WebDec 28, 2024 · Sliding friction, more commonly referred to as kinetic friction, is a force that opposes the sliding motion of two surfaces moving past each other. In contrast, static … Webeffective, allows increasing the durability of the working bodies. The coefficient of soil friction depends on many factors, the main of which are mechanical composition and humidity. Changing the ratio of solid, liquid and gaseous phases in the soil leads to a change in the forces acting in the system “soil tillage tool - soil”.
