What Is An Universal JointWhat Is An Universal Joint?

A universal 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.

A u-joint (universal joint) is basically a flexible pivot point that transmits power through rotational motion between two shafts not in a straight line. The u-joint needs to be flexible to compensate for changes in driveline angle due to the constantly changing terrain under the vehicle.

The working of Universal joints has been a mystery to most of the people even though it was invented many centuries ago. This video clearly unveils the physics behind it in a simple and illustrative way with help of animation.
