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.

Dotmar epp pty ltd. The frictional force can be expressed as. References learn more about contacts. For rubber on tarmac close to 1 0.

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. At what ambient pressure. Friction coefficient table of solid lubricants metals plastics and anti friction materials. What kind of rubber.

Static friction is friction between two or more solid objects that are not moving relative to each other. Is this in atmosphere water vacuum some other environment. Static and kinetic coefficient of friction. What kind of plastic.

For glass on glass 0 4. The coefficient of static friction typically denoted as μ s is usually higher than the coefficient of kinetic friction. 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. Please use one of the following formats to cite this article in your essay paper or report.

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. Typical values for the coefficient of friction when sliding is occurring i e. The friction force is the force exerted by a surface when an object moves across it or makes an effort to move across it. Dry steel dry steel 0 70 0 57 0 80 greasy steel dry steel 0 23 0 16 0 90 greasy steel greasy steel 0 23 0 16 0 90 dry aluminiumdry steel 0 70 0 50 0 85 dry aluminiumgreasy steel 0 23 0 16.

For example static friction can prevent an object from sliding down a sloped surface. The coefficient of friction between two materials in relative sliding may depend on contact pressure surface roughness of the relative harder contact surface temperature sliding velocity and the type of lubricant whether the level of contamination. The dynamic coefficient of friction are. Stretched compressed in other words the question c.

F f μ n 1. For polished oiled metal surfaces less than 0 1. μ static μ s or kinetic μ k frictional coefficient. F f frictional force n lb.

Showing the concept of coefficient of friction. N normal force between the surfaces n lb there are at least two types of friction forces. The coefficient of friction is the ratio of a force to a force and hence has no units.
