SUMMARY

The highest coefficient of kinetic friction among the materials discussed is rubber on polyethylene, as confirmed by user consensus. The coefficient of friction serves as a theoretical model, with actual friction forces often differing from calculated values. The discussion emphasizes the importance of understanding real-world applications versus theoretical models in engineering contexts. For further reference, users can consult the friction coefficients table provided by the Engineers Handbook.

PREREQUISITES
  • Understanding of kinetic friction and its applications in engineering
  • Familiarity with material properties, specifically polyethylene and rubber
  • Basic knowledge of friction coefficient calculations
  • Access to friction coefficient tables for reference
NEXT STEPS
  • Research the properties of polyethylene and rubber to understand their frictional characteristics
  • Study the concept of adhesion and its impact on friction coefficients
  • Learn about experimental methods for measuring friction in various material combinations
  • Explore advanced friction models beyond the basic coefficient of friction
USEFUL FOR

Engineers, material scientists, and students studying tribology or material mechanics will benefit from this discussion, particularly those interested in the practical applications of friction in engineering design.

What has the highest coefficient of kinetic friction, steel on polyethylene, rubber on polyethylene, or polyethylene on polyethylene?

That would be infinity ... ie. complete classical adhesion.
The "coefficiant of friction" is just a model.

Commonly known as the ' coefficient of fiction ' in engineering .

Actual friction forces as measured for real sliding surfaces are often far different from calculated values .
