coefficient of friction, ratio of the frictional force resisting the motion of two surfaces in contact to the normal force pressing the two surfaces together . It is usually symbolized by the Greek letter mu (μ). Mathematically, μ = F/N, where F is the frictional force and N is the normal force.
A coefficient of friction is a value that shows the relationship between two objects and the normal reaction between the objects that are involved. |
The coefficient of friction is the ratio of the tangential and the normal forces. The friction factor is the ratio of the friction stress and the yield strength ... |
The coefficient of friction (fr) is a number that is the ratio of the resistive force of friction (Fr) divided by the normal or perpendicular force (N) pushing ... |
