How to measure the force

1. 1. The meaning of CPU calculation once is that CPU performs "bit calculation" once, for example, 2 + 3 = 5, and binary is 0010 + 0011 = 0101. If there are three bits in total, the computer will calculate three times. 2. As for what this number is related to, that is, the higher the CPU frequency, the more the number of operations per unit time

Before the main network of IPFs filecoin was launched, the specific mining yield could not be calculated effectively and accurately, and the mining computing power of filecoin became a complex composed of bandwidth, hard disk space, network coverage and other factors

what the data storage market needs to contribute is hard disk storage space. The more hard disk space, the higher the mining capacity; Provide network bandwidth and get fil by mining bandwidth resources; The mining machine developed by interstellar continent based on the technical points disclosed in IPFs and filecoin white paper has more advantages in computing power

3. You can refer to the V-T image. If you change f to V and X to t in the above figure,
then the displacement x is the area formed by this line and X axis.
similarly, w = FX is not the same as x = VT? So w is the area formed by this line and X axis
this area is trapezoidal, the upper and lower price plus the lower price multiplied by the height divided by 2...
the above is the analogy method

there is another explanation, which is integral.. After you learn the meaning of the integral of senior three, you will further understand it

4. You can refer to the following, according to some commonly used graphics cards in the Internet bar market, sort out the price and calculation power of a related graphics card, as well as the expected return to the current period, It can be used as a reference:
power consumption: 243w
computing power: 22.4m
price of graphics card: 1999 yuan
number of eth g every 24 hours: 0.015
revenue generated every 24 hours: 24.48 yuan
expected payback time: 81.66 days
power consumption: 159w
computing power: 24.3m
price of graphics card: 1599 yuan
price of graphics card: 1599 yuan
every 24 hours Number of time digging eth: 0.017
revenue generated every 24 hours: 27.9 yuan
expected payback time: 57.31 days
video card of radon RX 480

5. blockchain is a decentralized distributed database, and its emergence is an impact on the current network environment
in the centralized management mode, the disadvantages of privacy leakage, easy to be attacked, and information opacity are inevitable, but the characteristics of blockchain technology, such as decentralization, anonymity, security, and sharing mechanism, can just solve these problems. With the graal improvement and application of blockchain projects, it will be widely used in medical, tax, logistics, payment and other fields in the future, realizing the global access of medical information, real-time update of logistics information, transparency of tax asset information, and efficient payment and settlement, which can greatly optimize the shortcomings of the existing centralized management mode
at present, many governments and enterprises have shown extremely friendly attitude towards it, and vigorously promote the application research of new technologies such as blockchain and artificial intelligence. However, the current blockchain technology is not mature enough, and there are still many defects, such as the risk of 51% computing power attack, huge full node data, slow confirmation speed, etc, These are the problems that need to be solved in the current development of blockchain technology. Although it is still imperfect, some unique characteristics it presents have indicated that it will continue to develop
with the development of blockchain technology, several upgrades have been completed, some new applications have been improved and developed, and the research and development value has been increased. In a few years or more, blockchain technology will become mature, or will be applied more widely, so as to improve people's lifestyle.

More than 500W power supply

sapphire rx580 full load power to more than 200 watts, plus CPU and other hardware power consumption, need more than 500 watts of power supply

If the power supply is

500, it is necessary to pay attention to whether it is rated power. The value of rated power is the rated voltage of the electrical appliance multiplied by the rated current. If the actual power of the graphics card is greater than the rated power, the electrical appliances may be damaged; If the actual power is less than the rated power, the graphics card can not operate normally

extended data:

the power of power supply can be divided into rated power, maximum power and peak power

rated power: the ambient temperature is between - 5 ~ 50 ℃, the input voltage is between 180V ~ 264v, and the power supply can stably output power for a long time

maximum power: at room temperature, when the input voltage is between 200V and 240V, the power supply can stably output power for a long time, and the maximum power is generally about 15% higher than the rated power. For example, the rated power of Xingu nuclear power 325pq is 250W, and the maximum power is 287w, which is close to 300W

peak power: the maximum power that the power supply can achieve in a very short time, and the time can only last between a few seconds and 30 seconds. The peak power is related to the operating environment and conditions, which is not a definite value, but the peak power can be very large, which is very easy to mislead users. For example, the rated power of Xingu nuclear power 325pq is 250W, and the peak power reaches 350W. Obviously, only the rated power and maximum power have practical significance

7. The principle of coin'an mining trading function is based on liquidity pool. There are two kinds of tokens in each liquidity pool. The relative number of tokens will determine the price between them. As long as there are corresponding assets in the pool, transactions can always be made.

8. Does kilogram change to n? 1kg force = 10N

9. Generally, bolts are added at the connecting hole position, the force is measured with a tension meter, and then multiplied by half of the diameter of the bolt hole distribution is the starting friction torque.
