Wind Force and Swing on a Suspended Load
Velocity pressure, lateral wind force, and swing angle on a suspended load from the sail area, wind speed, and shape coefficient. The manufacturer's in-service wind limit governs.
Formula and source
q = 0.00256 x V^2 (ASCE velocity-pressure constant); wind_lb = q x sail_area x shape_coef; swing_deg = atan(wind_lb / load_weight) x 180 / pi.
ASCE 7 velocity-pressure constant (the same 0.00256 the wind-pressure tile uses) and OSHA 1926 Subpart CC by name; first-principles.
