Table of static and dynamic friction coeffcient and friction equations given in imperial and SI metric units.
The coefficient of friction is often denoted by the Greek letter, {eq}\mu {/eq}. As a coefficient it is a pure number that has no units of measurement. It is the ratio of how much force is needed to side the two surfaces over each other and the amount of force that holds them ...
In subject area: Computer Science A friction coefficient refers to the value that quantifies the level of friction between two surfaces in different environmental conditions. It is determined by comparing the variations of the coefficient measured during tests conducted at different temperatures and envi...
