That is really wierd. Can T-bolts do it to? I'm guessing it probably has something to do with the fiberglass too, being that fiberglass is lightweight.
It would make sense to do so. Wind pressure in pounds per square foot varies as the square of the speed. Wind load can be huge. (It's the largest load on tall buildings, for example, not weight).LtKernelPanic wrote:I wonder if some sirens don't have a mechanism that once so much force is applied they begin to rotate to protect them from damage. I noticed one day a couple weeks ago on my way to work the Whelen that I go by was pointing one way but on the way home it was another. The weather was hot and sunny, no storms but windy as hell. There weren't any warnings and it wasn't the monthly test day either.
