What is the average coefficient of friction for a dry road?

The average coefficient of friction for a dry road is typically around 0.7-0.8. This means that the frictional force between tires and the road surface is 70-80% of the normal force pressing the tires onto the road.


Why does a wet road appears blacker to a driver than a dry road does considering that a dry road is more of a diffuse reflector than a wet road?

The water is shiny, your head lights reflect as if it were a mirror so absence of light is black. Day time has the same answer with the exception that driving into the sun is like driving into a laser beam.


Which has less friction a dry road or wet road?

A dry road typically has less friction than a wet road. Water on the road surface can reduce tire grip, leading to an increase in friction and longer stopping distances. The lower friction on wet roads can increase the risk of skidding and losing control of the vehicle.


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 does oil on the road make rainbows in a rain puddle?

Oil on the road creates rainbow patterns in rain puddles because of thin film interference. When light hits the oil slick, it reflects off both the top of the oil and the road's surface. The varying thickness of the oil causes interference, resulting in the colorful patterns seen in the puddle.

Why roads dry quickly after rain?

The water remains of the surface of the road and thus is able to evaporate quickly when the rain stops and the sun comes out.


Why wet roads dry quickly after rains?

The water remains of the surface of the road and thus is able to evaporate quickly when the rain stops and the sun comes out.


When it rain shower the road surface is likely to be most slippery?

first 30 minutes after the rain


What is the curved surface of a roman road designed to do?

The curvature made the rain drain to the sides of the road.


When the road is wet it takes times longer to stop?

Yes. There is less frictional force between the car tyres and a wet road surface than with a dry road surface.


Why is the road is most slippery when it begins to rain?

As rain falls, the water mixes with oil found on the road's surface, making the pavement slippery.that we use the alakalis to the litmus paper


What is rain?

Rain is a type of precipitation, a product of the condensation of atmospheric water vapour that is deposited on the earth's surface. It forms when separate drops of water fall to the Earth's surface from clouds. Not all rain reaches the surface; some evaporates while falling through dry air. When none of it reaches the ground, it is called virga, a phenomenon often seen in hot, dry desert regions.


Why do drag racing tires have no tread - isn't tread supposed to increase traction?

In ideal conditions, dry weather, great road surface etc. slick tyres offer more rubber to the road therefore greater traction. Normal road tyres are a compromise, on any one trip your car may have to cope with sunshine, rain, sleet, snow, bad road surface, smooth surface, mud, and gravel. Manufacturers have to make a tyre that can cope with that. The result is the tyre on your car.


When During a rain shower the road surface is likely to be most slippery?

In the 30 minutes after the shower begins

The road is most slippery A. after a long rain. B. when it is new. C. during the first half hour of the rain.?

The road is most slippery during the first half hour of the rain (C) because the rain mixes with the oil and dirt on the road, making it more hazardous for driving. After a long rain (A), the water washes away some of the oil and dirt, reducing the slipperiness of the road. A new road (B) typically has better traction due to the roughness of the surface.


Many roads are most slippery when it first starts to rain or snow because?

Accumulated oil residue from the traffic flow during dry weather becomes wet and moves to the surface of the travelled lanes because oil is lighter than water. This makes the road surface extermely slippery.
