described by material models belonging to the class of yield stress fluids. So, how can yield stress fluids be dis-tinguished from classical materials – solids and liquids – in case of phenomenological modeling? This directly leads to the question of convenient classification crite-ria to separate solids, liquids and yield stress fluids from each other. The search for a definition of the

The properties of liquids are intermediate between those of gases and solids, but are more similar to solids. In contrast to intra molecular forces, such as the covalent bonds that hold atoms together in molecules and polyatomic ions, inter molecular forces hold molecules together in a liquid or solid.

Class XI _____ Chapter 10 – Mechanical Properties of Fluids force of attraction between themselves and a strong force of attraction toward solids. Hence, they tend to spread out. Surface tension is the force acting per unit length at the interface between the plane of a liquid and any other surface. This force is independent of the area of the liquid surface. Hence, surface tension is also

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into static friction (“stiction”) between non-moving surfaces, and kinetic friction between moving

Friction and its Types live_help Have a doubt, Ask our Like solids, fluids (liquids and gases) also exert pressure. A solid exerts pressure only in the downward direction due its weight, whereas liquids and gases exert pressure in all directions. Hence liquids and gases exert pressure on the walls of their container. Liquids exert equal pressure on all the sides of a container at the same
