Value Of Coefficient Of Friction Between Steel And Rubber

Where μ s is the coefficient of static friction and μ k is the coefficient of kinetic friction.

Value of coefficient of friction between steel and rubber.

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 value of μ s is generally higher than the value of μ k for a given combination of materials. The friction force can be calculated as. For example static friction can prevent an object from sliding down a sloped surface.

Example car braking friction force and required distance to stop. Showing the concept of coefficient of friction. The making of steel involves many processes and stages. The two main frictions used are static friction and kinetic friction.

However it is possible to find tables in the literature for friction coefficients between various materials. Static and kinetic coefficient of friction. Typical values for the coefficient of friction when sliding is occurring i e. The friction coefficient between the object and the surface is 0 62.

For glass on glass 0 4. Coefficients of friction between materials are best determined through testing. For polished oiled metal surfaces less than 0 1. For rubber on tarmac close to 1 0.

Static friction is friction between two or more solid objects that are not moving relative to each other. A car with mass 2000 kg drives with speed 100 km h on a wet road with friction coefficient 0 2. 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 coefficient of friction is the ratio of a force to a force and hence has no units.

The dynamic coefficient of friction are.
