Three-Dimensional Force Systems 1/7 Rectangular Components 1/8 Moment and Couple 1/9 Resultants Chapter Review 1/1 INTRODUCTION In this and the following chapters, we study the effects of forces which act on engineering structures and mechanisms. The experience gained here will help you in the study of mechanics and in other subjects such as stress analysis, design of structures and machines, and fluid flow. This chapter lays the foundation for a basic understanding not only of statics but also of the entire subject of mechanics, and you should master this material thoroughly. 1/2 FORCE Before dealing with a group or system of forces, it is necessary to examine the
