02EMPBK Experimental physiscs II 

1st degree and Bachelorlevel of the Bologna process in Automotive Engineering  Torino 





Objectives of the course
This course has the aim to complete tha basic knowledge discussed in Experimental physics I, focusing on engineering applications.
With lab experiences, this course teaches how to plan experiments, evaluate physical quantities, in order to represent and use them in engineering works. 
Expected skills
The student integrates the knowledge of Experimental physics I with electromagnetic phenomena.

Prerequisites
A good knowledge of differential and integral calculus for functions with many variables and vector calculus of Experimental physics I is
required.

Practical Work Programme Practicals are carried out in lecture halls with examples of topics studied. During the practicals are also discussed problems on a written report of lab activites. 
Laboratories and/or exercises
A second series of lab experiments are related to physical phenomena and interest of motor vehicle engineering is arranged.
 Strainflow features of different materials and devices.  Strenght measurement using Wheatstone's bridge.  Measurement of capacity and inductance using RLC circuits Tutorial Programme Professors are available to explain the students some topics of the program and of practicals, and to check, in an informal way, the learning of the students. Students are divided into two groups. Didactic Material Lecture Notes. E. Amaldi, R. Bizzarri, G. Pizzella FISICA GENEFALE, elettromagnetismo, relatività, ottica Zanichelli Editore M.
