INTRODUCTION OF ENGINEERING MECHANICS

PARTICLE

                        It is a body of infinite small dimensions may be considered as a point only having the existence

                       For the shake of analysis, a body may be considered as a particle.

RIGID BODY

                       This is define as the body having no deformation or do not change it’s shape and size ,called rigid body

                       In practical , no body is perfectly rigid body , but for the shake of analysis we can take a body as rigid body.

DEFORMABLE BODY

                       This is define as the body having no deformation or changes it’s shape and size under the action of forces called deformable body.

                       In practical , all the bodies in this universe are deformable body.
