- Folks, Just talking with a friend about a 'wind problem' is there a nice formula that will give a reasonable estimate of the likely wind survivability based on: a mass A of surface area B suspended C

- Depends on what you call "reasonable" You can estimate it by taking Wind drag = rho*Cd*Area*Vwind^2, where rho is density of air and Cd is the drag coefficient of your thing A cylinder (e.g. a pipe)

- Jim, Thanks, nice and simple eh? :-) Reasonable = +/- 20% then a tad (metric or imperial tad, not important) Of course the answers now breed more questions. JUsta check list to see if I'm doing this

- Use 1 for a "flat plate" (cross section perpendicular to wind) m/sec if you want to keep units consistent. Newtons Force times distance - Newton Meters Need to scrounge up the equation for bending of
