Paper Friction Problems (Troubleshooting Guide)

Two more useful definitions are static friction and dynamic friction. The static frictional coefficient is the ratio of tangential to perpendicular force at the point where motion (slippage) is initiated. The dynamic coefficient is the same ratio at a defined rate of sliding, and usually the average value is reported.

Mill (grinding) - Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting.
