Ebook: Engineering Mechanics Dynamics 15th Edition

Engineering mechanics is the study of the state of rest or motion of
bodies subjected to the action of forces. It is divided into two areas,
namely, statics and dynamics. Statics is concerned with the equilibrium
of a body that is either at rest or moves with constant velocity. Here
we will consider dynamics, which deals with the accelerated motion of
a body. This subject will be presented in two parts: kinematics, which
treats only the geometric aspects of the motion, and kinetics, which is
the analysis of the forces causing the motion. To develop these principles,
the dynamics of a particle will be discussed first, followed by topics in
rigid-body dynamics in two and then three dimensions.
