This board can withstand 10 ms (36 Kmh, 22.5 mph) winds head-on without yielding, recommended range 0-30 Kmh or 0-19 mph (theoretically*). br br This board was designed using SolidWorks, CFD results were obtained by passing dry air at STP and 50 humidity, over the board at 10 ms head-on using SolidWorks Flow Simulation Premium. Then it's physical effects on the board were calculated using FEA in SolidWorks Simulation Premium. br br This shows potential power of SolidWorks, CAD + CFD + FEA all in one, paperless projects.
