Rubber Plastic Coefficient Of Friction

Static friction results from the normal force of two objects in contact acting opposite the intended motion of one surface against the other.

Rubber plastic coefficient of friction.

μ static μ s or kinetic μ k frictional coefficient. F f frictional force n lb. Plastic co efficient of friction co efficient of friction of engineering thermoplastics. References learn more about contacts.

The coefficient of static friction typically denoted as μ s is usually higher than the coefficient of kinetic friction. 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. Typical values for the coefficient of friction when sliding is occurring i e.

Friction coefficient table for various material pairs in atmosphere and vacuum see the definition of friction coefficient is shown below the data was collected from various sources 1 2 3. The friction force is the force exerted by a surface when an object moves across it or makes an effort to move across it.

N normal force between the surfaces n lb there are at least two types of friction forces. Is this in atmosphere water vacuum some other environment. For polished oiled metal surfaces less than 0 1.
