μ static μ s or kinetic μ k frictional coefficient.
Static friction is friction between two or more solid objects that are not moving relative to each other.
The maximum force of static friction can be calculated by multiplying the normal force by the coefficient of friction specific to the pair of materials in contact.
In the present work friction and sliding wear behaviors of indigenously developed ethylene propylene diene monomer rubber epdm of different hardness have been studied against steel counterpart in dry condition.
Further aim of this work was to investigate on how the friction and wear properties of the epdm rubbers depend on the configuration of the testing rigs.
The coefficient of static friction typically denoted as μ s is usually higher than the coefficient of kinetic friction.

Fric tion force normal load and coefficient of friction cof were determined.
The rubber stocks were prepared in a laboratory internal mixer and the curatives were introduced on a laboratory open mill.
N normal force between the surfaces n lb there are at least two types of friction forces.
The results of the tests and the simulations were compared with each other and discussed.
The coefficient of frictions cof and specific wear rates of the epdms were determined.
The friction values used in the material interaction table are generalized values based on the following references.
The friction coefficient cof of the epdm seal and plate was not experimentally measured and is therefore unknown in this study.
A similar tendency was found for the cof in rop tests.
It was found that with increasing cb content the specific wear rate was reduced.
Both cof and wear rates of the epdm mixes strongly depended on the test configurations.

The friction force is the force exerted by a surface when an object moves across it or makes an effort to move across it.
The resistance to polar substances and steam are also good.
Studies in the literature suggest that the cof between a dry epdm.
