RATIONAL MECHANICS

Course objectives

General learning outcomes The class in Meccanica Razionale has a twofold aim: provide the students with the methods necessary to approach the study of constrained mechanical systems, in particular rigid body systems, and show how a rigorous mathematical formalism can be fully integrated within a physical theory enabling its full and deep rigorous understanding. Specific learning outcomes Knowledge and understanding skill The students learn the theory of Euclidean spaces motion (relative motion), the kinematics and the dynamics of systems of rigid bodies, the Lagrangian approach to the study of ideal holonomic constrained systems. Moreover, the students will learn how to cast a mechanical problem in a mathematical model via the ordinary differential equation theory. Applying knowledge and understanding skill The class completed, the student will be able to deal with systems of rigid bodies and, in the case of ideal holonomic constraints, write the equation of motions sufficient to the description of all the possible motions of the system. Moreover, the student will have learnt the methods to detect the equilibrium position of the system and to study their stability character. Communication skill The students practice their communication skills during the final oral exam, in which they have to provide a mathematically rigorous treatment of relevant aspects of an involved physical theory. Learning skill The student practice his self-learning skills by tackling and solving many different physical problems. The student, indeed, has to attack a physical problem on his own trying, first, to recast the problem using the correct mathematical modelling and, then, studying analytically and qualitatively the equations he found.

Prerequisites
A basic knowledge of Classical Physics (in particular of Mechanics taught during the first academic year) is welcome while a thorough knowledge of Mathematics, with particular attention to Mathematical Analysis and Geometry is mandatory. Specifically, in order to understand the contents of the teaching and achieve the learning objectives, it is essential that the student has: 1. thorough knowledge of elementary algebra and affine and analytical geometry; 2. thorough knowledge of mathematical analysis (calculus); 3. rudimentary knowledge of mechanics.

Frequency
In person. Yet attending classes is voluntary and takes place in the classrooms and according to the schedule published by the Dean office. Attending classes, although warmly encouraged, does not contribute to the final mark.
Exam mode
The examination consists of the analytical solution of an exercise and, once this first written test has been passed, a short oral interview to also verify knowledge of the theory (oral test).
Lesson mode
Lessons will be given using a blackboard or a beamer.
