isotropic helicoid 3d models

By making the globe and the vanes of light paper, a body is obtained rigid enough and light enough to illustrate by its motions through air the motions of an isotropic helicoid through an incompressible liquid. But curious phenomena, not deducible...

Buckminster Fuller's visionary approach to spatial design now takes center stage as a dynamic, open-source library known as Scad, empowering creatives to explore and harness the full potential of his groundbreaking Isotropic Vector Matrix. This...

... z(t) = 2t/3. ...The parameter u ranges from 0.25 to 1.25, while the parameter t spans from 0 to 2Pi. Both .stl and .form files used for printing are provided. Additional information is available at http://mathvis.academic.wlu.edu/2015/07/27/helicoids/.

The device converts translational motion to rotary motion using a helicoid mechanism similar to a camera lens or mop spinner. Before moving into production, some improvements are necessary: clarifying part dimensions, designing a frame for mounting...

Carbon fiber helicoid tubes, woven in composite form, are the subject at hand.

Stress within isotropic materials is perfectly uniform, exerted equally on all directions and having equal intensity.

... instrument known as a telescope helicoid bolt. ... To adjust your view, keep the eyepiece stationary while carefully turning the helicoid bolt in either direction – this simple action allows you to precisely control the focal length of your device.

This is a model of part of a helicoid with parametric equations x(t)=u.cos(t), y(t)=u.sin(t), and z(t) = 2t/3, where the parameter u varies between -1 and 1. The parameter t ranges from 0 to Pi for the half-twist. ...Additional information is available...

I'm trying to grasp this thing called a "telescope helicoid nut". From what I gather, it's a type of nut used on telescopes, specifically those that use an altazimuth or equatorial mount system. It has threads cut into its surface in a spiral...

This human strut can be used for construction within a space-filling network of continuously alternating octahedra and tetrahedra, known as an Isotropic Vector Matrix. The human figure stands on and supports rhomboid shaped podiums that together...

The internal diameter of the Helicoid Gear Wheel in the Ford Focus's gearbox measures at 31.15 millimeters.

Was looking at Nasa Chainmail and thought to try and attempt making one with the Hexagon Helicoid Tiles for fun, it's very thick.

I've designed a helicoid can carry vintage medium/large format lens. I've used a Topcor lens which were used on horseman field cameras, such as 970, 980 etc. the reason I didn't use the most commonly used Mamiya sekor, simply because they are...

This is a variant of the WillTravel large format cameras (4x5, 5x7, 4x10 or 8x10) with a M65 focus helicoid and not the rotating frontcap in the basic design. This design requires that you know the lens Flange Focal Distance (FFD) with a mm...
