INTRODUCTION

Mechanics can be divided into three parts, such as mechanics of rigid body, mechanics of solids and mechanics of fluids. In mechanics of rigid body, it is assumed that there is no internal deformation in the body and we study about the static and dynamic position of the body subjected to external forces. In mechanics of solid, it is assumed that the solid deforms subjected to external forces and we study about the nature of deformation in the body. In fluid mechanics, shape and size of the body is not constant and we study about statics and dynamics of flow of fluid subjected to various types of forces on it.
