USRSA MEMBERSHIPS

The United States Racquet Stringers Association is an organization dedicated to supporting professional and private racquet stringers with educational and resource materials that include a yearly stringer's digest, a monthly magazine (RacquetTech), and an interactive web site. The USRSA also offers a certification program that is the recognized standard of excellence for racquet stringers and racquet technicians. Silent Partner supports the USRSA and recommends that all enthusiast with an interest in tennis equipment (racquets, strings, stringing machines, stringing technique, etc.) consider joining the organization. The cost of a one year membership is $109 or less, and this gives access not only to a wealth of authoritative information about racquet and string technology, but also to material benefits such as free marketing samples of products like strings and grips. Though the free samples help offset the cost of membership, Silent Partner believes that the educational resources offered by the USRSA more than justify the cost of membership. For this reason, Silent Partner offers the service of accepting membership requests on behalf of the USRSA.

The Physics and Technology of Tennis

"The Physics and Technology of Tennis is the most important tennis book in fifteen years..." --Vic Braden

Professors Howard Brody and Rod Cross, the top two experts on the physics of tennis in the world, join forces with Racquet Tech magazine's technology expert, Crawford Lindsey, to lead readers on a mind-expanding adventure covering everything players, coaches, stringers, retailers and teaching pros ever wanted to know about tennis equipment and how it affects performance!

The life's purpose of a tennis racquet is to change the speed and direction of a tennis ball. This momentous event takes place in approximately five one-thousandths of a second. During that time, the ball and the racquet launch into a frenzy of technology-enhanced physics:

• The strings stretch, deflect, vibrate, store and return energy.
• The ball squashes, slides, bites, reverses direction, ejects, and flies away like vibrating jello.
• The racquet decelerates, rotates, bends, twists and vibrates.
• Bending waves race up and down the racquet, slamming the handle into the hand.

• Pain, frustration, anger, joy, or elation explode forth from the collision.

Players paying upwards of $300 per racquet and $50 for restringings can spend hundreds of dollars every year trying to influence any of these events in their favor. This book explains the what, how and why of those fateful collisions on each side of the net, as well as the flight and the bounce of the ball in-between.
