In this article, we have described briefly the different types of frictional resistances such as dry friction, fluid friction and internal friction encountered ..
The sliding of a solid body in contact with another solid body is always opposed by force of friction. Friction acts in the direction opposite to that of relative ..
Coefficient of Friction The coefficient of friction (μ), is a measure of the amount of friction existing between two surfaces. A low value of the coefficient ..
In fluid dynamics, the pipe flow equation most commonly used is the Darcy-Weisbach equation that prescribes the head loss hf to be: Where ‘L’ is the pipe ..
In a sliding joint, contact force always acts perpendicular to the surface in contact. This contact force is commonly referred to as a normal force because it acts ..
