possible variation in LCB position, a grid was adopted as shown by the dotted lines in 

 Figure 1.* 



For any one block coefficient and LCB position, a total of nine models was run in 



Lb 

 which the — and — ratios were varied. The pattern for a typical case (Cd = G.60) is

shown in Figure 2.
