370 graphics card runs eth computing power

2. X5550, quad core, eight thread, X58 motherboard, these are 2009 hardware. They are very old. If you buy them, you can't help it. If you don't buy them, don't buy them. The R9 370 4G graphics card is about 75000 to 80000 points. Although your configuration is old, you can use the R9 370 graphics card,

3. 370 graphics card, mining? You make me laugh for a while
People's high-end cards are called mining. You can only play with mud.

4. In consideration of the same synchronous and continuous related system, if the object keeps moving around the fulcrum, If the acceleration vector of the center of gravity of the system object is a (the vector sum of rotation acceleration and centripetal acceleration)
then f-joint = am

any force can be reflected in the center of gravity
f-joint = f-joint + f-joint
so f-joint = am-f-joint

for example:
there is an experimental mechanism in the automotive design center, which is a group of transmission intermediate gear shafts, There are three gears and a cam in the middle gear shaft which are under unbalanced force ring the test experiment. Gear 1 (with meshing radius of R1) is used to receive the drive. For example, the change gear system is subject to the downward meshing force of the left clutch drive gear F1
gear 2 (with meshing radius of R2) is used to transmit the main load, For example, the automobile load worm synchronous gear
receives the downward meshing force F2 of the right load gear
the gear 3 (meshing radius is R3) is transferred to the secondary load, for example, the small generator spindle gear
receives the rightward meshing force F3 of the upper meshing gear
the cam (eccentricity is R4) is used for revolution detection and hydraulic force supply, and receives the constant left spring force F4 (F4), It is known that the mass of the whole wheel group is m, and the average radius of inertia is r
where the total mass of the gear and shaft is M1, the eccentric wheel is M4, and M = M1 + M4
at a certain stage, the angular acceleration of the gear shaft is j in the process of accelerating rotation, and it reaches the maximum value at a certain moment ω Angular velocity, the highest part of the cam faces to the right
solution: at this moment, the fulcrum of the gear shaft is forced, (ignoring the bearing friction)
note: (it is not necessary to pass the gravity and the bearing support force, In other words, the supporting force overcomes the gravity and forms the fulcrum compound force)

1: according to my method,
the eccentric distance of the whole center of gravity = M4 * R4 / M = R4 * M4 / m, the cam orientation is the instantaneous eccentric orientation (horizontal right)
let it be expressed by R below, r = R4 * M4 / M
in addition, according to the driving force analysis, The rotation direction of the system is anticlockwise, so the center of gravity is doing upward acceleration J
and left centripetal acceleration X= ωω R
then the sum of global acceleration vector = √ (JJ + XX) = √ (JJ + XX)+ ωωωω RR)
so f = am = m √ (JJ)+ ωωωω RR)
other forces except fulcrum
have downward F1 + F2
rightward f3-f4
when vector representation is used, f branch = fhe-f1-f2-f3-f4 (all with transverse vector representation)
the operation process must be all transformed into complex trigonometric function representation, which is somewhat complicated
in order to simplify, we divide it into horizontal and plumb direction (horizontal to right is positive, horizontal to right is positive, horizontal to right is positive, horizontal to right is positive, horizontal to right is positive, horizontal to right is positive, horizontal to right is positive, horizontal to right is positive, The vertical component of F is + MJ, the horizontal component is - MX, the vertical component is - F1, the vertical component is - F2, the horizontal component is F3, the horizontal component is - F4, The same below)
vertical component of f-branch = MJ + F1 + F2

f-branch vector = √ (f-branch horizontal ^ 2 + f-branch vertical ^ 2) direction = arctan (f-branch vertical / f-branch horizontal)

2: combined with moment calculation (take the value as an example)
If M1 = 8kg M4 = 2kg M = M1 + M4 = 10kg r = 0.25 R4 = 0.04m
R1 = 0.2m R2 = 0.4 R3 = 0.6
F1 = 1000N F2 = 400N F3 = 50N F4 = 100N
then F1 moment is 1000 * 0.2 = 200N
F 2 torque is 400 * 0.4 = 160nm
F3 torque is 50 * 0.6 = 30nm
F4 without torque, the rotation torque is 200-160-30 = 10nm
J = 10nm / M / r = 10 / 10 / 0.25 = 4radians / s
If acceleration is 2.5 seconds to ω= Because r = r4m4 / M = 0.04 * 2 / 8 = 0.01M
x= ωω R = 1 m / s, s
then f-joint horizontal = - MX = - 10 * 1 = - 10N, f-joint vertical = + MJ = 10 * 4 = 40n
then f-branch horizontal = f4-mx-f3 = 100-10-50 = 40n (positive value indicates right direction)
f-branch vertical = MJ + F1 + F2 = 40 + 1000 + 400 = 1440n (positive direction upward)
the force on f-branch is slightly right inclined upward

