We must now consider the question of how to express F 
and G. Actually, there is presently a great need for experi- 
mental data on the values of these loading functions for 
faired shapes at angles to the stream. As a result, there 
is still considerable disagreement as to the functional 
relationship between F and G and the stream angle, 9. Eames, 
in Reference 2, adopted a simplified approach to the problem 
and made the following assumption: 
Be si 22 
ae (22) 
S = cos 9 (23) 
R : 
This results from the assumption that the drag, R, is 
always parallel to the stream which would appear reasonabie 
if the total drag were due only to shear forces on the surface. 
This would not be the case unless the faired cable approached 
a flat plate of vanishingly small thickness. Eames contends, 
however, that for reasonably high chord-to-thickness ratios, 
this is a good approximation and the resulting Simplification 
of the equations for the cable configuration justifies its 
use. Whicker, in Reference 3, attempts to reconcile data on 
faired struts and arrives at the following expressions which
