(BQ) The book "Engineering mechanics - Statics" technologically advanced online tutorial and homework system available, can be packaged with this edition. This book is ideal for civil and mechanical engineering professionals. | R. c. HIBBELER The design of this rocket and gantry structure requires a basic knowledge of both statics and dynamics which form the subject matter of engineering mechanics. General Principles CHAPTER OBJECTIVES To provide an introduction to the basic quantities and idealizations of mechanics. To give a statement of Newton s Laws of Motion and Gravitation. To review the principles for applying the SI system of units. To examine the standard procedures for performing numerical calculations. To present a general guide for solving problems. Mechanics Mechanics is a branch of the physical sciences that is concerned with the state of rest or motion of bodies that are subjected to the action of forces. In general this subject can be subdivided into three branches rigid-body mechanics deformable-body mechanics and fluid mechanics. In this book we will study rigid-body mechanics since it is a basic requirement for the study of the mechanics of deformable bodies and the mechanics of fluids. Furthermore rigid-body mechanics is essential for the design and analysis of many types of structural members mechanical components or electrical devices encountered in engineering. Rigid-body mechanics is divided into two areas statics and dynamics. Statics deals with the equilibrium of bodies that is. those that are either at rest or move with a constant velocity whereas dynamics is concerned with the accelerated motion of bodies. We can consider statics as a special case of dynamics in which the acceleration is zero however statics deserves separate treatment in engineering education since many objects are designed with the intention that they remain in .
