Hello All,
please forgive me if this is the wrong place to ask for the following
information:

Assuming an antenna A of windrelevant cross-section Ca, on a
telescoping mast of height Hm (maybe with windrelevant cross-section
Cm), subjected to wind of velocity Vw.

                               Ca
                           A---+---    <=== Vw
                               ¦<--F
                             Hm¦
                             Cm¦
                               ¦Mp
                           ====#====
                               P
What is the expected force F at the top of the mast?
What is the expected moment Mb at the base B of the mast?

Can anybody give me or point me to the proper equations? (metric or
nonmetric units ok)
