The objective for the current chapter is to investigate the effects of forces on particles: replacing multiple forces acting on a particle with a single equivalent or resultant force, relations between forces acting on a particle that is in a state of equilibrium. | Ninth Edition VECTOR MECHANICS FOR ENGINEERS STATICS CHAPTER Beer hnston Jr. Ferdinand P.

The focus on particles does not imply a restriction to miniscule bodies. Rather the study is restricted to analyses in which the size and shape of the bodies is not significant so that all forces may be assumed to be applied at a single point. 2 -
