Early ideas of universal joints (or U-joints) have dated back thousands of years and seem to originate from multiple sources. However, about a century ago, a young engineering graduate, Clarence W.

Universal joints, or U-joints, are used to join shafts that must intersect at angles greater than those that can be accommodated by flexible couplings. Universal joints, or U-joints, are used to join ...

Why do we have to think about these angles at all? We wouldn't if the engine, transmission, driveshaft, and pinion all shared the same centerline. As it is, these components are never on the same ...
