Does lubrication increase friction?
lubrication decreases friction unless you're lubricating with sandpaper.
How do you calculate the coefficient of friction?
It's hard to guess that in advance, though as a general rule you can guess that smooth surfaces have a lower coefficient of friction than rough surfaces, and lubrication usually reduces the friction. However, to get more precise information, this has to be measured. Of course, you can first search the Internet - somebody may already have measured it.
What is the coefficient of friction for marble?
The coefficient of friction is not defined for a single substance, but for two substances that have contact with each other - for example, marble with marble, marble with wood, etc.; it may also vary a lot depending on lubrication. That is, on a wet wet marble floor you'll slip easier - there is less friction - than on a dry one.
What is physical difference between surfaces with high and low coefficients of friction?
A high coefficient of friction may be caused by a rough surface. It may also be the result of surfaces sticking together, as in the case of rubber which tends to stick to certain surfaces, at least when it is dry. Lubrication - such as a thin layer of oil - tends to reduce the coefficient of friction.
Why is friction lubricating?
Friction is not lubricating. Lubrication diminishes friction.
Is the coefficient of friction up to 13 unit?
No. Coefficient of friction is not measured in units.
What factors determine the coefficient of friction?
quality of the Surface is affected to the Coefficient of friction
What are the two factors that affect the friction force between two surfaces?
The strength of the force of friction depends on the types of surfaces involved and on how hard the surfaces push together.
Is coefficient of friction or coefficient of limiting friction are same?
Limiting friction is just the maximum static friction force (if you go over that point static friction becomes kinetic friction).Let f = frictional force,c = coefficient of frictionN = Normal forcefmax = cN = limiting frictionAlthough the term coefficient of limiting friction is not really used, I'd assume it would just be "c" (it's a coefficient after all). So they would be the same.If you meant is coefficient of friction the same as limiting friction, than the answer is no. Coefficient of friction is just the "c" in the equation. Limiting friction however is the product of the coefficient and the normal force.
What decreses friction?
Lubrication.
What is the coefficient of friction of linoleum rubber?
You need two different materials to determine the coefficient of friction. Without another material you cannot know what the coefficient of friction is.
What are the units that friction is measured in?
The coefficient of friction is dimensionless; it has no units.
