Re: Do we need ropes?

Yes, you are quite right, levering off a strut at 90 deg does not produce a side load and as you continue levering the angle will decrease so that a vertical load is produced, which the tower can absorbe quite happily. However, the struts would have to be quite long (40 feet?) for a 24 foot tower and would need to be moved and re-anchored between each levering operation because they must always act at the fulcrum point in order to achieve the 90 deg requirement.


As I said before, I'm not "against" or "for" any particular method. I think that ALL theories need to be considered and then we reject those which don't stand up to scrutiny. Those that remain are candidates for testing.

I have to go out now, so this will be my last post for a few hours. I'll catch up later.
