Course detail
Technical Mechanics
FEKT-BPC-TMBAcad. year: 2022/2023
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.

Prerequisites
Co-requisites
Planned learning activities and teaching methods
Teaching methods include lectures and numerical exercises. Course is taking advantage of e-learning (Moodle) system.
Student have to write 6 single projects (physical problems). There are 3 continuous tests in the numerical exercises.
Assesment methods and criteria linked to learning outcomes
a) numerical exercises - continuous tests, individual work,
b) examination - written part (arithmetical problem) and oral part.
Requirements for successful completion of this subject are determined by a annual regulation of the lecturer.