I hope you can understand it, just for example

Lever principle is also known as "lever balance condition". In order to balance the lever, the two torques (the proct of force and arm of force) acting on the lever must be equal. That is: power × Power arm = resistance × The resistance arm is expressed as F1 · L1 = F2 · L2. Where F1 is power, L1 is power arm, F2 is resistance and L2 is resistance arm

when using the lever, in order to save effort, the lever with the power arm longer than the resistance arm should be used; If you want to save distance, you should use a lever whose power arm is shorter than the resistance arm. Therefore, the use of leverage can save labor and distance. However, in order to save effort, we must move more distance; If you want to move less distance, you have to work harder

the fulcrum of the lever does not have to be in the middle. The system that satisfies the following three points is basically the lever: fulcrum, force application point and force bearing point

Based on the "center of gravity" theory, Archimedes discovered the lever principle, that is, "when two weights are balanced, their distance from the fulcrum is inversely proportional to their weight." Archimedes' research on leverage not only stays in theory, but also makes a series of inventions based on this principle

In the battle to protect Syracuse from the attack of the Roman Navy, Archimedes used the lever principle to make a long-distance and short-range catapult, and used it to shoot all kinds of missiles and boulders to attack the enemy, which blocked the Romans from outside Syracuse for three years

R9 370 is equivalent to gtx660. It is a medium and high-end independent graphics card. The following is the ladder diagram of graphics card:

7. The reason why the Ministry of instry and information technology (MIIT) puts instry and information technology together is that the MIIT, namely the MIIT, is a newly established central ministry under the background of China's "big ministry" reform in 2008, and is also established according to the government institutional reform plan of the 11th National People's Congress
since China's accession to the WTO, China is in an important stage of accelerated instrialization. It is an important task at present and in the future to take a new road of instrialization, promote the integration of informatization and instrialization, promote the combination of high-tech and traditional instrial transformation, and promote instry from large to strong. It is not only the general trend but also the only way to set up the Ministry of instry and information technology and speed up the pace of new instrialization
in the past, the national development and Reform Commission, the national defense science, technology and Instry Commission, and the information instry department were respectively responsible for the management of instrial instry, which was decentralized and not concive to the coordinated development of instry
in order to strengthen the overall planning and coordination, it is necessary to integrate the relevant responsibilities, so the Ministry of instry and information technology was established
the central government has integrated the instrial management responsibilities of the national development and Reform Commission, the responsibilities of the science, technology and Instry Commission for national defense except for nuclear power management, and the responsibilities of the former Ministry of information instry and the Information Work Office of the State Council, and assigned them to the Ministry of instry and information technology. In addition, the State Bureau of science, technology and instry for national defense will be set up and managed by the Ministry of instry and information technology. In addition, the State Tobacco Monopoly Bureau is managed by the Ministry of instry and information technology. The Commission of science, technology and instry for national defense, the Ministry of information instry and the Information Office of the State Council will no longer be retained.

The Bureau of instry and information technology has a good development prospect and is a very good government unit. In fact, the salary is similar to that of other bureaus. They deal with enterprises more often. Sometimes they need to do data analysis and work together with enterprises

therefore, even in the Bureau of instry and information technology, different people have completely different prospects. Some are staff members all their lives, while others are promoted quickly. It's about opportunities, ability and leadership. It's not good to generalize

extended data

the main responsibilities are as follows:

1. Formulate and implement instrial planning, instrial policies and standards; Monitor the daily operation of the instry; Promote the development and independent innovation of major technical equipment; Managing the communications instry; To guide and promote information construction; Coordinate and maintain national information security

As an instry management department, it mainly manages the planning, policies and standards, guides the development of the instry, but does not interfere in the proction and operation activities of enterprises. Among the key universities in China, there are 7 universities directly under the Ministry of instry and information technology and 5 universities jointly built by the Ministry of instry and information technology

3. Undertake the responsibility of communication network security and related information security management, coordinate the maintenance of national information security and the construction of national information security guarantee system, guide and supervise the security guarantee work of important information systems and basic information networks of government departments and key instries, and coordinate the handling of major events of network and information security
