Body force vs surface force
WebSurface forces act on each surface element of the body and these are exerted when the body will be kept in direct mechanical contact with … WebThe more that surface molecules tend to adhere to each other, the greater the coefficient values and the greater the friction force. Friction forces can also exist when the two …

WebTherefore, the total force is proportional to the volume of fluid. We define f~ to be the ”body force” acting on a unit volume, then the ”body force” on a given mass ρdV is … WebMay 13, 2024 · For a solid body immersed in a fluid, the "point of contact" is every point on the surface of the body. The fluid can flow around the body and maintain physical contact at all points. The transmission, or application, of mechanical forces between a solid body and a fluid occurs at every point on the surface of the body.
WebJul 28, 2024 · Surface forces are distributed forces where the point of application is an area (a surface on the body). Body forces are forces where the point of application is a volume (the force is exerted on all molecules throughout the body). Below are some examples of surface and body forces.
