Could you double-check my use of on-line calculators to determine the
column buckling load of a pinned-end chain link fence post 1.90" OD,
1.77" ID (16 gauge) and 96" long as 4900 lbs?

I get ~1600 lb and that's assuming fully axial loading with no
moment...will be significantly less with side loading. Seems on first
blush at a reasonable number, 8'L/2"D is a pretty long and slender
wand...and 16 ga ain't that stout.

Oh, crud...I had a typo and missed a factor of pi....the Euler formula
does say 4900. I'm surprised it's that high; the other number surely
doesn't seem out of line.
