V = Wind Speed
SQRT = Square Root
W = Trailer Weight
B = Trailer Width (Tire Center to Center), FT
L = Trailer Length, FT
H = Trailer Height (From Ground), FT
H2 = Tire Height, FT
For what it's worth, the formula gives an answer of about 63 (mph?) for my Scamp
13 (W=1600, B=5.5, L=13, H=7.25, H2=2
). Gusts, and even sustained winds, of that magnitude are common in parts of northern Arizona (and the California desert). I wonder if the formula takes into account the use of stabilizers. I also wonder how differing trailer profiles affect the dynamics.
