The following is not a law of static friction:

The force of friction depends upon the roughness of the surface

The force of friction always acts in a direction opposite to that in which the body tends to move

The magnitude of the limiting friction bears a constant ratio to the normal reaction between two surfaces

The force of friction is dependent upon the area of contact

Lami's theorem states that

Three coplanar forces acting at a point will be in equilibrium, if each force is proportional to the sine of the angle between the other two

If three forces acting on a point can be represented in magnitude and direction by the sides of a triangle, the point will be in the state of equilibrium

Three coplanar forces acting at a point will be in equilibrium if each force is inversely proportional to the sine of the angle between the other two

Three forces acting at a point are always in equilibrium
