Rubber Coefficient Of Friction Table

N normal force between the surfaces n lb there are at least two types of friction forces.

Rubber coefficient of friction table.

The coefficient of static friction typically denoted as μ s is usually higher than the coefficient of kinetic friction. Static friction is friction between two or more solid objects that are not moving relative to each other. Coefficient of friction dry lubricated test method static sliding static sliding note. The table of values.

μ static μ s or kinetic μ k frictional coefficient. The value of μ s is generally higher than the value of μ k for a given combination of materials. The only way to determine the accurate coefficient of friction between two materials is to conduct experiments. The coefficient depends on temperature and other things.

F f μ n 1. 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. References learn more about contacts. The frictional force can be expressed as.

F f frictional force n lb. For example static friction can prevent an object from sliding down a sloped surface. Dry steel dry steel 0 70 0 57 0 80 greasy steel dry steel 0 23 0 16 0 90. Material contact properties table the table below shows material types and their commonly used values for the dynamic coefficient of friction and restitution.

However it is possible to find tables in the literature for friction coefficients between various materials. Static and kinetic coefficient of friction. 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. Showing the concept of coefficient of friction.

Static sliding static sliding. F r rolling resistance or rolling friction n lb f c rolling resistance coefficient dimensionless coefficient of rolling friction crf w m a g normal force or weight of the body n lb f m mass of body kg lb a g acceleration of gravity 9 81 m s 2 32 174 ft s 2 the rolling resistance can alternatively be expressed as. Rubber doesn t have a single constant coefficient of friction. Material 1 material 2 coefficient of friction.

The sliding lubricated values must be used with extreme care. Where μ s is the coefficient of static friction and μ k is the coefficient of kinetic friction. Friction coefficient table of solid lubricants metals plastics and anti friction materials. The friction force is the force exerted by a surface when an object moves across it or makes an effort to move across it.
