# Vector Mechanics for Engineers: Statics, 8th Edition

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, designed for the first course in statics offered in the sophomore year, and the vol­ume that follows, Vector Mechanics for Engineers: Dynamics, will help the instructor achieve this goal.

Vector analysis is introduced early in the text and is used in the pre­sentation and discussion of the fundamental principles of mechanics. Vector methods are also used to solve many problems, particularly three-dimensional problems where these techniques result in a sim­pler and more concise solution. The emphasis in this text, however, remains on the correct understanding of the principles of mechanics and on their application to the solution of engineering problems, and vector analysis is presented chiefly as a convenient tool.

Practical Applications Are Introduced Early. One of the characteristics of the approach used in these volumes is that me­chanics of particles is clearly separated from the mechanics of rigid bodies. This approach makes it possible to consider simple practical applications at an early stage and to postpone the introduction of the more difficult concepts. For example:

• In Statics, statics of particles is treated first (Chap. 2); after the rules of addition and subtraction of vectors are introduced, the principle of equilibrium of a particle is immediately applied to practical situations involving only concurrent forces. The statics of rigid bodies is considered 111 Chaps. 3 and 4. In Chap. 3, the vector and scalar products of two vectors are introduced and used to define the moment of a force about a point and about an axis, The presentation of these new concepts is followed by a thorough and rigorous discussion of equivalent systems of forces leading, in Chap. 4. to many practical applications invoking the equilib­rium of rigid bodies under general force systems.
