This article gives you a summary of Elasticity and types of materials, you will also learn the Hooke’s Law, read more on stress and strain and its formula likewise the Young Modulus, longitudinal stress and strain and finally, the\u00a0modulus of elasticity.<\/p>\n
Elasticity, This is the ability of a material to regain its original shape and size after been distorted by an external force.<\/p>\n
It is\/they are materials that return to its original shape and size after distorting force has been removed or after deformation.<\/p>\n
<\/span><\/p>\n It is\/they are materials that do not return to its original shape and size after deformation.<\/p>\n HOOKE’S LAW<\/strong><\/p>\n It states that provided that the elastic unit of an elastic material is not exceeded the extension “e” of the material is directly proportional to the load or applied force “f”.<\/p>\n Formula: F= -KE<\/p>\n To find the spring constant; K = F \u00f7 Change in length.<\/p>\n It is the ratio of applied force “F” to the area “A” over which it acts.<\/p>\n Stress = Force \u00f7 Area<\/p>\n Unit for stress is “Pa”<\/p>\n It is the relative change in dimension or shape of a body as the result of applied stress.<\/p>\n Strain = change in length \u00f7 original length.<\/p>\n For wire, rod, and bar there is longitudinal stress that produces a change in length per unit length.<\/p>\n <\/span><\/p>\n It is the maximum stress a body can experience without being permanently deformed<\/p>\n NB: If the stress exceeds the ultimate strength, the material break.<\/p>\n Provided that the elastic limit is not exceeded and elastic deformation (strain) is directly proportional to the magnitude of the applied force per unit area.<\/p>\n Formula = stress \u00f7 strain.<\/p>\n For materials whose length is much greater than the width or thickness, we are concerned with the longitudinal modulus of elasticity.<\/p>\n Y= stress \u00f7 strain = F\/A \u00f7 change in length divided by<\/strong> the original length.<\/p>","protected":false},"excerpt":{"rendered":" Dit artikel geeft je een overzicht van Elasticiteit en materiaalsoorten, je leert ook de Wet van Hooke, leest meer over spanning en rek en de ...<\/p>\nInelastic Material<\/h3>\n
