   •For example, to  transmit 10kw power 1200mm2 clutch plate contact area is required 

    as per the design calculations.

   •Instead of providing one big clutch plate of contact area1200mm2

   •six clutch plates each of 200mm2  will reduce the size of the clutch

   •Space limitation such as in two wheelers and racing cars
