32t parameters of T1 miner

1. Crane selection
the theoretical tonnage of truck crane multiplied by 3, and then divided by the weight to be lifted can get the distance, and divided by the distance can get the weight, but the actual capacity of the crane can not reach the calculated result, so the weight of the main boom and the weight of the hook should be included
the weight of the object to be lifted is 11T, and the distance between the center of the pipe to be installed and the center of the crane is 8m. The calculation of the type of crane to be selected is as follows:
calculation of the maximum lifting tonnage of a and 25t cranes
25t × 3=75
75/8=9.375t
9.35t × 75% = 7.03t
the 25t crane is adopted, the working range is 8m, and the maximum lifting tonnage is 7T
for the calculation of DN250 pipe weight, the pipe wall thickness is 12mm and the length of each section is 11mm; So the weight of each pipe is 0.849t
25t crane: 7.03t > 0.849 T
therefore, 25t crane is selected to complete the pipeline hoisting work.

2. According to GB / T 5231-2001, the chemical composition of T1 is Cu + Ag & gt= 99.95% P>= 0.001 Bi>= 0.001 Sb>= 0.002 As>= 0.002 Fe>= 0.005 Ni>= 0.002 Pb>= 0.003 Sn>= 0.002 S>= 0.005 Zn>= 0.005 O>= 0.02 total impurities & gt= After annealing at 700 ℃ for 30 min, the measured resistivity is 0.0168 μ ohm · M

3. Three parameters, lifting capacity of 32 tons, span of 18.4 meters, double girder bridge crane, do you need girder calculation?

4. 32T(32/10) = 80-90KW
16T(16/5) = 60-70KW

5. First of all, CPU is the central processing unit, and GPU is the independent image processor in CPU

secondly, there is no GPU in some CPUs (AMD makes more GPUs and CPUs integrated together, and now Intel is also studying to integrate the two)

moreover, both CPU and GPU are chips with computing power. CPU processes instruction operation (execution) as heavy sum numerical operation, while GPU is not so powerful. Graphics numerical calculation is the core

the speed of different types of operations also determines their capabilities. They have their own advantages. Therefore, the division of CPU and GPU can be roughly divided in this way. CPU is mainly good at operating system, system software, application program, general computing, system control, etc

artificial intelligence, physical simulation and so on in the game; 3D modeling ray tracing rendering

virtualization technology language abstract hardware, running multiple operating systems or multiple copies of an operating system at the same time, etc

GPU is good at graphic matrix computing, non graphic parallel numerical computing and high-end 3D games

the integration of mobile phones is very high, and the core is called SOC

it integrates CPU, GPU, decoder, WiFi and baseband

if you simply look at the quality of CPU, the simplest thing is to remember some common brands, the latest eight core model of MediaTek. The performance is still good, but it is only good. The architecture of CPU is A7 and its performance is limited<

in a balanced computing computer system, CPU and GPU still perform their respective ties. In addition to graphics computing, GPU may mainly focus on high-performance parallel numerical computing with high efficiency and low cost in the future to help CPU share this type of computing

improve the performance of the system. The current typical application is still high-end 3D games, an efficient GPU with an efficient CPU, the overall efficiency of 3D games can be guaranteed

some time ago, CPU and GPU exceeded their authority, so there was the important saying of CPU and GPU on the Internet.

6. Refer to Q235 / Q345 plate

7. Just delete the parameter t

8.

T 1 + T 2 is used to find the distance, and T 1 T 2 is used to find the proct of distances

1. The geometric meaning of parameters is shown in the figure:

extended data

1. Parameters, also called parameter variables, are variables. When we study the current problems, we are concerned about the changes of some variables and the relationship between them. One or some of them are called independent variables, and the other or some of them are called dependent variables. If we introce one or some other variables to describe the changes of independent variables and dependent variables, the introced variables are not the variables that must be studied in the current problem. We call such variables parametric variables or parameters. English Name: parameter

2. Parameter is an option that can be used in many mechanical settings or maintenance. Literally, it is data for reference, but sometimes it is not all data. For a given application, it can be a given constant value; In general, it can be a variable used to control other quantities that change with it. In short, the parameters are for our reference

resources : Network: parameters

9. A coordinate is (2 + 3t1, - 3 + 4T1), B coordinate is (2 + 3t2, - 3 + 4T2)
| ab | = {[2 + 3t1 - (2 + 3t2)] ^ 2 + [- 3 + 4T1 - (- 3 + 4T2)] ^ 2} = 5 (T1 - T2)

10.

The absolute value of T1-T2 difference represents the distance between two points on the line:

x = a + T cos α

y=b+t sin α

If it is not in this form, the meaning of T will change

substitute T1 into the parameter equation to get x1, Y1, then T2 to get X2, Y2, finally use the two-point distance formula

The involute of

circle x = R (COS φ+φ sin φ y=r(sin φ-φ cos φφ ∈[0,2 π R is the radius of the base circle φ Is a parameter

Extended data:

Taylor formula with remainder term is strictly proved by definite integral, and the area of trapezoid with curved edge is expressed by mean value theorem of differential and integral, and the formulas of area, curved surface area and solid volume between planar curves are derived

The

parameter curve can also be a function of more than one parameter. For example, a parametric surface is a function of two parameters (s, t) or (U, V)

The variable t in the

function is a "participating variable" relative to the variables X and Y representing the geometric position of the particle. In this kind of practical problems, the parameter variables are abstracted into mathematics and become parameters. The task of the parameters in the parametric equation we learned is to communicate the relations between variables X, y and some constants, so as to provide convenience for the study of the shape and properties of curves
