Modalité de ensegnament
The topics are presented by the professor by means of Power Point presentations or the blackboard. A selection of the material presented in class as well as online resources and useful material will be available in the OLE database/. Further deepening material will be supplied or recommended by the teacher.

Obietifs formatifs
Knowledge and understanding: 1) Handle the analysis methods used in structural design of mechanical systems. Applying knowledge and understanding: 2) Know how to face a new project of a mechanical system starting from its functional design. Making judgements: 3) Identify the critical zones and the corresponding stress states of all components of a mechanical system, under service loading conditions. 4) Choose the geometry and materials able to satisfy the requirements of each component in terms of strength, deformation, fatigue life, and so on and realize the technical drawing of the system.
