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.

Value of coefficient of friction between steel and rubber.

Typical values for the coefficient of friction when sliding is occurring i e. The two main frictions used are static friction and kinetic friction. The making of steel involves many processes and stages. The value of μ s is generally higher than the value of μ k for a given combination of materials.

The coefficient of friction is the ratio of a force to a force and hence has no units. For glass on glass 0 4. A car with mass 2000 kg drives with speed 100 km h on a wet road with friction coefficient 0 2. The friction coefficient between the object and the surface is 0 62.

For polished oiled metal surfaces less than 0 1. However it is possible to find tables in the literature for friction coefficients between various materials. The dynamic coefficient of friction are. The friction force can be calculated as.

Where μ s is the coefficient of static friction and μ k is the coefficient of kinetic friction. F f 0 62 100 lb 62 lb 1 lb 0 4536 kg. For example static friction can prevent an object from sliding down a sloped surface. The basic raw materials are coal iron ore limestone and various chemicals.

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. 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.

Example car braking friction force and required distance to stop.
