## angle of friction

n
(General Physics) physics the angle of a plane to the horizontal when a body placed on the plane will just start to slide. The tangent of the angle of friction is the coefficient of static friction

where: Q = mg; P = mj; m is the mass of the particle; g is gravitational acceleration; j is inertial acceleration of the particle; F = fN, N is the normal reaction of the transporter surface; f = tan[phi] is the factor and tangent of the angle of friction between the particle and the transporter surface.
The flow properties of DDGS (including cohesion, effective angle of friction, internal angle of friction, yield locus, flow function, major consolidating stress, and unconfined yield strength) have been studied using the Jenike shear tester.
Ingold  reported that the maximum angle of friction decreases while the surcharge load increases from the pullout test result about full-scale reinforced earth retaining walls and also reported that the vertical stress with angles of low friction at an interface between earth and geosynthetics is greater than the coefficient of earth friction.
where [[phi].sub.b] is the angle of friction between the joint surfaces shifting across one another, i is the asperity angle (see Figure 1) - deflection of friction surface forced by the displacement, resulting from the uneven surface, [[phi].sub.r] is the residual angle of friction of joint surfaces moving across one another in a slip, while c is the cohesion at joint contact point.
* The heat has direct correlation with modification of kaolinte angle of friction
