20810127 - THEORETICAL MECHANICS

The primary aim of the course is to provide to the students the skills to formalize a problem of rigid-bodies mechanics using the appropriate mathematical tools. Particular attention is paid on the modeling and analysis of simple engineering problems, in order to provide the cultural background required to cope with engineering analysis and design.
