mechanical failure. In an ideal world, all the racket are seeking to maximize these indicators, and ultimately choose the power and control as the design of the most important indicators. 2.1 Strength of a design principle is "for greater strength, using a network cable." Cable able to reply after impact deformation energy of about 90%, while the individual balls (rebound on the hard surface) only 45% of the response energy (Brody, 1995). Further, the racquet frame deformation energy is not respond promptly to the ball, the ball increase energy, means any of a maximum degree of deformation of the racket when receiving a shock generated by the network cable, or deformation of the frame than the tennis ball is more increased power. In the 1970s, in the event of large racket, they began to restrict the use of the principle of network cable size bed. The current principle established by mass and width of the maximum network Tennis ball manufacturers, Tennis ball wholesale, www.tennis-ball-manufacturers.com
