Did you think about how you support the cables ? Surely they must be tensionned or else they will hang. How do you tension them ?Mechanical advantage. The booster weighs 250 tons. A 40' shipping container has a max payload of about 30 tons. There are cranes that can lift 250 tons, and it won't be one, but many. Have you seen gantry cranes?
>So you need a big-ass structure to hold all of these cables.
Similar to the big-ass structure holding the 250 ton booster with the T-Rex arms?
>They must be able to circulate around the perimeter, while being in tension, while not collapsing the structure that holds them, etc..
Not circulate, but translate. The cinching in is a result of them translating. Again, see cranes and gantry cranes. Or, just see the actual chopsticks: circulating, not collapsing the structure that holds them, while being in tension, holding the booster at the free end.
Are you seeing the shear and moment diagram of that cantilever beam with point load? (I know, it's an extension of a supported beam, but still cantilever).
>I'm sure you think it's easy
I'm not sure I think it's easy, I can't see how you're more sure than I about my own thoughts.
>but I'm sure some people thought a bit more
You are people, too. Nothing prevents you from thinking as well, if for nothing than to have a civil conversation on a forum.
Now, that's all fun. Imagine they keep it the way it is, but they duplicate the setting to make a circle, so the booster lands in the middle of many chopsticks... What do you think about that?
