Hi,I have seen a number of ultralights with wings whose ribs don't have webs e.g this Affordaplane:
I once learnt that the webs in wing ribs help to transfer shear forces as well as wing loads on the wing skin to the spars,so my question is how will these "shear forces" be transfered from the skin to the spar when the webs are absent.
Ps:1.wing ribs with webs⬇
