Course detail

Machine Design - Mechanical Drives

FSI-6KT-AAcad. year: 2023/2024

The course provides an overview of machine components used to transmit power and rotary motion, such as gears, shaft clutches, brakes and flywheels. Attention is paid mainly to understanding their function and mastering the methodology used in their design. The course integrates knowledge gained in the theoretical subjects of the bachelor's degree in mechanical engineering, especially in 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 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.

Aims
