Planned learning activities and teaching methods
Lectures are based on Shigley: Mechanical Engineering design. In tutorials is solved the project Design of the gearbox and sw Mathcad or MS Office Excel is used.
Assesment methods and criteria linked to learning outcomes
-activity in tutorials, written solution of semestral project, its oral presentation (maximal number of points is 40, minimal number of points necessary for course-unit credit is 20).
Examination requirements:
-electronic testing system. Test with possibility of answers selection is based on lectures and tutorial topics (maximal number of points obtained from test is 60, minimal number of points for passing the test is 30.) The textbook "Mechanical Engineering Design" is allowed.
Total number of points is sum of points obtained from semestral project and points obtained from exam test. Minimal number of points is 50 and maximal number of points is 100. Resulting classification is made according ECTS.

Aims
Specification of controlled education, way of implementation and compensation for absences
Lectures based on the textbook Mechanical Engineering Design are not available in Moodle system. This textbook is fundamental for preparation to exam.
Ihe teamwork project "Design of the gearbox" is solved in tutorials. The student must have the textbook "Mechanical Engineering Design". For project elaboration computers or own notebooks with Mathcad or MS Office Excel can be used.
