Course detail

Technical Mechanics

FEKT-BPC-TMBAcad. year: 2023/2024

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.

Rules for evaluation and completion of the course

Final evaluation of this subject consist of the following parts:
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.
Numerical exercises are compulsory. The content and forms of instruction in the evaluated course are specified by a regulation issued by the lecturer responsible for the course and updated for every academic year.

Aims

The objective of the subject is to offer the students the basic information concerning mechanics of non-rigid bodies, mechanics of liquids and thermomechanics.
Student is able to:
- enumerate and describe the basic cases of simple stress,
- explain terms: stress, main stress, normal stress, shear stress,
- express Hook´s law and define its validity,
- compute the pressure force of liquid on the general plane surface,
- use for the dynamics of fluids the Bernoulli equation,
- define the thermodynamics laws and describe the individual quantity,
- illustrate the different thermal processes of ideal gasses in p-V and T-s diagram,
- illustrate the different thermal processes of real gasses and steam in p-V, T-s and i-s diagram,
- compute the basic parameters of thermal cycles of gas turbine, steam turbine and heat exchangers.
