Cardan, Gironde, a commune of the Gironde département, in France
All gearboxes and Cardan (universal) shafts were removed; gears were left in place on the six axles.
Robert Burton (d. 1640) wrote in The Anatomy of Melancholy that "Scaliger and Cardan admire Suisset the calculator, qui pene modum excessit humani ingenii whose talents were almost superhuman".
A universal joint, universal coupling, U-joint, Cardan joint, Hardy-Spicer joint, or Hooke's joint is a joint or coupling in a rigid rod that allows the rod to 'bend' in any direction, and is commonly used in shafts that transmit rotary motion.
