Question:-
In a plate clutch axial force is 4kN. The inside radius of contact is 50mm and the outside radius is 100mm. for uniform pressure the mean radius of friction surface will be:
Option (A)
78mm
Option (B)
60mm
Option(C)
75mm
Option(D)
80mm
Correct Option:
(A)
Question Solution:
rm = (2/3)[(r30) / (r20)] = (2/3)[(1003-503) / (1002 - 502)] = 77.77
