How does string pattern affect racket performance?

What happens to power, maneuverability, shock, and spin when the string pattern on a racket becomes denser?

Choose the correct answer:

a) Power increases and spin decreases, shock remains the same

b) Power decreases and spin decreases, shock increases

c) Power increases and spin increases, shock remains the same

d) Power decreases and spin decreases, shock decreases

Answer:

Option b) Power decreases and spin decreases, shock increases

As the string pattern becomes denser, power decreases because a denser string pattern results in a higher string bed stiffness, which means the strings have less elasticity to rebound the ball (a 'trampoline effect'). This is analogous to a stiffer diving board having a shorter period of vibration compared to a more flexible one. Consequently, the ball will not launch as powerfully from a denser string bed as it would from a more sparse one.

Maneuverability is not directly answered by the information given, but a denser string pattern could affect the swing weight of the racket, potentially impacting maneuverability.

Shock is increased because the higher string bed stiffness created by the denser string pattern transfers more impact force to the player, similar to how a less cushioned surface, like tile compared to carpet, transmits more force during a collision.

Spin is reduced because denser strings offer smaller gaps for the strings to 'bite' into the ball, making it harder to impart heavy spin.
