drag of the cable per unit length when the cable is normal 
to the stream. The drag is given by: 
R= cy & av? (1) 
where: 
cp is an empirical drag coefficient, 
p is the mass density of the fluid, 
qd is the diameter of the cable, and 
V is the stream velocity. 
To reduce the problem to a case of practical interest 
several assumptions will be made. These and assumptions 
already made are listed as follows: 
les The cable is assumed to be completely flexible 
and thus cannot sustain a bending moment. 
as The cable is assumed to lie in a vertical plane 
parallel to the direction of motion. 
3. It will be assumed that the cable to be used is 
American Steel and Wire Type H. This cable is of 
the double-armor type which is available in various 
diameters with a variety of electrical cores.
