A universal joint is a mechanical part that connects two shafts, allowing them to rotate at different angles while transmitting power. It is commonly used in vehicles, bicycles, and some sports equipment where flexible movement is needed. The joint helps transfer motion smoothly even when the connected parts are not perfectly aligned, reducing stress on the system. It is often found in steering systems, drive shafts, and other moving parts that require flexibility.
