Course objectives

Students will get to know the basic theoretical and practical methods required in machine design, the methodology and documentation of machine measurement with a special purpose machine, and the operation of machines with the help of some specific application examples.

Course content

Lectures

1. The concept of a machine, their classification. Uniform operation of the machine. 2. Physical quantities and their relationships. 3. Concepts of mechanical work, power, efficiency. Task (hand winch). 4. Friction and rolling resistance. 5. Modification and transmission of mechanical work (stationary and moving pulley). 6. Friction and gear drive, belt drive. Task (friction on slope). 7. Belt drive. Compression coil spring. Task (belt drive, gear drive). 8. Operation of the machine at a uniformly variable speed. Basic knowledge of transmission. Hydrostatics, pressure measurement. Task (U-pipe, hydraulic power converter). 9. Mechanics of fluids (steady flow in a pipe for an ideal fluid, law of continuity, Bernoulli's equation). 10. Momentum theorem. Stationary flow in a pipe for viscous fluid. Task. 11. Basic knowledge of thermodynamics (basic concepts, heat conduction, convection, heat transfer). 12. Flow machines (pumps, fans). 13. Caloric machines (domestic refrigerators).

Requirements, evaluation and grading

Mid-term study requirements

During the semester, we check the acquired level of knowledge by writing 2 pieces of 50-50 points written examination papers. If the scores of the booth examinations do not reach 50% of the maximum available score (minimum 25-25 points), we will give opportunity to write an 100-point extra written examination paper. Conditions for admission to the exam: At least 50% of the written examinations (at least 50 points) or the extra written examination must be at least 50 points.

Exam requirements

The exam consists of a written and an oral part. For the written part of the examination, the results of the written examination papers or supplementary examination papers written during the semester of the course will be accepted upon request. In the oral examination, one mark may be added to the written result. Candidates who only sit an examination will be assessed on the basis of an oral examination if they achieve a maximum of a medium mark, otherwise a written examination will be required. In the oral test, a pass mark is awarded for each major part of the material.

Generative AI usage

1st position: Use of GAI tools is not permitted for solving assignments. This means GAI tools cannot be used to complete formative or summative assessments, and using GAI constitutes academic misconduct. The use of AI tools for spelling and grammar checking does not fall under this prohibition.
