Surface force denoted fs is the force that acts across an internal or external surface element in a material body.
cohesive forces and contact forces
between objects are considered as surface forces.
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 ,[1] and area is a ,
- a pressure of over an area of will produce a surface force of .
