CA2: Applying knowledge and understanding related to the analysis and optimization of mechanical devices and systems, as well as to their innovation also through the development and improvement of design methods, constantly confronting with the rapid evolution of mechanical engineering.
CA4: Applying knowledge and understanding related to the implementation of engineering projects adapted to their level of knowledge and understanding, working in collaboration with engineers and non-engineers. The projects may concern components, equipment and mechanical systems of various kinds and for the widest possible applications.
CA12: Applying adequate knowledge and understanding to understand English texts.
CA15: Applying knowledge and understanding to achieve adequate preparation for tertiary level university studies (frequency to post-master's degree courses and doctoral schools) in order to further deepen knowledge and skills in research.
CC1: In-depth knowledge and understanding of the theoretical-scientific aspects of engineering, with a specific reference to mechanical engineering, in which students are able to identify, formulate and solve, even in an innovative way, complex and/or interdisciplinary problems. The ability to understand a multidisciplinary context in the engineering field and to work with a problem solving approach

The competences regarding the mechanics of the vehicle are considered as preparatory.

Lectures

Oral exam.
The questions are aimed at verifying the knowledge of the field of land vehicles by analyzing the structural aspects of the various types of vehicles and verifying the understanding of the engineering context and the interdisciplinary implications that characterize the land vehicle sector.
The student must demonstrate that he has acquired the knowledge of the field of land vehicles by analyzing the structural aspects of the various types of vehicles and the understanding of the engineering context and the interdisciplinary implications that distinguish the land vehicle sector.
