The magnitude of the limiting friction bears a constant ratio to the normal reaction between the two surfaces of contact and this ratio is called coefficient of friction. Coefficient of friction, µ = F/N Where F= Force of friction N= Normal reaction
At the contact surface, two reaction force of friction “F” and normal reaction “N” acts and combined graphically to get the reaction “R” which acts at angle “θ” called angle of friction. tan θ = F/N = µ
The angle between the resultant reaction and the normal reaction to the plane on which the motion of the body is impending. tan α = F/N = µ
The maximum inclination of the plane on which a body, free from external forces, can repose is called angle of repose. tan ø = F/N
The inverted cone with semi central angle “α” equal to limiting frictional angle “α”, is called cone of friction. Engineers often refer to either the coefficient of friction or the angle of friction. This section describes their relationship and goes on to explain the Cone of friction: Let R be the normal reaction at a point of contact O and F the ...
Hence, when limiting friction is offered the line of action of the resultant reaction should always lie on the surface of an inverted right circular cone whose semi-vertex is λ. This cone is called the cone of friction.

Sep 11, 2011 · This cone is called the cone of friction. If friction is not limiting, the angle made by the total action at O will be less than . Hence whether the friction be limiting or not, the direction of the total action at O must be inside or on the cone of friction.
