Hi Guys,
How does someone go about designing the shape and depth of a rib for a wing?
I know that the percentage of arc camber is the percentage of a wing chord. I also read a while back that a builder draws a circle of "X" number of inches in diameter, then takes a section of the circumference as long as the chord, but then, depending on the diameter of the circle you could theoretically end up with a semi-circle for a wing rib (that ain't gonna work). I look at the rib outline in Williams' book on page 43, for EZB1, then I look at the rib profile on page 90 for the pennyplane and there's a definate difference in shape and not just the arc.
So where might I find this information in language that I can understand? For instance, lets say that I'm going to be flying in a place with a lower cieling than where I usually fly and I want to build a wing that will accomidate the lower cieling.
I hope I'm not opening a can of worms here but, I sure would like to know a bit more about this aspect of design.

Thanks in advance,

Ren
