Course detail
Technical Mechanics
FEKT-BPC-TMBAcad. year: 2025/2026
The subject is focused on three parts of the mechanics: the mechanics of non-rigid bodies, mechanics of fluids and thermomechanics.
In the mechanics of non-rigid bodies it is paid attention to the basic cases of simple stress, strength designing of elements, combined stress.
In the mechanics of fluids the student gains in knowledge of statics and dynamics of fluids (for example continuity equation, Bernoulli equation).
The last part of the subject is devoted to the thermomechanics, chiefly the laws of thermodynamics, thermal processes, basic thermal cycles, compressors, heat transfer, heat exchangers.
In the numerical exercises the mentioned problematic is solved in the specific examples.
This subject makes the important basic for the further subjects.
