370 graphics card dynamometer

1. The figure in the picture can't be seen clearly
if the center of gravity is O, the force on fulcrum A is: weight times (Bo divided by ab)

2. Situation setting:
a solid triangle fulcrum; An object weighs g and will be lifted as a source of resistance. The force application point is at one end of the rod. The length of a rod without mass is L. the force application point of a person is at the other end of the rod. As a power to lift an object, now we study where the fulcrum receives the maximum and minimum pressure on the rod< Research methods:
is the force balance
problem discussion:
1. In view of the size and direction of the force, it is necessary to decompose the force (power and resistance), synthesize the effective force to the fulcrum, and get the pressure on the fulcrum
2. The pressure of the pole on the fulcrum is its supporting force on the pole. The direction of the force is generally upward. With the prying of the pole, the direction of the supporting force is always perpendicular to the pole; In addition, there needs to be friction at the fulcrum
3. Therefore, with the lever prying, the pressure on the fulcrum will change, no matter where the fulcrum is
simplified mode:
keep the lever in a horizontal state, the direction of gravity a (resistance) and hand pressure B (power) of the object is vertical to the downward direction of the lever (the lever is horizontal), and the direction of the supporting force C (the pressure on the fulcrum) of the fulcrum to the lever is vertical to the upward direction of the lever, so there is no need to decompose and synthesize the force, Then a + B = C. now a is constant, and B changes with the fulcrum. Because it's vertical, friction doesn't have to be taken into account
conclusion:
the closer the fulcrum is to the object, the smaller the pressure on the fulcrum (because the labor-saving lever B is smaller),
the closer the fulcrum is to the power application point, the greater the pressure on the fulcrum (because the labor-saving lever B is larger),
when the fulcrum is in the middle of the rod, because a = B, the pressure on the fulcrum is twice the gravity of the object (because it is an equal arm lever)

remarks:
when the pole is not horizontal, the force analysis is relatively simple, but it is cumbersome and omitted.

5. R9 370 video card has 2G and 4G video memory two versions, the specific situation can use Master Lu and other software to check.

6. This amd R9 370 graphics card has a good performance, which is equivalent to the gtx950. However, this graphics card has been discontinued. Now we can only buy second-hand R9 370 graphics card and play large stand-alone games,

7. There are parameter data on ZOL~

8. R9
370 is a new graphics card, which is to replace R9
270 and 270x. For n card, it's gtx750ti.... But this card is more cost-effective

9. Of course, it doesn't get stuck

10. Although AMD's graphics cards in the past two years are vest, in theory, R9 370 is better
