A "Hookes joint" is a mechanical device that connects two rotating shafts in a system, allowing for angular movement and transmitting torque. Commonly known as a universal joint, this device is utilized in various applications, such as automobiles and industrial machinery. Synonyms for a Hookes joint include "Cardan joint", "universal coupling" or "U-joint". All these terms refer to the same mechanism, emphasizing its capability to transfer rotational force while accommodating angular displacement. While the exact name may vary, the fundamental purpose remains unchanged, providing flexibility and smooth transmission between rotating components in diverse mechanical systems.
