The Wood Handbook (FPL 1999) states that the wood-wood coefficient of friction
is dependent on moisture content (MC) and surface roughness.
If a claim of a slippery surface arises, determination of the coefficient of friction
through testing may help in the evaluation of the claim.
The second classification group, and by far the most popular is that group consisting of lubricants applied as a surface coating, and it is in this group that both the reduction in the coefficient of friction
, as well as the ability to control the level of lubricity, becomes possible.
5] as a function of lubrication's coefficient of friction
[mu] at the constant tool speed [v.
They differ from traditional lubricants primarily in the controlled coefficient of friction
that they provide on the railhead or top surface of the rail.
Typical test options include: tension; compression; load/displacement cycling; constant load displacement; texture profile analysis and coefficient of friction
They maintain greater tension for longer periods of time and have a high coefficient of friction
to minimize slippage.
A variety of materials and finishes are used to engineer the optimal coefficient of friction
, helping to achieve target end-use specifications.
The A2 brakes incorporate an improved piston design for longer service life at higher pressure, Heavy-duty graphitic friction material provides superior energy capability, high and stable coefficient of friction
and smooth engagement, the company said.
The Borden Graphics Group, Cincinnati, OH, has developed a custom-matched color line of skid-resistant aqueous flexographic inks designed to impart high coefficient of friction
properties to corrugated containers and trays.
In fact, the coefficient of friction
for the biggest rock was about 0.
The coefficient of friction
is, however, very poorly understood and very difficult to measure.
