Lug Geometry Ratios

The lug geometry ratios are non-dimensional ratios used for obtaining constants and efficiency factors in the determination of lug allowables. Please read AFFDL-TR-69-42, Chapt. 9, for expanded explanation. These values generally represent an axis on a efficiency factor graph. These values will always be calculated automatically based on values entered elsewhere in the program.
