Resonance: A Unique Phenomenon, but with Many Manifestations

Abstract

The widespread habit, of our courses as well as texts and professors, it is to treat the diverse manifestations of this interesting phenomenon as if they were problems or different situations, without anything or with very little that to see to each other.This way, when it is treated in Mechanics (inside the forced oscillations); in Electromagnetism (inside the circuits RLC, of CA); in the effect MÖSSBAUER and in other scientific branches of the knowledge, concepts, neither general approaches of the same one are not given but strictly local (and even more, in occasions, investing the order of what can be called their cause and their consequence more important).This work has as objectives: to settle down with clarity a generic concept of the problem, applicable then to the most diverse local conditions. It is also to demonstrate and to convince of the validity, and utility, of such a position, with two examples of the simplest of our courses, one in Mechanics and the other one in Electromagnetism. As well as to propitiate the discussion of the educational ones in this respect, and the critical prosecution that allows to come closer to a more appropriate focus, and unifier, of this phenome-non.
