3. Basic theory
Concept
strain : Against an external force with the fact that against the unit area it shows the internal resistance which the object shows, to the external force which operates to the object there is two branch type. Low me in the surface force, gravitational pressure or from the object whose one object is different with the pressure which it receives together the force which operates to the surface of the object and, also different low I with deposit power, with gravity or magnetism together am the force which operates the inside the object. Consequently the stress when it defines strictly, with afterwords is same.

stress : When the external force operates to the object, the form changes and and the fact that this variation at unit length it shows is strain. With the picture lower part the initial point for distance which it indicates together in the specimen increased by as external force, when it does, strain.
