5. According to the table, Approximate Coefficients of Friction, which surface would offer the greatest traction for a rubber tire?
(1) dry concrete
(2) wet concrete
(3) dry asphalt
(4) wet asphalt

The dry concrete will offer the greatest traction for the rubber tire.

The friction between the rubber tire and the surface is calculated as follows;

[tex]F_f = \mu_k N[/tex]

where;

  • N is the normal reaction due to weight of the rubber tire
  • [tex]\mu_k[/tex] is the coefficient of kinetic friction

The coefficient of friction of the given different surfaces are listed below;

  1. Dry concrete = 0.68
  2. Wet concrete = 0.58
  3. Dry asphalt = 0.67
  4. Wet asphalt = 0.53

Thus, from the values of the coefficient of kinetic friction between the road and the surface, the dry concrete will offer the greatest traction for the rubber tire.

Dry asphalt surface offer the greatest friction for a rubber tire as compare to other surfaces.

Dry asphalt is considered a surface that offer the greatest friction for a rubber tire because it has a rough surface which provides more friction to the tire. Asphalt is a mixture of aggregates, binder and filler that is used for constructing and maintaining roads, railway tracks, airport runways etc.

Aggregates used for asphalt mixtures could be crushed rock, sand, gravel. Wet asphalt are slippery due to the presence of water on the surface of asphalt as compared to dry asphalt so we can conclude that dry asphalt surface offer the greatest friction for a rubber tire as compare to other surfaces.
