Maybe this is better, convert wing loading \dfrac{kg}{m^2} to pressure P=\dfrac{g\cdot kg}{m^2} , and then put that into the cylinder stress formula. Or not, I don’t know.
The idea is that this is an alternative to Beams - Fixed at One End and Supported at the Other - Continuous and Point Loads and bending loads for soft skin kites so that you may bound your scaling factor estimations. Also it could be useful if you are trying to design a soft skin kite.
If you take a wing loading of 50 \dfrac{kg}{m^2} , the maximum of a ship kite, page 9: Deformation and Aerodynamic Performance of a Ram-Air Wing, and some other arbitrary values, you get: \dfrac{50\cdot9.8\cdot1}{2\cdot0.001}=245kN . You could use more accurate numbers to get more accurate results.
I don’t know if this equation is accurate, but I do think all variables are relevant.
