Tom- let me stick in my comments- not as an expert on towers, but in
understanding what Kurt said.
1.- his entire set of comments were in the context of the actions that take
place when line stretches.
2. when lines stretch, the longer lines stretch more than the shorter ones.
(ie, the top guy grows more than the lower ones) this is because the
stretch is the same per unit length, and the upper ones are longer.
3. if the top guy has stretched more, the tower is going to try to bend
around the support point of the shorter guy, puting a force TOWARD the
wind, on the base. Imagine what would happen if the upper guy were made of
rubber bands, and the base was on wheels.

W4BSG is "vanity" this time, but was
earned by exam in 1954, the first time.
