Slim and graceful, Kenneth Snelson's Needle Tower stretches 60 feet into the sky. The structure looks too delicate to stand so tall, but it's strong enough to withstand severe storms. Erected in 1968 beside the Hirshhorn Museum and Sculpture Garden on the National Mall in Washington, D.C., this tapered framework of aluminum tubes and stainless-steel cables is an example of a tensegrity structure. The tubes aren't connected to each other. Instead, cables thread through the tubes to hold the assemblage together in perfect balance. Snelson discovered the underlying principle for such structures in 1948, advocating the term "floating compression" to describe the balance between tension and compression and, in his sculptures, between flexible cables and rigid tubes. R. Buckminster Fuller (1895-1983) coined the word "tensegrity" (combining "tension" and "integrity") for the same idea, and his term stuck. Snelson refers to weaving as the "mother of tensegrity." Snelson defines "tensegrity" as follows: "Tensegrity describes a closed structural system composed of a set of three or more elongate compression struts within a network of tension tendons, the combined parts mutually supportive in such a way that the struts do not touch one another, but press outwardly against nodal points in the tension network to form a firm, triangulated, prestressed, tension and compression unit." Snelson's Needle Tower delivers a wonderful geometrical surprise when you venture underneath and look up to see a striking pattern of six-pointed stars. This pattern arises naturally out of the requirement that each layer of a tensegrity structure consist of three compression elements (tubes). The sets of three alternate, giving the impression of a six-pointed star as you look up the tower. Snelson's sculptures often show this kind of symmetry. The elegance of Snelson's tower suggests its use as an aesthetic alternative to conventional communications towers. But tensegrity structures are fairly elastic and flexible. They sway in the wind, which may not be ideal for the antennas and dishes that would top such structures. Needle Tower recently required some conservation work. A video shows a crew of museum exhibit staff raising the repaired sculpture back into place on Hirshhorn Plaza, clearly demonstrating the structure's strength and flexibility. Photos by I. Peterson

< PREVIOUS MAIN The final step in setting up the tensegrity tower is in adjusting the diagonal cables to level the structure and make it symmetrical. After the previous post, your tower should look something like the tensegrity above, but will probably not be very tidy- there might be poles touching each other, the lower deck is probably squashed under the weight of the decks above. Again, working methodically around the structure from bottom to top and in the same direction on each deck, tighten the diagonal ropes. You will quickly get an idea for how they interact with each other. Don't be scared to tighten the lower decks by quite a lot to get the tower standing straight. When the tower is leaning in one direction (like this one is: in fact just outside the photo Ross is holding a string to stop this from falling over) This is a close-up showing how the bottom deck has collapsed, with all poles touching at least one other pole. Tightening the diagonals will fix this. Ideally, you can tighten the diagonals on opposite sides at the same time- if two people work on the tower, this is pretty easy. Another kind of failure that can happen if you are not careful is that the mounting loops at the ends of the poles can come untied- what normally happens is that your structure will either collapse completely or you will end up with a rope running up onto one of the other ropes- like this one has. Loosen the diagonal and carefully re-tie the loop. After a couple of passes around the structure, you should be happy with the symmetry. All that is left now is to place your tower where you want it. There is a little trick here: if you CAREFULLY untie one diagonal in each layer, you can actually bundle your tensegrity up into a small roll like this: Which is exactly what we did, so that we could set it up in the pond. We decided that because the tensegrity tower is so light, we wanted to float it in the pond outside the Architecture building. To do this, we simply placed a 2 litre soft drink bottle onto each leg of the bottom deck, as shown in this photo. We then tied the one leg of the tower to the pipe for the water fountain in the pond, so that it would not float to the edges of the pond. And that's that! The tower the night we installed it. After a few weeks, the cane started to buckle, and the tower would no longer stand. We laid it on it's side and moved the bottles around to turn it into a 'bridge' (By the way, you ca nget a clue for the weight of the structure: 4 2 litre bottles will float at most an 8 kilogram structure, so this tower must have been lighter than that). NEXT: review of all the tensegrity posts, links to sites, other examples.
