MANKIND DEVELOPMENT ON THE BASIS
OF SCIENTIFIC AND TECHNOLOGICAL PROGRESS
The current global state of engineering technologies reflects foremost the
progress made during the 20th century. Striking results have been achieved in
many fields, but there are also signs of a surging number of negative by-prod-
ucts —
environmental pollution, accidents, ever-increasing depletion of global
resources, etc. Thus, a new concept for scientific and technological progress is
urgently required. It is to assure consistent development of the mankind on the
basis of scientific and technological progress. Within this context,
mechanical
engineering plays a very important role.
Mechanical engineering is seen as the scientific and technological basis
for new machinery enhancements due to the development and use of new ma-
terials and advanced technologies. The key goals of engineering are to create
new machines that are streamlined in terms of efficiency, reliability, safety,
economical and ecological performance.
In
other words, machines should comply with high ecological and safety
standards. It triggers development of new and advanced materials with prop-
erties such as high strength and stiffness, low density, high inter nal damping,
high
corrosion and wear resistance, and radiation stability. An example of this
could be the common use of highly energy-efficient machines based on vibra-
tion action in mining and in the construction of roads and buildings. A lot of
problems in different areas are to be solved within mechanical engineering.

Another tendency in modern engineering is to automate all production
processes in order to reduce or eliminate hard physical labour, to increase
productivity, to enhance
the quality of products, and to ensure maximum
output in production on large scale; to support or replace human intellectual
work by using machines for solving logical problems. Mechanical engineering
gained the lead in many engineering fields such as optimum machine design,
computer-aided design (CAD), experimental mechanics, vibroacoustics, bio-
mechanical systems comprising “man, machine and environment”,
strength
of materials, problems of reliability and wear resistance, engineering safety,
environmental protection, and information technologies.
