How to calculate the force perpendicular to the inclined plane
Publish: 2021-05-25 11:54:24
1. Draw the angle between gravity, inclined elastic force, the opposite direction of elastic force and gravity θ So, the elasticity is equal to g × cos θ
2. When I came to see it, there was no answer. When I submitted it, I didn't know if anyone was ahead of my younger brother
I'd like to know your current identity: junior high school? Because this kind of problem is really simple
1. The resultant force of friction and supporting force is exactly the same as that of gravity: collinear + reverse + magnitude
2. As long as you think the friction can be large enough (actually impossible), unless 90 °， Otherwise, the balance of the three forces can be achieved
3. There must be something wrong with your stress analysis. Gravity is vertical and downward; The supporting force is perpendicular to the inclined plane and points from the inclined plane to the center of mass of the object; The friction is parallel to the inclined plane and upward
4. The component of gravity along the slope is GSIN θ， The component of gravity perpendicular to the slope is GCOS θ You're wrong
5. Equilibrium is vector, not scalar F + F = GCOS θ+ Gsin θ
equilibrium along an inclined plane: component of gravity GSIN θ， Friction GSIN θ Equilibrium perpendicular to the inclined plane: component of gravity GCOS θ， Support GCOS θ In the opposite direction)

Apply with the household register
Article 10 of the resident identity card law of the people's Republic of China stipulates that when applying for a resident identity card, the registration form for the application of the resident identity card shall be filled in and the household register shall be submitted for examination< Article 7 stipulates that a citizen shall apply to the public security organ of the place where his permanent residence is located for a resident identity card within three months from the date of reaching the age of 16. For citizens under the age of 16, their guardians shall apply for resident identity cards on their behalf
4. With all e respect, you can tell from a glance that your graphics card is fake...
if you just bought it and the price is more than 150, I suggest you give it back. You can buy HD5750 for about 180 yuan. Its performance is much better than this one
after installation, please unplug the cable on the graphics card and connect it directly to the 6pin power cable. If there is no 6pin cable in the original power supply, you'd better not use this kind of graphics card that needs external power supply, unless you don't mind the power boom.

5. Postpartum rehabilitation belongs to postpartum fitness private ecation. Yoga clubs generally have private rehabilitation courses.
6. Students use ASUS 660ti, now popular big game basic take all,
it has ultra-high 1137mhz core frequency
rate and directcu direct touch cooling technology support, high performance, good cooling, and the media said this is the high-end card
representative!

7.
This is the GPU core of n-card, but it is by no means the core of gtx660ti. There is no architecture number on it. It must be an old card of gt400series
this proct is the GPU core of gtx660ti Public Edition. You can compare it
8. Shixin will be all professional post natal Yoga places, as well as professional coaches for guidance, I have carried out yoga here, the body repair effect is very good.
9. As far as Master Lu is concerned, his score is only 30% reliable. There is no explanation for this. Second, gtx660ti is a high-end graphics card. Although it has no fever, it can be easily solved by any game and application now, and there is no problem at all. Another is that the computer itself is a platform, its performance does not depend on a higher performance hardware, but on the lowest performance one. Even if your CPU graphics card is the most high-end, but your memory is very low-end, the performance of such a computer is rubbish. So you don't have to rush to a conclusion, first see if your configuration is reasonable. The second is driver. Every hardware has its own performance driver. If the driver is not right, the performance will be greatly reced. There is also the temperature of the computer. No matter how high the computer temperature is, the performance will be greatly reced
10. Gtx460 is a 10-year-old medium and high-end graphics card, which can be used in battlefield 3 efficiently. The X-mode of 3D 11 is 1400 points (CPU is i52300). After changing to gtx660ti, the X-mode running score of 3D 11 is 2600 (CPU or i52300), and its performance is about twice that of 460, which is similar to that of the top Fermi framework gtx580. However, NVIDIA gtx6 uses Kepler architecture, and its running ability is better than the game performance. The actual game ability is about 170% of gtx460. The FPS of gtx460 is stable between 40-75 in 1080p resolution, and it will drop frames when the game is fierce. The gtx660ti maintains around 50-77, which is much better than gtx460, and the 900p situation is much better than gtx460. But when gtx660ti plays Island 3, it often drops frames at 1080p, which should be e to its 192 bit width.
