Course detail

Machine Design - Machine Elements

FSI-5KSAcad. year: 2023/2024

The aim of the course is to provide an overview of machine parts and joints like mechanical springs, bearings, axles and shafts and bolted, riveted, welded and bonded joints. Attention is paid especially to get understanding of their function and learn the methods used in their design process. The course integrates the knowledge acquired in theoretical courses of Mechanical Engineering Bachelor's degree programme, particularly in branches of materials science and mechanics.

Rules for evaluation and completion of the course

The course is completed by taking an exam after the previous awarding of the credit.
The credit confirms that the student actively participated in the work during the semester and received at least 50 points out of a maximum of 100 points. The criterion of point evaluation is the degree of ability to solve assigned tasks correctly and independently. The points from the credit do not transfer to the exam.
The exam investigates the complex mastery of the subject matter defined in the course card and especially the ability to apply the acquired knowledge independently and creatively. The level of mastery of the issue is evaluated in the range of 0 to 100 points. The student must obtain at least 50 points out of maximum of 100 points.
The exam has a written and an oral part. The written part of the exam is mandatory for all students. It consists of four calculation tasks. The oral part of the exam is voluntary.
Lectures: attendance is voluntary.
Exercises: attendance is mandatory and controlled by the teacher. Maximum of two absences are allowed in total. In case of long-term absence, compensation for missed classes is in the competence of the course guarantor.


Students will be able to analyse and design basic machine components such as mechanical joints, energy accumulators, bearings and seals.
- Understanding the mechanisms and causes of failure of machine parts.
- Knowledge of the principle, calculation and use of basic machine parts.
- Ability to apply the acquired knowledge in the design of new machines and equipment.
