Learning outcomes
Knowledge
The student who successfully completes the course will have the essential knowledge of lubrication and its application to machines and systems. The student will be able to realize a correct tribological design in order to spare materials and energy. He/she will have the ability to verify the operating conditions of lubricated pairs, such as bearings and gears.
Assessment criteria of knowledge
During the oral exam the student must be able to demonstrate his/her knowledge of the course material and to solve verification and design problems.
