Mechanics and thermodynamics

Subject description

MECHANICS: kinematics, Newton's laws, angular momentum, law of gravity, kinetic and potential energy, conservation of energy, harmonic oscillations, damped oscillations, forced oscillation, coupled oscillation, introduction to continuum  mechanics, introduction to fluid mechanics (Bernoulli equation, viscosity, Poiseuille – Hagen equation), surface tension (Laplace equation, Young equation), Stokes law, quadratic friction law, mechanical waves

THERMODYNAMICS: kinetic theory of gases,

first  law of  thermodynamics, entropy and second law of  thermodynamics, thermodynamic functions, thermodynamic equilibrium of  the system, heat transfer, heat engines, thermal expansion of  solids and liquids

The subject is taught in programs

Objectives and competences

– to acquire a general education in technical and natural sciences

– to gain better understanding of  theoretical and experimental methods in  natural and technical sciences.

Teaching and learning methods

 Lectures, tutorials, demonstrative experiments during lectures and  lectures of  visiting professors from abroad.

Expected study results

Successful completion of  the course will provide the students with:

– education in fundamental  mechanics and thermodynamics, preparing  them for a future as problem solvers or researchers in industry and in research institutes

– a good basic education in mechanics and thermodynamics  suitable for a career in high-technology industry.


After completion of  the course the  students should be able to/of:

-use  the basic  theoretical tools of  mechanics and thermodynamics   that are needed for the more specialised courses in electrical engineering,
-application of   the basic laws of mechanics and thermodynamics  to  solve  general problems  in electrical engineering,

– solve practical problems in engineering , which prepare  the students for independent  research and development  work  in  reserach institutes and

in the industry ,

– solve complex  interdisciplinary engineering  problems,  requiring a  knowledge and understanding  of   thermodynamics and mechanics, as well as experience with analytical tools from the field of physics.
