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.
Basic physics of the violin
String tension affects the sound a violin produces in an obvious way. Increasing the tension on a string results in a higher frequency note. The strings of a violin are wrapped around adjustable tuning pegs. By turning its associated peg, each string may be loosened or tightened until it produces the desired pitch, which may be described in terms of frequency. The playing tension of a violin string ranges from about to .
