Coefficient Of Friction Equation And Table Chart

Static friction is friction between two or more solid objects that are not moving relative to each other. For example, static friction can prevent an object from sliding down a sloped surface. The coefficient of static friction, typically denoted as s, is usually higher than the coefficient of kinetic friction.

Internal Friction Angle

Mar 04, 2005 A simple internal friction angle is the observed angle of repose of the stockpile. Usually, with bigger rock pieces this angle is in the rangle of 35-45 degrees, depending on how the pile is formed. This is not a friction angle. It is the dilation angle of particles moving on its surface rilling over one another.
