CC3
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.
CC4
Knowledge and understanding of thermodynamics applied to energy systems and of fluid-dynamic phenomena as well as models capable of representing them. Knowledge of systems and machines for the production and conversion of energy, with particular reference to turbomachinery and industrial combustion equipment. Understanding the role of different energy technologies in ensuring the environmental and economic sustainability of production.
CA3
Applying knowledge and understanding related to the most appropriate methods of analysis, modelling, verification and experimentation to design, analyze and test machines and plants. This includes: the interpretation and drafting of mechanical parts and machines (also using dedicated CAD systems); the sizing and the functional and structural verification of components and mechanical groups subjected to static and fatigue stress; the functional setting of the design of a mechanical system, applying the principles of kinematics and static principles; analysis of the characteristics of metallic and polymeric materials for the production; the choice of the best production process aimed at the creation of mechanical components; analysis and design of production systems including the study of reliability, safety and economic and environmental sustainability.
CA4
Applying knowledge and understanding related to analytical modelling and experimental methods to design, analyze and test fluid machines, thermal motors and energy conversion systems. This includes: the application of design criteria for technical and thermos-technical plants, fluid and energy distribution; the application of thermodynamic principles to simple systems; the understanding of the main thermodynamic cycles and the reading of thermal diagrams; the identification of significant heat transmission mechanisms for engineering applications; the analysis and functional design of equipment of mechanical interest such as turbomachinery, energy conversion systems and internal combustion engines; the evaluation of the energy, economic and environmental performance of fluid, thermal and oleo-dynamic machinery
In details the focus is: knowledge and skills in the field of experimentation, measurement and testing on machines, structures and products and industrial processes. In particular, the course aims to provide knowledge on:
- meaning of measurement, experimentation and testing. Static and dynamic measurements;
- sensors, main physical principles used and measuring chains for different types of measurement;
- data analysis and processing, taking into account measurement errors and uncertainties;

Through examples and case studies, the course also aims to increase the ability to apply the knowledge listed above, in particular:
-to identify the most suitable methods for carrying out experimentation or control on a product / structure / machinery and to assess / verify / test its characteristics.

-to understand how performance can be verified and systems can be improved, , innovating the systems also through the development and improvement of measurement and control methods, in the field of mechanical engineering.

A further objective is to achieve an adequate preparation to achieve an adequate preparation to access the third level of university studies (attendance at second level master and doctoral schools), in order to further deepen knowledge and skills in the field of research.

solid foundations of physics, mathematics analysis, technical physics and machine design.

The course is primarily addressed through lectures with some lab experience to better understand the use of advanced tools.

the experimental approach, even if tiring, allows to familiarize with sensors and acquisition and control systems, finalizing the theoretical concepts.

CT1-Written technical communication (reports, deliverables)
CT2-Coordinated work group
CT3-Development of an adequate expression and technical discussion of own arguments
CT4-Graphic representation and communication (drafting of diagrams, graphs and tables)
CT5-Understanding of technical standards
CT6-Conducting bibliographic research using the main resources (libraries, scientific databases, etc.)
CT7-To respect commitments and deadlines
CT8-Communication through presentations and web systemsFurthermore on a voluntary basis, a measurement experience in the laboratory with the related report can be done, to be carried out normally in groups.
In this case the report will be discussed during a final oral examination, which is divided into the following parts:
1) presentation and discussion of the eventual report (ten-fifteen minutes)
2) standard oral exam (25-30 minutes ) with two "" theoretical "questions taken from the program, or an application question, on the testing of a system or a system component.
The total duration of the oral exam is about 30-40 minutes

basic concepts on measurement and measurement systems.
Measurement systems and main components, connections and measuring chain.
Characteristics of the instruments. Constant and variable signals over time. Errors; errors
definition, identification and propagation in the measurement chain .
Temperature measurements; seebek effect and thermocouples, thermocouple laws, thermoresistance and thermistors.

the course contributes to the finalization of the UN objectives of the 2030 Agenda for Sustainable Development
