  1. According to USGA equipment rules, what is the maximum Coefficient of Restitution (COR) allowed for a driver face?

    Answer: 0.830

    The USGA limits the COR (spring-like effect) of driver faces to a maximum of 0.830, measuring how efficiently energy is returned from clubface to ball.

  2. What is the maximum number of clubs a golfer is allowed to carry during a round of golf according to the Rules of Golf?

    Answer: 14

    Rule 4.1b of the Rules of Golf limits golfers to a maximum of 14 clubs during a stipulated round.

  3. In custom club fitting, what does 'swingweight' measure?

    Answer: The perceived weight distribution that affects feel during the swing

    Swingweight measures how the club's weight is distributed between the grip end and head end, affecting the perceived heaviness and feel of the club during the swing.

  4. Which shaft material provides the best combination of light weight and high strength for modern performance golf shafts?

    Answer: Graphite (carbon fiber composite)

    Graphite (carbon fiber composite) shafts offer superior strength-to-weight ratios compared to steel, enabling lighter overall club weight that can increase swing speed.

  5. What is the primary function of grooves on a golf club face?

    Answer: To channel away moisture and debris so the face can grip the ball and impart spin

    Grooves channel away moisture, grass, and debris at impact, allowing direct face-to-ball contact that generates friction to impart backspin.

  6. When fitting a golfer for iron shaft flex, what swing characteristic is most commonly used as the primary determining factor?

    Answer: The golfer's clubhead speed or carry distance with a reference club

    Clubhead speed (or distance with a reference club such as a 6-iron) is the primary factor for recommending shaft flex, as faster swingers require stiffer shafts to control ball flight.

  7. According to USGA rules, what is the maximum permitted volume for a driver clubhead?

    Answer: 460cc

    USGA rules limit driver head volume to 460cc maximum, with additional restrictions on face size and other dimensions to control distance.
