A Rzeppa-type CV joint. A constant-velocity joint (also called a CV joint and homokinetic joint) is a mechanical coupling which allows the shafts to rotate freely (without an appreciable increase in friction or backlash) and compensates for the angle between the two shafts, within a certain range, to maintain the same velocity.
Joint cracking is the manipulation of joints to produce a sound and related "popping" sensation. It is sometimes performed by physical therapists, chiropractors, and osteopaths [1] pursuing a variety of outcomes. The cracking of joints, especially knuckles, was long believed to lead to arthritis and other joint problems.
Unlike the Hooke's type universal joint which has a sinusoidal output, the Thompson coupling is a true constant velocity joint. Reference: cvcoupling.com - Simon Purser This page should not (just) give so much background about the automotive application, this is just an application and this article is about the CV joint itself.
Crepitus is "a grating sound or sensation produced by friction between bone and cartilage or the fractured parts of a bone". Various types of crepitus that can be heard in joint pathologies are: Bone crepitus: This can be heard when two fragments of a fracture are moved against each other.

In geotechnical engineering, a discontinuity (often referred to as a joint) is a plane or surface that marks a change in physical or chemical characteristics in a soil or rock mass. A discontinuity can be, for example, a bedding , schistosity , foliation , joint , cleavage , fracture , fissure , crack, or fault plane.
Vibration isolation of supporting joint [ edit ] The equipment or other mechanical components are necessarily linked to surrounding objects (the supporting joint - with the support; the unsupporting joint - the pipe duct or cable), thus presenting the opportunity for unwanted transmission of vibrations.
