Friction Coefficient for Design Materials: PTFE, PP, PVDF, etc.

AI Thread Summary
Friction coefficients for materials like PTFE, PP, PVDF, PFA, and TEFLON are typically determined through experimental methods rather than theoretical calculations. While suppliers often provide limited data, resources like Wikipedia can offer a starting point for understanding friction coefficients. The distinction between static and kinetic friction is crucial when measuring these coefficients. Accurate values depend on the specific conditions of the materials in contact. Experimental testing remains the most reliable approach for obtaining friction coefficients in design applications.

Hallo, does anybody knows where to get friction coefficients for different materials used in design (PTFE; PP; PVDF; PFA; TEFLON; VESPEL) or how to calculate them? Suppliers do not give a lot of data,..is there a theory behind to estimate friction coefficient? thanks in advance!

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...
