So, I take that you've folded up a boom trying to lift something? Can
we assume that you learned nothing from it, other than "don't"?

Such vivid imagination.

Well, I have seen booms supported by rigid vangs that didn't fold up, so
obviously it can be done... if you do it right.

You think it can't be done, why? Conclusion: you did it wrong, and
decided it was impossible.


.... it's obvious from this
thread to any engineer that you don't even begin to understand basic
engineering.

Funny you should say that, since you show no comprehension of how to
read the diagram, yet you pass judgement on my competence. The
resolution of forces is not obvious but it's also not rocket science.

If OTOH you *do* have some clue what you're talking about, tell us what
the mysterious symbol next to the mast represents.
