Ron, Thanks so much for your comments, > The center of load support of the rib is what you should be talking about, > and it can be moved to where you want it by asymmetric feathering, and > tapering. ****In regard to the half meter rib: Given a radius of 12 meters and chord of .47 meter the calculator predicts 2.1mm of crown or segment height. If the center of load support (high point and thickest part) is asymmetricly shifted off center of the chord, the calc cannot be accurate and their will always be less crown than desired? Still a bit confused. Gene
