6	Purpose:
7	This spreadsheet calculates the equivalent number of bolts to be removed from the gross area of a member under tensile loading.
8
9	Variables:
10	nb = The number of bolts along the failure path.
11	s = Longitudinal center-to-center spacing (pitch)
12	g = Transverse center-to-center spacing (gage)
13	Zigzag Count = The number of bolt staggerings with the same configuration.
14	dh = Bolt hole diameter (Typically bolt diameter + 1/16")
15	Critical Spacing = The spacing beyond which a staggered failure path does not control for the given gage.
16	ns = The equivalent bolt holes corresponding to the spacing.									Ceiling
17	ne = The effective equivalent number of bolt holes.									1.00E-07
