materials in strenght

  STRENGHT IN MATERIALS

 Materials can be classificate according to their shape,colour,flexibility,strenght,specific gravity. All of these properties has its own importance for the treatment of a material. Strenght is a property that show how materials behave in stresses and strains.Copressive stress is that stress that two forces act inverse to the center of the object  so to study how the material behave in compression.Another stress  is tensile stress that two forces act contrary so  to study how the materials behave in load.The last stress that is used for the study of a material in strenght is shear stress that two forces act  contrary at the two faces of the material.The type that scientits use for these studies of materials in strength is σ=F/A where stress is "σ"(count in N/m^2), "F" is the force that act to the material(count in Newton) and "A" which is the area of the object(count in m^2).In the end of these studies ,materials classificiate is subcategories which show where the materilas has its highest strenght and these categories are yield strenght,compressive strenght,tensile strenght ,fatique strenght, impact strenght and elacticity.In my opinion strenght studies in materials  are very important for the safety of the new products because if a product with materials of   low strenght will be used in the manufacturing of cars ,builduing and generally in our everyday life  means that in a few years after can cost human lives .
