Force calculator app

1. Lightcoin calculator calculated for reference only, not necessarily real income, recommend several mining graphics card to you, hd7990 R9 290x gold slave miner data card R9 280x

2. Thank you for your concern. The calculation is wrong. We will go online after the adjustment is accurate

3. Used Renren mine, not bad, you can try, thank you for our support, I hope my answer can be useful, welcome to ask, thank you again!

4. Very good, because it is a small agile game, more exciting. Recommend you a game: Bush selling hot dogs. Very interesting

5. Rnd is indicated in the function key of calculator ()

it is a function to generate random numbers between 0 〈 x 〈 1.

6. Mathematics still needs to be studied well. The first is to find the standard deviation, and the second is the change of arithmetic mean. These excel have ready-made functions, which can be easily calculated, and are generally used to calculate the uncertainty components caused by measurement repeatability in uncertainty analysis.

7. Curious passing by, no corresponding exercise book? Looking for software? I think it's easy to find the right books to train and strengthen the computing ability in the bookstore

8. The two theories are respectively
1) the surrounding rock pressure is calculated according to the loose body theory when the overlying strata of the underground structure is thin. It is generally considered that the total weight of overburden rock acts on the underground structure. At this time, the surrounding rock pressure on the underground structure is the weight of the overburden rock column. Deep buried structure means that the buried depth of the underground structure is so deep that the friction resistance on both sides far exceeds the weight of the sliding column. The surrounding rock pressure of deep buried structure is to study the pressure phenomenon in a local range above the underground cavern. The stability of part of the rock mass is called rock arch. Only the weight of the rock mass below proces pressure on the structure, which is called pressure arch, It is a quadratic parabolic curve. Horizontal surrounding rock pressure is only considered for soft rock. The acting force on the lining floor e to the surrounding rock uplift is called the bottom surrounding rock pressure
2) the surrounding rock pressure is calculated according to the elastic-plastic body theory

9. This software is written by professionals, please support domestic software. Software is not expensive, for curtain wall designers, this money is just a few days' salary.. Please support the author. I am the first batch of Huibao users, feel that the author's attitude to the software is very serious, also very serious to customers
it seems to be 1200 / yard at present. Well, it's not very expensive
