History Of Golf Balls
by Acario Daire
1. Until the early17th century, People used wooden
balls for playing golf. Then the Featherie ball was invented. A
Featherie is a hand sewn cowhide bag stuffed with goose feathers
and coated with paint. The Featherie remained the standard Golf
ball for more than two centuries, due to its superior fight
characteristics.
2. In 1848, Robert Adam Paterson invented the Gutta
Percha ball. Gutties had textured surfaces to improve their aerodynamic
qualities and where also cheaper to produce. They only replaced
feathered balls completely within a few years.
3. In the 20th century, multi layer balls were developed,
first as wound balls consisting of a solid or liquid-filled core
wound with a layer of rubber thread and a thin outer shell. This
design allowed manufacturers to fine-tune the length, spin and "feel"
characteristics of balls. Wound balls were especially valued for
their soft feel.
4. These days golf balls are made of cores of titanium
compounds, hybrid materials, softer shells and a more pressurized
core. They usually consist of a two-three, r four layer designs,
consisting of various synthetic materials like surlyn or urethane
blends.
Characteristics of Modern Golf
Balls
- The minimum of allowed diameter of golf
ball is 42.67mm and its mass may not exceed 45.93g.
- Modern golf balls have a two, three, or four
layer design constructed from various synthetic materials.
- The surface of the ball usually has a pattern
of 300-400 dimples designed to improve the balls aerodynamics.
- Materials and the method of construction used
greatly affect the ball's paying characteristics such as distant
trajectory, spin and feel.
- Harder materials such as surlyn are used, which
result in ball's traveling longer distances.
- Softer covers such as balata tend to generate
higher spin, more "feel" and greater stopping potential.
Golf balls are separated into 3 groups depending on their construction
two, three, or four-piece covers generally four-piece golf balls
tend to be the most expensive but price is no assurance of quality.
Golf Ball Aerodynamics
When we hit a golf
ball, the impact which lasts less than a millisecond, determines
the ball's velocity. Launch angle and spin rate, all of which influences
its trajectory.
A ball moving through air experiences two major
aerodynamics forces.
1. lift
2. drag
Drag slows the forward motion. Whereas lift acts
in a direction perpendicular to it. The magnitude of these forces
depends on the behavior of the boundary layer of air moving with
the ball surface.
Dimples are designed to increase the shape and
lift and drag forces by modifying the behavior of the boundary layer.
It should be noted that drag and lift forces exists also on smooth
balls. Dimpled balls fly farther than non dimpled balls due to the
combinations of two effects.
The backspin as we discussed before generates the
lift by deforming the airflow around the ball. A back spinning ball
experiences a upward lift.
The order to keep the aerodynamics optimal, the
ball needs to be clean; golfers can wash their balls manually. Mechanical
ball washers available.
