Which material combination has the highest coefficient of kinetic friction?

AI Thread Summary
The discussion centers on identifying which material combination has the highest coefficient of kinetic friction among steel on polyethylene, rubber on polyethylene, and polyethylene on polyethylene. It suggests that rubber on polyethylene likely has the highest coefficient, although this is not definitive. The conversation highlights that the coefficient of friction is a theoretical model and actual friction forces can vary significantly from calculated values. The term "coefficient of fiction" is noted as a common misnomer in engineering contexts. Overall, the topic emphasizes the complexities of friction measurements in practical applications.

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 .
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
