Universal Joint:
“… The two-axis universal joint, long known to man and often employed by mechanics as a flexible membrane–sandwiched between two diametrically opposed yoke-ended shafts, with yoke planes symmetrically oriented at 90 degrees to one another–constitute an octahedronal tensegrity, but its shafted axes tend to make it appear as a single-axis system.” (Adapted.)
