Recommended books:

- E. Funaioli ed altri, "Meccanica applicata alle macchine", vol. I e II, Ed. Patron Bologna

1) Course's general purpose
To make the pupil aware of the operating principles of some mechanisms and mechanical applications through specific exercises. Understanding the functioning principles of the analyzed mechanisms. Overall sizing of the main mechanical systems.

2) Provided knowledge
Systematic knowledge and understanding of the key aspects of mechanical design of industrial engineering and its methods. In particular: understanding of which are the most suitable methods in order to define a product and its characteristics; knowledge of the technology of the materials that can be used, of the mechanical study of parts and assemblies, their dimensioning, their static and dynamic behaviour and interactions between components. The technologies for their production and their graphic representation are also areas of knowledge and understanding.

3) Applying knowledge
Applying knowledge and understanding problems related to identifying, formulating and solving industrial and specifically mechanical engineering problems, defining the specifications, technical, but also social, health and safety, environmental and commercial constraints, and resolving them using established methods, thus leading to engineering projects adapted to the level of knowledge and understanding developed. Projects may concern products, devices, machines, energy systems, automatic systems.

The lecturer assumes as acquired by the students the knowledge and competencies in phisics 1 (mechanics) and analytical dynamics

Lectures in the classroom

1) The student evaluation includes an oral examination on the exercises developed during the course. Questions are asked concerning, normally, one of the exercises developed

2) The student has to demonstrate at least basic knowledge of some of the most applicative aspects of the course of Theory of Machines and Mechanisms, and to be able in dimensioning some of the most classic mechanical applications

Exercises:
- Floating Drum (clasp brake) Brake System for Railways application
- Graphical kinematic analysis of Fairbairn's Guide
- Cam with circular-arc profiles: geometric and kinematic analysis
- Design of an Epicyclic gear train
- Design of a bi-stage belt drive system
- Sizing of a flywheel according to the Tredgold method
