Learning objectives
On the basis of a deep knowledge of kinematics, statics and dynamics of mechanical system, the course provides the practical and theorical knowledge required for a proper functional design of machines and their devices
Prerequisites

Teaching methods
Lessons and exercises with applied examples of topics which are discussed at the lessons.
NOTE: In case the pandemic emergency has not been resolved, lessons will be given in teleconference via Teams platform. Lessons on Teams will be also interactive, and presentations will be stored on the Elly platform.
Assessment methods and criteria
The exam consists in a written examination about topics teached during the lessons. Duration: 1h:20'.
NOTE: In case the pandemic emergence has not been resolved, the exam will be given via teleconference via Teams, and instructions will be communicated via email when the student applies for the exam.
