deformation. From equilibrium point of view, this action should be opposed or reacted by internal forces which are set up within the particles of material due to cohesion. These internal forces give a concept of stress. Therefore, let us define a stress. Let us consider a rectangular bar of some cross – sectional area and subjected to some
