| Contents | The course of "Machine Design" is proposed to apply the methods of structural design to machines and components. In this module some general issues relating to the strength of mechanical components under static and cyclic conditions will be studied. |
| Reference texts | R.C. Juvinall, K.M. Marshek, "Fondamenti della Progettazione dei componenti delle macchine", Edizioni ETS, Pisa 1993 |
| Educational objectives | The student must demonstrate that to have the knowledge necessary to develop the structural design of machines and their components, in relation to stresses and environmental operating situations. In particular, it will have to demonstrate knowledge and ability to apply mechanical strength evaluation techniques under static and cyclic stresses. In addition to the knowledge of the main types of machine elements, it will be necessary to demonstrate and know how to apply the calculation procedures of some of the major components of the machines and link elements. |
| Prerequisites | It is requested to pass the exam of "Scienza delle Costruzioni" |
