The main objective of a first course in mechanics should be to
develop in the engineering student the ability to analyze any
problem in a simple and logical manner and to apply to its
solution a few, well-understood, basic principles. It is hoped that
this text, as well as the preceding volume, Vector Mechanics for
Engineers: Statics, will help the instructor achieve this goal.t
Vector algebra was introduced at the beginning of the first
volume and used in the presentation of the basic principles of
statics, as well as in the solution of many problems, particularly
three-dimensional problems. Similarly, the concept of vector
differentiation will be introduced early in this volume, and vector
analysis will be used throughout the presentation of dynamics.
This approach results in a more concise derivation of the funda-
mental principles. It also makes it possible to analyze many
problems in kinematics and kinetics which could not be solved by
the standard scalar methods. The emphasis in this text, however,
remains on the correct understanding of the principles of me-
chanics and on their application to the solution of engineering
problems, and vector analysis is presented chiefly as a convenient
tool.~
