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 coefficient of static friction for steel is around 0 6 0 15 and the coefficient of kinetic friction is around 0 09 0 6. For polished oiled metal surfaces less than 0 1. For example static friction can prevent an object from sliding down a sloped surface. Coefficients of friction between materials are best determined through testing.

The value of μ s is generally higher than the value of μ k for a given combination of materials. The basic raw materials are coal iron ore limestone and various chemicals. F f 0 62 100 lb 62 lb 1 lb 0 4536 kg. Typical values for the coefficient of friction when sliding is occurring i e.

The coefficient of static friction typically denoted as μ s is usually higher than the coefficient of kinetic friction. The friction force can be calculated as. Static and kinetic coefficient of friction. 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.

However it is possible to find tables in the literature for friction coefficients between various materials. Example car braking friction force and required distance to stop. For glass on glass 0 4. The making of steel involves many processes and stages.

The dynamic coefficient of friction are. For rubber on tarmac close to 1 0. The coefficient of friction is the ratio of a force to a force and hence has no units. A car with mass 2000 kg drives with speed 100 km h on a wet road with friction coefficient 0 2.

Static friction is friction between two or more solid objects that are not moving relative to each other.
