Hi, Barry --
What about my other statements? I was hoping that someone would be able
to address the more esoteric forces and calculations of the cable vis-a-vis
tower load. Not being an engineer I never knew the integral calculus to
forget it in the first place. I'm sure that there are some fluid dynamics
involved or section modulus or other things that I don't even know about.
Can anyone shed any light on this topic? Inquiring minds want to know.
