I'm just curious...why are they called "shear" webs? I thought the main goal of the shear web was to restrict the opposing lateral movements of the top and bottom spars under stress to add stiffness to the wing, to resist the bending of the wing when subjected to positive or negative G's.
That's what I thought.
You're right. When airpressure tries to lift the wing, it is "Held down" in the center by the weight of the Fuse. If all you had were two spars (pivoted in the center of the Fuse) and you lifted them, they would "Shear" against each other.
