Engineering
2 слайд
Today machines have to withstand such tremendous stresses and to be able of such complex motions, that complicated and specialized calculations are needed in the design of even quite a simple machine like a motor-car engine
3 слайд
So, as engineering progressed, engineers must become even more scientific and specialized. Today the branches of engineering are so wide, that one cannot give a satisfactory classification. But we may try to divide it into uses. We should mention the following divisions:
4 слайд
Mechanical engineering. Steam engines; internal combustion engines; turbines (steam, gas, water);
Electrical engineering;
Power; generators; motors; transformers; transmission (power lines and so on);
Electronics: radio, radar, television;
Civil engineering: Dams; tunnels, roads, and so on;
Structural engineering: the structural details of all large buildings and bridges;
Chemical engineering;
5 слайд
Any of these branches of engineering may require the special services of the following specialists:
The metallurgist
The strength materials expert
The thermodynamics or heat expert;
The mechanics or machines expert;
The various production engineering experts such as the engineering designer or the tool designer;
The mathematician in engineering problems and many more.
6 слайд
The engineer must also deal with the economists to assure himself that he is produsing what is waned, and economically
The scientific and technological progress will continue in engineering along two main headlines. Firstly, it is automation. Secondly, raising the reliability extending the service life of machines.
7 слайд
New technologies and equipment have been designed for most branches of engineering. In the shortest possible time we are to start producing new generators of machines and equipment.
Large reserves in extending service life for machines can be found in the process of designing. Specialists should pay more attention to quality, and not to the mere number of new machines, apparatures and materials.
