elastic properties of solids

Applications of Elasticity - Mechanical properties like strength, stiffness (Rigidity), ductility, malleability and brittleness have to be carefully studied to select a material for a particular job. The metallic parts of machines should not be subjected to stress beyond the ..

External forces acting on a body, bring about a change in its state or configuration. The latter is possible when the body is not free to move, but the molecules are compelled to change their positions. Such forces are called deforming forces. These forces bring about a change in the length, volume..

It is defined as the ratio of normal stress to the volumetric strain within the elastic limit. Thus, Consider a spherical solid body of volume V and surface area a, when a force F is applied normally, the volume decreases by ..

Insulators do not conduct electricity because the electrons present in them are held tightly to the individual atoms or ions and are not free to move. However when electric field is applied polarization takes place because the nucleus is attracted towards cathode and electron cloud towards anode. f..

The magnetic properties of materials are a consequences of magnetic moments associated will individual electrons. The magnetic moment of an electron is due to its orbital motion and also due to its spin around its own axi..

1) Ammonium sulphate is a colourless crystalline solid. 2) It is soluble in water to a great extent. The solubility of this salt in water is 78 g at 30 o C. 3) When dissolved in water it absorbs heat and causes coolin..
