Rubber Plastic Coefficient Of Friction

Is the rubber subject to other forces.

Rubber plastic coefficient of friction.

The frictional force can be expressed as. Is this in atmosphere water vacuum some other environment. Stretched compressed in other words the question c. F f μ n 1.

For example static friction can prevent an object from sliding down a sloped surface. 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 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. Static friction is friction between two or more solid objects that are not moving relative to each other.

The coefficient of static friction typically denoted as μ s is usually higher than the coefficient of kinetic friction. μ static μ s or kinetic μ k frictional coefficient. What kind of plastic. 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.

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.

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