Learning Objectives

The student will acquire the basics for the understanding of classical mechanics, wave phenomena, fluid mechanics, thermal phenomena. Moreover, through exercises and problems to be solved in the classroom and at home, the student will be accustomed to solving concrete problems. The student who will have acquired the topics and methodologies of the course, will be able to face and solve problems of various kinds through a logical-scientific approach. In particular, the course proposes the following objectives:

Course Structure

Theory lessons and resolutions of issues and problems in the classroom. Final evaluation based on written and oral exam.

PLEASE NOTE: Should the circumstances require online or blended teaching, appropriate modifications to what is hereby stated may be introduced, in order to achieve the main objectives of the course. Moreover the exams may take place online, depending on circumstances.
