Vector Mechanics for Engineers: Statics and Dynamics, 12th Edition – Ferdinand P. Beer

A primary objective in a first course in mechanics is to help develop a stu­dent’s ability first to analyze problems in a simple and logical manner, and then to apply basic principles to their solutions. A strong conceptual under­standing of these basic mechanics principles is essential for successfully solving mechanics problems. We hope this text will help instructors achieve these goals.

General Approach

Vector algebra is introduced at the beginning of the Statics volume and is 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 is introduced early in the Dynamics volume, and vector analysis is used throughout the presentation of dynamics. This approach leads to more concise derivations of the fundamental principles of mechanics. It also makes it possible to analyze many problems in kinematics and kinetics which could not be solved by scalar methods. 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 this book 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, the statics of particles is treated first, and the principle of equilibrium of a particle is immediately applied to practical situations involving only concurrent forces. The statics of rigid bodies is consid­ered later, at which time 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.
  • In Dynamics, the same division is observed. The basic concepts of force, mass, and acceleration, of work and energy, and of impulse and momentum are introduced and first applied to problems involving only particles. Thus, students can familiarize themselves with the three basic methods used in dynamics and learn their respective advan­tages before facing the difficulties associated with the motion of rigid bodies.

Muy elegante. ¿Alguien tiene el Instructor Solutions Manual?
