What's the Coefficient of Static Friction for Metal on Metal, and for Leather on Metal??I also need sources for the values.
well, steel is a type of metal. It's sort of like asking the difference between a bug and an ant, an ant is a bug, but not every bug is an ant. Likewise, steel is metal, but not all metal is steel. Gold is metal, Silver is metal, Iron is metal, Steel is metal.
