Thank you all for the information. I knew I could find good"stuff" out
there.
The wind generator (not an antenna) I was planning has limited
information available as to loads. ie. No Flat Plate or FPE numbers.
The only statement is that the tower must take a 200 pound lateral
thrust and not deflect more than six inches with winds of 200 mph. The
Trylon T-200 tower specs. for my maximum wind speed area (from the
chart at their web site),
shows that the T-200 will take a 42 pound lateral thrust at winds of 85
mph.
If 120 mph winds cause the wind generator to exert 200 pounds of
lateral thrust, what speed of the wind will yield the 42 pound maximum
lateral thrust that the tower will hold? Please show your work.
