Limiting Angle of Friction in Friction Devices Formulas

The Limiting Angle of Friction is defined as the angle which the resultant reaction (R) makes with the normal reaction (RN). And is denoted by Φ. Limiting Angle of Friction is usually measured using the Degree for Angle. Note that the value of Limiting Angle of Friction is always positive. Typically, the value of Limiting Angle of Friction is smaller than 90.
