PREFACE
Part III: Elastic and Fluid Media
In the early 1950's the option structure was abandoned and mon core
curriculum was instituted for all electrical engineering students at .
The objective of the core curriculum was then, and is now, to provide a
foundation in mathematics and science on which a student can build in his
professional growth, regardless of the many opportunities in electrical
engineering from which he may choose. In meeting this objective, core
curriculum subjects cannot serve the needs of any professional area with
respect to nomenclature, techniques, and problems unique to that area.
es in elective subjects, graduate study, and professional
activities.
To be effective a core curriculum subject must be broad enough to be
germane to the many directions an electrical engineer may go professionally,
yet it must have adequate depth to be of lasting value. At the same time, the
subject must be related to the real world by examples of application. This
is true because students learn by seeing material in a familiar context, and
engineering students are motivated largely by the relevance of the material
to the realities of the world around them.
In anization of the core curriculum in electrical engineering at
. electromechanics is one ponent. As our core curriculum
has evolved, there have been changes in emphasis and a broadening of the
topic. The basic text in electromechanics until 1954, when
