A tennis racquet has one of its regular strings replaced with a very thin wire strain 6) gauge. Assume the gauge is made from a tungsten wire with a gage factor of 4. Upon impact with a tennis ball, the strings stretch somewhat, and the center of the string web is displaced 1 cm out of the plane of the racquet. The diameter of the racquet head is 25 cm. a) b) What is the percentage resistance change in the wire when the ball is hit? Would you expect the wire to break?
