Fluid Behavior Under Force
Description
Fluid behavior under force differs from the behavior of solids. When a force acts parallel to the top surface of a solid, the solid resists it because of internal friction between its layers. This is called shearing resistance. If the force is removed, the shearing forces help the solid return to its original shape.

The study of rigid bodies is limited to solids, as liquids and gases do not have a definite shape and conform to the available space around them. Because of this, they are collectively called fluids.
Forces applied tangentially to a surface are called shearing forces. Solids resist shearing forces, but fluids deform continuously when a sh...
