Internal Friction

internal friction [in′tərn·əl ′frik·shən]

(fluid mechanics)

viscosity

(mechanics)

Conversion of mechanical strain energy to heat within a material subjected to fluctuating stress.

In a powder, the friction that is developed by the particles sliding over each other; it is greater than the friction of the mass of solid that comprises the individual particles.

Friction, Internal

a group of various processes within solids, and in liquids and gases, that lead to the irreversible dissipation of mechanical energy during deformation through the transformation of mechanical energy into heat. (SeeINTERNAL FRICTIONIN SOLIDS; regarding internal friction in liquids and gases, seeVISCOSITY.)

New Italian stalion by Gulf Weekly This, along with technology like low rolling resistance tyres that are 28% more fuel efficient, a revised final gear ratio and low viscosity engine oil reducing internal friction, gives the Colt 56mpg.
