Stress word is taken form Physics and introduced by Hans Sayle in 1936. It means some force is applied to the body to change its shape or deformation. It is purely a geometrical concept. It depends upon velocity, density, force and mass of the body. When stress is applied on body it distributed over whole body. This word is mainly used in physics, engineering and some part of mathematics. Stress concept is used on making of bridges, dams etc. Stress has two types according to direction of application of force. In case of fluid is called Shear stress. How small is the stress applied on the fluid it changes the shape of the body.

Stress, Strain, Force, Shear, tensile, normal, volumetric
