Course detail
Machine Design - Mechanical Drives
FSI-6KT-AAcad. year: 2014/2015
The aim of the course is to provide an overview of machine parts used for power and rotary motion transmission, such as gears, shaft couplings, brakes and flywheels. 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
1. Student activity in tutorials. Teachers discuss solutions with every member of the construction team during the semester. Every member of the team is responsible for different part of the project solution.
2. Elaboration and submission of semestral project on schedule set by the teacher. The complete project consists of: a) calculation report, b) drawing documentation of machine assembly, c) drawing documentation of machine parts selected by teacher.
3. The defense of semestral project through lecture, where every team member defends the topic which is responsible for. Lenght of the whole lecture is 10 minutes at maximum. If the student does not fulfill the requirements for the semestral project acceptance, he is entitled to have a maximum of one additional project defense. The date of defense is set by the teacher, usually during the examination period.
Final exam requirements: Multiple-choice test is performed on the computer and it utilizes the examination system of the Institute of Mechanical and Industrial Design. The test topics cover the problems mentioned in lectures and tutorials. Minimum score for passing the test is 30 out of 60 possible points. First part of the test (50%) consists of theoretical questions and second part (50%) consists of computational questions. The student has to pass the first (theoretical) part of the test to qualify himself to the second (computational) part. Each part of the final test is considered passed whether at least half of the questions are answered correctly. Each question has five answers, of which only one is correct. An incorrect answer does not mean negative point. A student card, pen and calculator are demanded to access the test room. The original print of the “Mechanical engineering design” textbook is allowed for the second part (computational) of the final test. Use of any other literature during the test is not allowed. The student which does not obtain the course credit is not allowed to attend the final exam.
The final score of the whole course consists of the total number of points earned from semestral project and multiple-choice test. The minimum required score is 50 points out of the maximum 100 points. The final score determines the grade according to ECTS.
