Limiting friction do not depend on area of contact surfaces but depends on their nature, i.e., smoothness or roughness. If angle of friction is θ, then coefficient of limiting friction μ s = tan θ 3.

WebThe friction now acting between the surfaces of contact is dynamic friction. The dynamic friction is always less than the limiting static friction. Dynamic friction is of two types: Sliding Friction; Rolling Friction; Sliding Friction: If one body begins to slides over the other, then the friction between the surfaces is called sliding friction.

Friction is the opposing force that is set up between the surfaces of contact when one body slides or rolls or tends to do so on the surface of another body. For example, if a book on a table slides from left to right along the surface of a table, a frictional force directed from the right to left acts on the book at the surface of ...
