YES! I knew this concept existed but did not know its name. Bowden and Tabor (1950). Asperities. Never heard of it. That’s the parts that stick out when two surfaces come together in friction. It’s called the “Adhesion Theory of Friction” and it is the modern understanding of friction.
The “stick and slip” phenomenon. I knew it was a thing but did not know what the parts were called or the name of it.
