Question
A dimensionless quantity named after this force can be calculated using the Haaland equation or the Darcy-Weisbach equation. A quantity named after this force is plotted against the Hersey number on a Stribeck curve. This non-electrostatic force is independent of velocity by Coulomb’s law, and is independent of apparent surface area by the second of Amontons’ laws. Electricity is produced by this force in the triboelectric effect. The static form of this force equals the normal force times its namesake coefficient, denoted mu (“moo”). Lubricants reduce the effect of this force. For 10 points, name this force that resists objects sliding past each other. ■END■
ANSWER: friction [accept Darcy-Weisbach friction factor; accept coefficient of friction; accept static friction; accept dry friction]
