Stresses in Universal Knuckle Joint Formulas and Calculator

Stresses in Universal Knuckle Joint. Universal joints are a mechanical form of coupling, originally known as a Cardan or Hooke's coupling, is used for connecting two shafts the axes of which are not in line with each other, but which merely intersect at a point. There are many different designs of universal joints or couplings, which are based on the principle embodied in the original design.
