This is the cause of all the friction between the ladies and the gentlemen.
Results shows that changes in lattice orientation and surface decoration cause variation of the friction coefficient by 5 orders of magnitude, from 0.06 to 42 × 10−3, as a result of changes in the collision angle between atoms at the interface.
The instantaneous drop of the relative velocity caused instantaneous change of the friction forces.
Crankshaft mechanism in internal combustion engine causes nearly half of the friction loss originating in piston-ring-cylinder contacts.
The nitrogen also reduces the root mean square surface roughness from 1.27 to 0.46 nm, and causes a reduction of the friction due to an increase in the sp2-graphitelike carbon phase, with the lowest friction coefficient of 0.18 for the NbC1.99 N0.69 film.
But it's been endemic for years in the entertainment industry, and is the cause of continuing friction between truckers and trucking companies at the ports of Los Angeles and Long Beach.
Just who exactly has the power to address the concerns with the power generators is the cause of much friction.
Acadia's border was not formally demarcated by the Treaty of Utrecht, which became a cause of ongoing friction between the British and French, especially on the Isthmus of Chignecto, which both sides eventually fortified.
The nearby Sikalima stream is another cause of friction between the Chinese-run mine and the cattle-herding community in the area, who rely on it as a source of drinking water.
