The friction coefficient of marble on plastic and iron on plastic is not readily available in published literature and varies based on the type of plastic and the surface finishes of both materials. To determine these coefficients, one must conduct a simple experimental test by measuring the angle at which one material begins to slide over the other. The tangent of this angle provides the friction coefficient. This method is straightforward and effective for obtaining the necessary values.
