Universal Joint

A universal joint, universal coupling, U-joint, Cardan joint, Hardy-Spicer joint, or Hooke's joint is a joint or coupling in a rigid rod that allows the rod to 'bend' in any direction, and is commonly used in shafts that transmit rotary motion. It consists of a pair of hinges located close together, oriented at 90° to each other, connected by a cross shaft.

Famous quotes containing the words universal and/or joint:

    The philosopher is like a man fasting in the midst of universal intoxication. He alone perceives the illusion of which all creatures are the willing playthings; he is less duped than his neighbor by his own nature. He judges more sanely, he sees things as they are. It is in this that his liberty consists—in the ability to see clearly and soberly, in the power of mental record.
    Henri-Frédéric Amiel (1821–1881)

    I learned from the git-go in the joint to get in touch with the soft, nurturing side of myself, the feminine side.
    Wesley Strick, U.S. screenwriter, and Martin Scorsese. Max Cady (Robert DeNiro)
