Coefficient of friction of road and tire?
Coefficient of friction on raod and a tire varies depending on the condition of the road and tyre Wet Road: 0.4 Dry Road: 0.7 This is the average coeffecient for these conditions again it can vary
Why is braking less effective on a wet road than on a dry road?
Two reasons. The wet road has a lower coefficient of friction that the dry one. It is more slippery. The same goes for the brakes. If they are wet, they will be less effective because of the same reason. A higher amount of friction wastes more energy, in this case momentum, causing a loss of speed. http://en.wikipedia.org/wiki/Friction
Which has less friction a dry road or wet road?
a wet road also see hydroplaning
Why do Icy roads have less friction then dry roads?
Because ice is slippery. when pressure is applied to ice it melts so essentially the coefficient of friction is that of water.
The coefficient of static friction between the tires of a car a dry road is 62 the mass of the car is 1500 kg what maximum force is obtainable?
Frictional force, F = coefficient of friction, u x normal reaction, R Maximum normal reaction = Weight => Maximum frictional force = 62 x 9.8 x 1500 = 911400 N

An example of two surfaces that have a low coefficient of friction?
human joints are an excellent example. they have a static friction coefficient of .01 μs and a kinectic friction coefficient of .003 μkanother good example would be waxed wood on dry snow (as in a snowboard on a ski slope) this has a static friction coefficient of .04 μsHope this helped!
Which has less friction a dry road or a wet road?
A wet road has less friction since the water acts as a lubricant.
Which has less friction a dry road or wet road?

Why do cars skid more easily on rainy days?
The coefficient of friction between a tire and a wet road is LOWER than the coefficient of friction between a tire and a dry road. It should also be noted that during a dry period, roads are covered by a thin film of dust as well as oil that has leaked from vehicles. At first the rain mixes with these and creates a very slick surface, even further reducing the coefficient of friction. After the rain has washed away some of the dust and oil the roads are slightly less slippery, but still much more so than on a dry road. Note too that standing water can cause a tire to "Hydroplane" at high speed, with "high speed" being a variable that depends on the condition of your tires and the amount of standing water. Hydroplaning is a condition in which the tire is literally lifted off the surface of the road and rides entirely on a film of water.
What two surfaces have the highest coefficient in friction?
wood on dry concrete .......apex cant help you with nothing

What is a low mu surface?
This is a low coefficient of friction like driving on ice with a car versus driving on dry asphalt.
Why do you think the coefficient of friction varies so much for dry wood on dry wood?
Different types of wood have different coefficients of friction. As dense, hard, wood will tend to be smoother than a porous, soft, wood.
Why the coefficient of friction cannot be zero?
The coefficient of friction is an empirical measurement and has to be measured experimentally, and cannot be found through calculations. Rougher surfaces tend to have higher effective values. Most dry materials in combination have friction coefficient values between 0.3 and 0.6. Values outside this range are rarer, but Teflon, for example, can have a coefficient as low as 0.04. Therefore, a value of zero would mean no friction at all, an ELUSIVE property even magnetic levitation vehicles have drag.
