Does anyone have a the formula for guy posts? I have a friend that wants tall guy posts (7 feet) for a 100 foot tower so he can walk under them. I need to show him the stress that is involved in that

I've used I-beams for 100ft 45G and 75 ft 25G elevated guys. I needed to drive my tractor under the guys. An engineer is your best bet for the calcs. My I -beams are buried partly (about 4 feet) in c

Why does he want them this high? To do it correctly the post and concrete need to be professionally engineered. According to mechanical engineer K5IU, elevated anchors require many yards of concrete

Well John my cab tractor is about 7'4". I'm in the process of putting up a 70' rohn 45g and have set 8 x 21 beams (8" deep x 21#s per foot) 12' long, 4' down into 3' x 3' x 4' concrete bases to allow

It's a right triangle. Straight trig, but I can never remember which function. It's the side opposite over the hypotenuse or sine is used. So, it's the sin of the angle the guy forms with the anchor

As I mentioned before, I calculated the NW guy post with close to a 10' elevation with a total weight (post, rerod, and concrete, weighs roughly 17,000 pounds. This is for a 100' 45G, guyed at 3 leve

Im pretty sure the 20-foot utility poles in many neighborhoods are not 80 feet long. (Three feet down for every one foot up would be 60 feet buried and 20 feet in the air.) I could see 20/3 (6.66 fee

K4XS said nothing offensive. I think K8RI and W6RMK gave you some indication how to calculate the force on the post. Selecting a structural support of sufficient strength is fairly easy. The base siz
