It is fifty-five minutes past ten; we have been gone about eight minutes; and if our initiatory speed has not been checked by the friction, six seconds would be enough for us to pass through the forty miles of atmosphere which surrounds the globe.
Hundreds of meteorites, ignited by the friction of the atmosphere, irradiated the shadow of the luminous train, and lined the cloudy parts of the disc with their fire.
The plateaus of powder, trapped in the contact along cutting fibers by the friction
, accumulated and compacted to form patches.
The most common positive effect in the boundary friction
between surfaces with a partially regular microrelief can be explained in relation to the lubrication conditions improved by increasing oil absorption (Schneider 1982, 1998, 2001).
Policy responses that fail to take into account how quickly technologies and the innovations they enable are evolving can cause more, rather than less, friction
8220;We're very excited to have fresh talent as a part of the GMP Friction
Products team this summer,” said Jerry Lynch, COO and President of GMP Friction
of the pad against the disk is however responsible for the majority of stopping power .
The average car clocks up about 13,000 km per year, and in the meantime burns 340 litres of fuel just to overcome friction
, costing the driver EUR 510 per year.
The method of tying orthodontic wires to the brackets also influences the amount of friction
The ultra-smooth finish minimizes friction
drag between the hull and the water, improving fuel efficiency by 3-5% compared to an identical vessel with a conventional hull coating.
In 2008, a literature review and analysis of rubber friction
research produced evidence for existence of this microhysteretic force.
Key words: Degradation, Lubricant, Friction
In addition emphasis is being placed on reducing energy while vehicle is driving, and there is a demand to further reduction for rotational friction
in order to get better efficiency for fuel and electric consumption even for hub bearings that support axle.
The additional problems of friction
brake noise and judder aren't mentioned even though they cause noise pollution and huge expense to vehicle manufacturers if post-sale rectification is required.
The coulomb friction
model is used in  for rotational system of clutch.
