The angle between the resultant reaction and normal to the plane on which the motion of body is impending is known as-
Angle of limiting friction
However, when motion is impending, the friction force is at its limiting value, making "angle of limiting friction" the most accurate and specific term for the angle at the point of impending motion. While "angle of friction" is sometimes used loosely for the angle at any point, "angle of limiting friction" specifically refers to the maximum possible angle between the resultant reaction and the normal reaction.
