Question

A multiple disk friction clutch has three driver disks and two driven disks. If the number of driven disks are increased to three and number of disk on driver remains same then the torque transmission capacity would increase by

• A. 33%
• B. 20%
• C. 25 %
• D. None of these

Answer 1

The correct option is C 25 %

For 3 driver and 2 driven disks we will have (3 + 2 - 1) = 4 contact surfaces.


For 3 driver and 3 driven disks we will have ( 3 + 3 - 1) = 5 contact surfaces.


So, torque transmission capacity would increase by $\frac{5-4}{4}\times 100=25$%
