How to log out of mobile mining

1. By paying attention to the changes of various data and comparing historical data, we can confirm the current market trend and overall mood.

3. In the design of cast-in-place one-way slab ribbed beam floor, the transmission of vertical load and the distribution of load effect are directly related to the load nature, load distribution, component support type, etc., which should be obtained by mechanical analysis according to the correctly established model and the method specified in the code. Different load combinations are used in different limit state calculation. The so-called "coefficient" is not fixed. The landlord asked in general, but could not answer in depth.

4. First, analyze which part of the load of the plate is transmitted to the beam, and then the beam should be a simply supported beam. The line load of the plate load and the beam self weight is applied in the stress analysis. The force of the beam support is the force that he transmits to the wall. You should be a brick concrete structure. The frame structure generally has no force on the wall

5. The size provided in the picture is not complete, so it is impossible to calculate the area of this secondary beam bearing the floor
let the area of this range be a square meter, and the basic combination value of the load on the slab surface be s (KN / M & # 178;), If the length of the secondary beam is LN, the calculated linear load transferred from the slab to the secondary beam is a · s / ln (KN / M). The dead weight of the secondary beam is not included here.

6.

Determination of calculated load:

the main failure mode of transmission system parts of construction machinery is fatigue failure. The parts often work under full load and suffer a large impact load, so the smaller value of the maximum static torque transmitted by the engine and the torque determined by the adhesion condition should be taken as the calculation torque

In fact, the coefficient of adhesion is a variable value with the ground conditions in a large range, so it is mainly calculated from the torque transmitted by the engine, and the calculation of adhesion is only used for checking when necessary

The calculation of the torque of each component can be determined as follows:

gearbox: MJ = MF (or MT)

where MJ is the calculated torque

MF -- rated torque of engine

MT -- output torque of torque converter

main drive: MJ = mfib1 η B1 (or mtib1) η B1)

where η B1 -- transmission efficiency of the first gear of the gearbox

final drive: MJ = 0.5mfib1 η b1izc η ZC

where η ZC -- transmission efficiency of main drive

after determining the distribution of transmission ratio and transmission diagram, we can design and calculate various parts of the transmission system, such as gears, shafts, bearings, etc

load type:

1, photoelectric infrared load

one of the advantages of Tactical UAV is that it can be close to the target to carry out reconnaissance, and small aircraft can even fly over the target to shoot at a distance of 100 ~ 200m. With the development of photoelectric technology, the weight, volume and cost of TV cameras and infrared thermal imagers are greatly reced. These reconnaissance equipment have been loaded on small or even micro UAVs

Synthetic aperture radar (SAR) can work effectively at night and in bad weather. It can penetrate through clouds, fog and battlefield shelter, and image in a large range with high resolution. With the development of light antenna and compact signal processing device and the rection of cost, SAR has been able to be equipped on Tactical UAV

3. The wavelength of lidar is short, which can not only detect the targets under the cluster leaves, but also classify the targets, providing accurate target information for the ground forces to carry out the engagement

7. Byzantine, Istanbul, Constantinople are one place, Budapest is the capital of Hungary, the common ground is that they were occupied by the Ottoman Empire
