OVERVIEW
The course aims to provide the student with the basic elements of rational mechanics with particular reference to the mechanics of the rigid body and its applications to engineering.
AIMS AND CONTENT
LEARNING OUTCOMES
The course provides the mathematical methods for describing mechanical systems. In particular the motion of systems with many degrees of freedom is studied the rigid body mechanics analyzed in details.
AIMS AND LEARNING OUTCOMES
After the course completion the student is familiar with the statics and the dynamics of mechanical systems with finite degrees of freedom (particles systems and systems composed by rigid bodies).
PREREQUISITES
mathematical calculus, basic linear algebra, mathematical analysis I, Physics I.
TEACHING METHODS
The course includes lectures at the blackboard in which the topics of the program are presented. Examples and exercises, designed to clarify and illustrate the concepts of the theory, are also carried out.

EXAM DESCRIPTION
The exam consists of a written and an oral exam. The student must pass the written test and, after, he can access to the oral exam.
The written exam lasts three hours and consists of two problems on the subjects covered in class. The first problem is about the determination of barycenters and inertia tensors. The secondo problem is about the determination of the equations of motion of a constrained rigid body.
The oral examinations consists of three questions on the topics of the course.
Both during the written exam and during the oral exam, it is not possible to consult anything or use the calculator (except for the exceptions foreseen for students with DSA).
To participate in any type of test, students must register on the website.
ASSESSMENT METHODS
The written test verifies that the student knows how to set and solve problems of kinematics and dynamics of material systems and in particular of mechanics of the constrained rigid body.
The oral test verifies that the student has overcome any gaps that emerged in the written test and has acquired the theoretical technical skills.The quality of the presentation, the correct use of the specialized lexicon and the critical reasoning skills contribute to the final evaluation.
