Universal Joint

A universal joint, also known as a universal coupling, U-joint, Cardan joint, Hardy-Spicer joint or Hooke's joint, is a component in a rigid rod that permits the rod to bend in any direction. It's commonly used in shafts transmitting rotary motion, featuring two hinges positioned closely together and oriented at 90° to each other, connected via a cross shaft. However, it doesn't guarantee constant velocity.
