Computing coefficient of friction without experiment

AI Thread Summary
Calculating the coefficient of friction between two solid materials without experimental data is theoretically challenging due to the complex electromagnetic interactions at play. While some suggest using simulations or intermediary materials for comparison, the consensus is that friction cannot be accurately derived from first principles. Empirical methods remain necessary for practical analysis and theory development. The discussion highlights the limitations of current understanding and computational power in addressing this problem. Ultimately, the calculation of friction remains an unresolved challenge in materials science.

Is there theoretically any way to compute a coefficient of friction (solid on solid) without an experiment between the two materials? Say, some kind of simulation, or perhaps comparing both materials to an intermediary material?

If you can trust Wikipedia,

"... Friction is not itself a fundamental force but arises from fundamental electromagnetic forces between the charged particles constituting the two contacting surfaces. The complexity of these interactions makes the calculation of friction from first principles impossible and necessitates the use of empirical methods for analysis and the development of theory. ..."

Sounds like a challenge, can't be done! Start calculating, you know what the answer has to be.
 
I'm sure it CAN be done. We just don't understand enough about it and/or don't have powerful enough computers. Yet.
 
The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
