Course detail

Machine Design and Machine Elements

FSI-CKP Acad. year: 2026/2027 Winter semester

The course focuses on the design and assessment of basic machine components and joints, considering their function, strength, and service life. The aim is to integrate knowledge from mechanics, elasticity and strength of materials, and materials engineering to master the methodology of structural and strength design of machine parts, supports, and joints, with an emphasis on engineering practice.

Prerequisites

Planned learning activities and teaching methods

Assesment methods and criteria linked to learning outcomes

The classification is based on two written tests at predetermined dates, usually in the middle and end of the semester. The control test consists of theoretical questions and calculation examples. The condition for obtaining the credit is to obtain at least 50% of points from both tests. The resulting score corresponds to the ECTS classification. The student is allowed to write a correction test in the date specified by the teacher, usually in the exam period. Participation in lectures is recommended, attendance at seminars is compulsory – two absences are allowed.

Aims

The aim of the course is to teach students the basics of strength and structural design of machine components, enabling them to independently assess simple machine assemblies. After completing the course, students will understand the causes of component failure under static and fatigue loads and will be able to design and verify the integrity of basic machine elements, including axles and shafts, joints, springs, bearings, and other components.
