Course detail

Selected chapters from machine design - machine elements

FSI-0KS Acad. year: 2023/2024 Winter semester

The course extends and deepens skills especially in solving computational problems in the field of basic machine components and joints, such as springs, bearings, axles and shafts and bolted and welded connections. The course is a complement to the lecture, practice and home preparation of the course Machine design – machine components (5KS).

Aims

 Graduates will be able to analyse and design basic machine elements such as shafts, mechanical and welded joints, energy accumulators and bearings.

Specification of controlled education, way of implementation and compensation for absences

Lectures: attendance at lectures is mandatory and controlled by the lecturer. In case of long-term absence, the replacement of missed classes is the responsibility of the course supervisor.
