Dynamics of Rigid Bodies
Objectives
The students that have successfully completed this curricular unit have demonstrated ability to:
-Understand the fundamental concepts and principles that form the basis of Kinematics and Dynamics of particles and rigid bodies;
-Apply the fundamental concepts and principles to analyze the kinematics of simple mechanisms, consisting of a limited number of rigid bodies;
-Apply the fundamental concepts and principles to analyze the dynamics of simple mechanisms, consisting of a limited number of rigid bodies;
-Understand and analyse the vibrations of undamped and damped rigid bodies and structures with one-degree-of-freedom.

Teaching method
All matters of discipline are covered in problem-solving sessions.
The exhibition and explanation of various concepts, principles and methods is exemplified with the resolution of some illustrative problems.
A discussion of the problems posed is promoted and students are encouraged to solve some problems individually.
