"Mechanics can be defined as that branch of the physical sciences concerned with the state of rest or motion of bodies that are subjected to the action of forces. In general, this subject is subdivided into three branches: rigid-body mechanics, deformable-body mechanics, and fluid mechanics... 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 constant velocity; whereas dynamics is concerned with the accelerated motion of bodies. Although statics can be considered as a special case of dynamics, in which the acceleration is zero, statics deserves separate treatment in engineering education since many objects are designed with the intention that they remain in equilibrium." p 3

PARTICLE
AN OBJECT WITH VERY SMALL DIMENSIONS COMPARED TO ANY OTHER SYSTEM PARAMETER. ONE CAN THINK OF A PARTICLE AS LOCATED AT A POINT IN SPACE AND IGNORE ANY EFFECTS CAUSED BY THE FINITE SIZE OF THE OBJECT.

RIGID BODY
AN OBJECT IN WHICH ALL THE COMPONENT PARTS REMAIN FIXED IN POSITION RELATIVE TO EACH OTHER.
