DESCRIPTION OF THE FAILED COMPONENT
A lyre is typically a single piece of metal tubing (usually copper or stainless steel) that has been mechanically bent into a loop or "S" shape. In this sense, it differs from a hose, which is a composite flexible tubing, consisting of more layers, and designed to be moved and bent repeatedly.
