coefficient of friction

n. pl. coefficients of friction
The ratio of the force of friction between an object and a surface to the frictional force resisting the motion of the object.

coefficient of friction

n
(General Engineering) mechanical engineering the force required to move two sliding surfaces over each other, divided by the force holding them together. It is reduced once the motion has started
ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.coefficient of friction - the ratio of the weight of an object being moved along a surface and the force that maintains contact between the object and the surface
coefficient - a constant number that serves as a measure of some property or characteristic

An absorbent belted-article comprising an absorbent pad and a separate belt to which the absorbent pad is detachably attached and which is to be placed around the waist of a wearer to hold the absorbent pad when the belted-article is being worn, wherein the absorbent pad includes a chassis which comprises a liquid-permeable top sheet and a liquid-impermeable back sheet oriented away from the wearer and an absorbent core between the top sheet and the back sheet, and wherein the absorbent pad is detachably attached to the belt by an attaching arrangement, wherein the difference in kinetic coefficients of friction between the back sheet of the absorbent pad and an outwardly oriented surface of the belt is 0.
Some work has looked at friction at elevated temperatures but much of this has been associated with the polymer/mold interface and in particular its role in determining ejection forces in injection molding [14, 15], Although the majority of such work is for conventional metal molds, coefficients of friction between molded polymers and rapid tool materials (thermoset polymers) have been reported and shown to be highly material and temperature sensitive [16].
The solution space of torque profiles was determined for various rotation times and coefficients of friction between foot and floor.
