Value Of Coefficient Of Friction Between Steel And Rubber

For glass on glass 0 4.

Value of coefficient of friction between steel and rubber. 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 two main frictions used are static friction and kinetic friction. The value of μ s is generally higher than the value of μ k for a given combination of materials.

Where μ s is the coefficient of static friction and μ k is the coefficient of kinetic friction. Showing the concept of coefficient of friction. The friction coefficient between the object and the surface is 0 62. Static and kinetic coefficient of friction.

The dynamic coefficient of friction are. Example car braking friction force and required distance to stop. Coefficients of friction between materials are best determined through testing. The making of steel involves many processes and stages.

The friction force can be calculated as. For polished oiled metal surfaces less than 0 1. 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. For rubber on tarmac close to 1 0.

The basic raw materials are coal iron ore limestone and various chemicals. Typical values for the coefficient of friction when sliding is occurring i e. F f 0 62 100 lb 62 lb 1 lb 0 4536 kg. 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.

However it is possible to find tables in the literature for friction coefficients between various materials.
