address, which is specially used for internal use of organizations. The following lists the retained internal private addresses: class a 10.0.0.0--10.255.255 class B 172.16.0.0--172.31.255.255 class C 192.168.0.0--192.168.255.255

9. The IP address beginning with 222.42 is the public IP
the IP address segment is the IP address of Hubei Province

10. 60.180.165.44 is public IP. Is this assigned to you by the operator? Ping doesn't work. It may be that Ping is forbidden, or the address is not configured on the router
