y' Normalized space coordinate (= 1 - x'). 



y' Value (s) of y' at which the amplitude of the dynamic stress in the 



cable for sinusoidal variation with time becomes maximum. 



a Drag coefficient. 



Etimensionless drag coefficient for the array, equal to the ratio of 



the drag to the inertial force.

H Parameter equal to the ratio of the total mass of the cable to the 

 dynamic mass of the array. 



V Kinematic viscosity, 

 p Density of water. 



p Density of cable. 



Tensile stress in cable due to static loading.
