The moment M required to cause sliding of one plate against the other is given by:
FRICTION BETWEEN TWO MATING PLATES
Friction between circular surfaces under distributed normal pressure occurs in pivot bearings, cluctch plates and disc brakes. Shown below are two circular plates, which are brought together by the application of compressive force P.
The moment M required to cause sliding of one plate against the other is given by:
Application of Friction |
Thus,
Here, b is the total angle of wrap and should be expressed in radian. If the belt is wrapped around a drum n times, the angle would be |
