The ratio between the force necessary to move one surface horizontally over another and the pressure between the two surfaces.
Example sentencesExamples
- Such mills have large diameter rolls with surfaces that are roughened or ragged to increase the coefficient of friction.
- Nylon gears and other moving parts have low coefficients of friction and excellent wear-resistance and impact and tensile strengths.
- It appears that this more subtle effect accounts for the low coefficient of friction of icy surfaces.
- The coefficient of friction and other aerodynamic aspects in aircraft are more important than simply miles per gallon.
- In fact, the thickness of the oil determines its coefficient of friction and defines four distinct regions of lubrication.
