Strings (tennis)
The material used in tennis string can significantly affect a player's performance, and even health. Several materials are used to make tennis strings. They vary in terms of elasticity, durability, rebound efficiency, tension holding capability, and manufacturing cost, among other considerations.
String (structure)
In music, a string is the vibrating element that produces sound in string instruments such as the guitar, harp, piano (piano wire), and members of the violin family. Strings are lengths of a flexible material that a musical instrument holds under tension so that they can vibrate freely, but controllably. Strings may be "plain" (consisting only of a single material, like catgut, nylon, or steel). "Wound" strings have a "core" of one material, with an overwinding of other materials. This is to make the string vibrate at the desired pitch, while maintaining a low profile and sufficient flexibility for playability.
