Course detail
Machine Design - Machine Elements
FSI-5KSAcad. year: 2022/2023
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.

Assesment methods and criteria linked to learning outcomes
The credit confirms that the student actively participated in the work during the semester and received at least 15 points out of a maximum of 30 points. The criterion of point evaluation is the degree of ability to solve assigned tasks correctly and independently.
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 70 points. The student must obtain at least 35 points out of maximum of 70 points.
The exam has a written and an oral part. The written part of the exam is mandatory for all students. It consists of three calculation tasks and one question. The oral part of the exam is voluntary.
