Слайд 3So, 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:
Слайд 4
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;
Слайд 5Any 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.
Слайд 6 The engineer must also deal with the economists to
assure himself that he is produsing what is waned, and
economicallyThe 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.
Слайд 7New 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.
