Value Of Coefficient Of Friction Between Steel And Rubber

The coefficient of friction is the ratio of a force to a force and hence has no units.

Value of coefficient of friction between steel and rubber.

Example car braking friction force and required distance to stop. However it is possible to find tables in the literature for friction coefficients between various materials. For rubber on tarmac close to 1 0. The making of steel involves many processes and stages.

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 dynamic coefficient of friction are. Static and kinetic coefficient of friction.

The coefficient of static friction typically denoted as μ s is usually higher than the coefficient of kinetic friction. The two main frictions used are static friction and kinetic friction. For polished oiled metal surfaces less than 0 1. Typical values for the coefficient of friction when sliding is occurring i e.

The value of μ s is generally higher than the value of μ k for a given combination of materials. 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 friction coefficient between the object and the surface is 0 62. Showing the concept of coefficient of friction.

Coefficients of friction between materials are best determined through testing. The basic raw materials are coal iron ore limestone and various chemicals. A car with mass 2000 kg drives with speed 100 km h on a wet road with friction coefficient 0 2. F f 0 62 100 lb 62 lb 1 lb 0 4536 kg.

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