I have been asked to design a flag pole, 250' tall for a flag pole for a flag 50 feet long. heres the kicker, he wants to use old W shapes to make the pole, and have them cut to be tapered to make this thing. I am at a loss how to design this. Anyone ever done this before?
 
I liked the part about "moving it around". :)

You had me going until then!
 
I just did a little sign footing (4x8 sign), and the results always seem like April's fool - Two 4x4 wood posts each with 24" dia x 4'-2" deep footing - that formula for post footings where there is no restraint at the top.

The drawing, to scale, looks out of proportion - comparing wood post to ftg.

The definition of a structural engineer: overdesign by a factor of 1.999, instead of the usual 2.
 
I always seem to get un-intutive numbers when I use the post footing formulas.
