Help with deciphering wind loads

  1. Mar 31, 2009 #1
    I have been trying to find answers to this but have had no luck so far.
    I'm hoping these forums can help me out.
    I have some specs for an antenna and need to decipher what the wind loads mean.
    I have attached a picture below.
    Basically, what does the Fa, Fs, and M mean?

    Thank you in advance!

    Hi pcpolo! Welcome to PF! :smile:

    F must mean force (from the wind).

    Looks like the A stands for Axial (ie parallel to the axis), and the S for Sideways.

    I assume M is the moment (in ft lbs). :wink:
