In the two-dimensional case, the top and bottom pieces are one-dimensional lines. In the three-dimensional case, the top and bottom pieces are two-dimensional planes. So in the four-dimensional case, the top and bottom pieces will be three-dimensional solids. For simplicity, think of them as tetrahedra, with the four "stabilizer" cables being attached to the four vertices of each tetrahedron in pairs, and the single "support" cable being attached to some sort of outriggers corresponding in some way to the centers of the tetrahedra in such a way that pushing the tetrahedra towards each other tensions that support cable. I can't visualize that outrigger, but, then again, neither can you. ;-)

For those wanting to know how to generalize it to n dimensions: If you generalize, in 2D the table top is a 1D segment, in 3D its a 2D plane, in 4D it would be a 3D hyperplane. You can project the tabletop only and visualize it as a cube or a ball depending on your artistic choice for the table. In 2D, the outer cables are attached at two points. Their position is trivial. In 3D, the outer cable are attached in a triangular pattern. In 4D, the outer cable would be attached in a tetrahedron, the generalization of a triangle. You can visualize the ball or cube of your tabletop and the 4 anchor point arrange in a tetrahedron inside of it. Now, the cable themselves extend in the direction perpendicular to the table top. In 2D, it's just the only axis perpendicular to the axis of the tabletop. In 3D it's the only axis normal to the plane of the tabletop. In 4D, its the forth axis that isn't part of the cube or ball we projected on our 3D space. There no real way of visualizing it, but you can imagine it to link the table top to the base support which is exactly the same shape with the same anchor point, only shifted in the direction of the 4th axis (think of the analog thing in the 3D table, where the base has the same shape as the top but at a different position). Finally, the center cable, when viewed from the top in the 3D case, is attached in the center of the table top. View from the side, it extends somewhere between the tabletop and the base. In 4D, it would be attached "below" the cube, in the 4th axis direction, and below the center of the ball or the cube. In general, in nD, you would have an (n-1)D tabletop and base, with n cables attached at each vertex of an (n-1)D simplex (the generalization of a triangle), and the center cable would be attached somewhere "below" the center of the simplex.

I think this isn't tensegrity by the strict definition, because the posts in the middle have a curve and there's both tension and compression with the same piece of metal. By the strict definition tensegrity structures are made with only straight poles that are loaded in compression along their length and wires in tension.
@susanlowelldesolorzano96239 ай бұрын
Look up Kenneth Snelson, who worked with Buckminster Fuller, or Georges Emmerich; both devised tensegrity independently. Fuller invented the word. We study it in biology: biotensegrity. see the BiotensegriTea Party episodes here on youtube for more info.

@@DOC_951 Look at the Wikipedia page. "members loaded in either pure compression or pure tension, which means that the structure will only fail if the cables yield or the rods buckle." ... "Because of these patterns, no structural member experiences a bending moment and there are no shear stresses within the system". In the structure in this video the two curved members in the middle, as well as the round discs at top and bottom, clearly experience bending moments.

@@yeroca 4d, once again, is a temporal (time) dimension, not spatial. When you see 3d objects change, age, move, etc. That object is in the 4th dimension. So to answer your question how about a 4th spatial dimension...no. or better yet, you explain it to me.
@yeroca8 ай бұрын
@@seanrobinson6407 Um, so,. you can define a theoretical space (not our three-spatial dimension case) as having as many spatial dimensions as you like... at least mathematically. You can mathematically describe objects in higher dimensional spaces, and then project them down to 3D or 2D spaces to get some feeling about what they are like. The objects are typically called "hyperX", for example, a cube in four dimensions is called a hypercube. In String theory, space has a lot more than three spatial dimensions, but the spatial dimensions outside the three that we are familiar with are bound up like loops and are incredibly tiny.
@seanrobinson64078 ай бұрын
@@yeroca um, so... You need to get a few things straight. 1 d is represented as a dot, 2d is represented as a line, 3d is space in all directions often represented as a cube. 4d is those spatial dimensions moving through the temporal dimension of time. A time line. Space time. Get it? There are dimensions above 4d, some of which are theoretical which is what I think you were attempting to describe. I didn't make up or determine any of them. My original statement was that they made a 3d object in the 4th dimension of time. Which is completely pedestrian, as we all do that. You exist in 4d. There are books and websites that will explain dimensions to you, and perhaps then you will accept that we live in 4d which is space moving through time. I don't know what else to tell you.

The main point is, the weight is being borne by the middle wire. That's why the two arms curve round, so the top arm can dangle from the bottom one. The other 3 wires just stop it from toppling over. Technically if you could balance it absolutely perfectly, you'd only need the middle wire. Not in practice, but in theory.
@pocketsfullofdynamiteАй бұрын
I think if a spring was used to do the same if the middle spring doesn't stretch further down it won't let the structure fall down. Though the use of stretchable string looks magical.

I think the thing that is probably confusing people the most is not realizing the tension was adjusted to make all this work properly. I think the natural inclination is yeah if you pull the middle string tight then the outer ones will go slack. The string in the middle is under so much tension that it cannot let the top part fall and yet the outer ones are still taught. It must take a lot of adjusting to get this tension just right.

The way i see it, the bottom of the top part hangs from the little string attached to the top of the bottom part. Strings in the periphery centers it.
