Tricky to calculate wind loads for grills (there's a lot of interaction between the wires and it's very wind speed dependent).. most of the time you can just be conservative and assume it's a solid surface... 6 square feet for yours (if it's actually rectangular, not oval). > > >2.

Does anyone know under what conditions it is 200 Newtons so >I could calculate the area of it? 200N = 44lb Nothing on the wimo.de website talks about wind speeds...Perhaps there is a DIN standard? _______________________________________________ Sent via AMSAT-BB@amsat.org.
