General Principles 1 CHAPTER OBJECTIVES ·To provide an introduction to the basic quantities and idealizations of mechanics. 0 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. 1.1 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 ponents,or electrical dev...
