Eames' method was selected for these computations as 

 an expediency ;, since solutions for the cable equations 

 based on Whicker 'a loading functions were not readily avail- 

 able. It is believed J however, that the differences in 

 catenary estimates made by the two methods is small in the 

 present case. This may be shown by considering the differ- 

 ences in the loading functions basic to the two assumptions. 



First, for large values of the ratio of the weight 

 per unit length of cable to the resistance per unit length, 

 i.e., for low towing speeds, the ratio of the functions 

 approaches unity. Second, for large values of the cable 

 angle, the ratio of the functions approaches unity. Third,, 

 for the initial cable angle pertaining to the present case, 

 ^> = 81® , the radius of curvature of the cable in the neigh- 

 borhood of the depressor is found to be 1,675 feet on the 

 basis of Eames' assumptions, and 1,680 feet on the basis 

 of Whicker 's assumptions, i.e., they may be considered 

 equal.
