For glass on glass 0 4.
The static and kinetic friction coefficient values reference table shown in this article will be helpful for finding the cof values of commonly used materials.
The friction force can be calculated as.
The making of steel involves many processes and stages.
Static friction is friction between two or more solid objects that are not moving relative to each other.
Coefficients of friction between materials are best determined through testing.
The coefficient of static friction typically denoted as μ s is usually higher than the coefficient of kinetic friction.
Showing the concept of coefficient of friction.
The friction coefficient between the object and the surface is 0 62.
The coefficient of static friction for steel is around 0 6 0 15 and the coefficient of kinetic friction is around 0 09 0 6.
The value of μ s is generally higher than the value of μ k for a given combination of materials.
