According to Hooke's law within the elastic limit (stress)/(strai n)= constant. The constant depends on the type of strain or the type of force acting. Tensile stress might result In compressional or elongative strain, however, a tangential stress can only cause a shearing strain. After crossing the elastic limit. the material undergoes elongation and beyond a stage beaks. All modulus of elastically are basically constants for the materials under stress If (stress)/(strai n) is x in elastic region and y in yield region, then
