You can't really predict the center of mass of a table, so it makes sense to have wire on all 4 sides. You don't want the table to collapse when someone puts too much weight on one side of the table. I think adding a third or forth cable in the middle would also increase the stability.
No, or maybe yes. It depends on how much force and in which direction. And how much downward force is on the table. Its like leaning back in a chair. A little is OK but a lot is embarrassing.
Not if the wires are straight up and down. When the wires are at an angle they are able to apply sideways loads to the table and it is these loads that stop the oscillation. The trick is to balance the side loads so the table doesn't move sideways. This is easy when the wires are splayed, each leg of the splay exactly answers the side forces of the other leg. This can also be done with wires that are separated but it gets more complicated. Now both side loads and torque need to be balanced. It should be doable, best way to learn is to build.
Thanks for sharing I like the explanation of the physics behind this seemingly impossible piece of art
I'm glad to help!

Yeah, its a tradeoff between usability and looks. You would need the more stable design in a public use area.
Hi, nice video. I have a question. In case of a tensegrity table, will it collapse if we give tangential force on the table top?
No, or maybe yes. It depends on how much force and in which direction. And how much downward force is on the table. Its like leaning back in a chair. A little is OK but a lot is embarrassing.
Thanks for the explanation! If you have a design with several wires along the perimeter, do you think that would negate the need for splayed wires?
