Surface force
This article does not cite any sources. (January 2013) |
Surface force denoted fs is the force that acts across an internal or external surface element in a material body. Surface force can be decomposed into two perpendicular components: normal forces and shear forces. A normal force acts normally over an area and a shear force acts tangentially over an area.
Equations for surface force[]
Surface force due to pressure[]
- , where f = force, p = pressure, and A = area on which a uniform pressure acts
Examples[]
[]
Since pressure is , and area is a ,
- a pressure of over an area of will produce a surface force of .
