Angle of friction:

 

1603_Angle of friction.png

It can be defined as the angle made by resultant of normal reaction (R) and limiting force of friction (F) with normal reaction (R).

Let, S = Resultant of normal reaction (R) and limiting force of friction (F)

= Angle between S and R

tan =  F/R = µ

Note: The force of friction (F) is equal to µR
