Historical abstract

deutsch


Already the Egypts were occupied with the problem of friction. From historical traditions we know that they weted the sand on which they transported their stones. Today we know that this reduced the friction coefficient indeed.

The macroscopic friction laws, that we know, have been discovered during the last centuries by Leonardo da Vinci , Amontons, Euler and Coulomb.
