In some ways tennis has become a truly high tech sport. Advances in racket
design and composition have changed the speed of the game from the days of
wooden frames, and made the game easier and more enjoyable at the recreational
level. Television coverage of matches makes use of sophisticated statistical analysis to explain the outcome of matches in terms of winners, errors, serving percentages and ball placement Players study the statistical tendencies of opponents in an effort to get an edge. But at the most basic level of understanding there is no clear picture of what happens to the tennis ball during the course of a tennis match. The radar guns give us an initial velocity of the serves, but beyond that very little is really known about what happens, when players strike the ball in the game. New types of strikes result in complicated rotation of the ball. For example:
Increasing service speed of ball shooting
Top spin resulting in maximum upper rotation
Slice resulting in simultaneous bottom and side rotation Tennis rackets nowadays need to be constantly re-developed. Design and manufacturing procedures linked with the most essential equipment a tennis player can have, are subjected to aerodynamical change. This book seeks to study tennis from a new perspective – the perspective of design aerodynamics, setting out to determine what we can learn about the flight of the tennis ball. When the ball hits the racket during play, some dynamic stresses and deformations occur with the load periodically changing [1]. This results in oscillations (vibrations) in the racket and under certain conditions the phenomenon “resonance” might occur during which the stress and deformations might suddenly rise to dangerous values. When no resonance conditions exist the periodically changing stress might lead to damages in the racket caused by gradually forming cracks in the material [1].
