OVERVIEW

The teaching provides the basic knowledge needed to understand the main physical and technical phenomena found in the design and production processes of industrial artefacts.

AIMS AND CONTENT

LEARNING OUTCOMES

The teaching provides an overview of Applied Physics. The aim is to allow the students in proceeding knowingly towards the solution of transdisciplinary problems, developing an educational path tailored to actual design problems. Problems related to heat and mass transfer, to hygrometry and elements on light sources and artificial lighting are dealt with.

AIMS AND LEARNING OUTCOMES

The teaching consists of both theoretical lessons and classroom exercises, aimed at applying the theory to specific problems. By the end of the course, the student will be able to set up and solve simple problems of mechanics, energy analysis of systems, fluid flow, transfer of heat by conduction, convection and / or thermal radiation.

TEACHING METHODS

As an integrative teaching activity, classroom exercises are given, aimed both at the application of the theoretical notions provided and at the deepening of some theoretical aspects.

EXAMS

EXAM DESCRIPTION

The exam consists of two mandatory parts: a written test and a subsequent oral test. The written test consists of a multiple-choice test, lasting one hour, on both theoretical and applicative topics. If the outcome of the written test is sufficient, the student is admitted to the oral test, which is also on theoretical and applicative topics. If the oral test is not sufficient, the exam is not passed and the written test must be repeated. Booking to the exam session is via the Unige portal.

ASSESSMENT METHODS

The written test evaluates the successful comprehension of the different topics of the course and the consequent ability to apply the concepts acquired to the solution of some simple problems.

The oral test allows to investigate with more accuracy the student's level of knowledge of the theoretical and applicative themes as well as his ability in performing critical reasoning. In the oral examination, attention is also paid to the clarity of the exposition and to the mastery of specific technical language.
