I need some help from the more structurally-oriented members of our
fraternity.
I need to know if it is practical to erect a 75-foot vertical element from
aluminum tubing that has the following dimensions:
OD: 1.785"
ID: 1.57"
Wall: 0.11"
Length: 48" overall; 3.25" suaged and shouldered to fit into the next
section
Weight: 2.7lb
I have devised a raising fixture that has allowed me to raise 45ft masts of
this material alone and with ease. Will a 75ft element stand up, or is there
serious risk of it buckling under its own weight? Of course, numerous guy
levels will be needed - I'm planning on 5.
Thanks,
Brian K1LI
