Golf ball A golf ball next to a holeEnlarge picture A golf ball next to a hole A golf ball is a ball designed to be used in the game of golf. A regulation golf ball weighs no more than 1.620 oz (45.93 grams), with a diameter over 1.680 in (42.67 mm), and is symmetrically spherical in shape. Like golf clubs, golf balls are subject to testing and approval by the Royal and Ancient Golf Club of St Andrews and the United States Golf Association, and those that do not conform with regulations may not be used in competitions (Rule 5-1 — also see rules of golf). History Wooden balls were used until the early 17th century, when the featherie ball was invented. This added a new and exciting feature to the game of golf. A featherie is a hand sewn leather pouch stuffed with goose feathers and coated with paint. The feathers in the ball were enough to fill a top hat. They were boiled and put in the cowhide bag. As it cooled, the feathers would expand and the hide would shrink, making a compact ball. Due to its superior flight characteristics, the featherie remained the standard ball for more than two centuries. However, an experienced ball maker could only make about two in one day, so they were expensive. A single ball would cost between 2 and 5 sterling, which is the equivalent of $150 and $400 today. Also, it was hard to make a perfectly spherical ball, and because of that, the ball often flew irregularly. When playing in wet weather, the stiches in the ball would rot, and the ball would split open after hitting a hard surface. In 1848, the Rev. Dr. Robert Adams (or Robert Adam Paterson)[1] invented the gutta-percha ball (or guttie). The gutta was created from dried sap of a Sapodilla Tree. The sap had a rubber-like feel and could be made round by heating and shaping it while hot. Accidentally, defects in the sphere proved to have a truer flight than pure spheres. Thus, makers started creating intentional defects in the surface to have a more consistent ball flight. Because gutties were cheaper to produce and could be manufactured with textured surfaces to improve their aerodynamic qualities, they replaced feather balls completely within a few years. 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 idea was first discovered by Coburn Haskell of Cleveland, Ohio in 1898. Haskell drove to nearby Akron to keep a golf date with Bertram Work, then superintendent of B.F. Goodrich. While he waited for Work at the plant, Haskell idly wound a long rubber thread into a ball. When he bounced the ball, it flew almost to the ceiling. Work suggested Haskell put a cover on the creation, and that was the birth of the 20th century golf ball. The design allowed manufacturers to fine-tune the length, spin and "feel" characteristics of balls. Wound balls were especially valued for their soft feel. Today's golf balls have progressed into having cores of titanium compounds, hybrid materials, softer shells and a more pressurized core. They usually consist of a two-, three-, or four-layer design, (named either ; a two-piece, three-piece or a four-piece ball) consisting of various synthetic materials like surlyn or urethane blends. They come in a great variety of playing characteristics to suit the needs of golfers of different abilities. Regulations The diameter of the golf ball cannot be any smaller than 1.680 inches. The maximum velocity of the ball may not exceed 250 feet per second under test conditions and the weight of the ball may not exceed 1.620 ounces. Aerodynamics When a golf ball is hit, the impact which lasts less than a millisecond, determines the ball’s velocity, launch angle and spin rate, all of which influence its trajectory (and its behavior when it hits the ground). A ball moving through air experiences two major aerodynamic forces, lift and drag. Dimpled balls fly farther than non-dimpled balls due to the combination of two effects: Firstly, the dimples delay separation of the boundary layer from the ball. Early separation, as seen on a smooth sphere, causes significant wake turbulence, the principal cause of drag. The separation delay caused by the dimples therefore reduces this wake turbulence, and hence the drag. Secondly, backspin generates lift by deforming the airflow around the ball, in a similar manner to an airplane wing. This is called the Magnus effect. Backspin is imparted in almost every shot due to the golf club's loft (i.e. angle between the clubface and a vertical plane). A backspinning ball experiences an upward lift force which makes it fly higher and longer than a ball without spin.[1] Sidespin occurs when the clubface is not aligned perpendicularly to the direction of swing, leading to a lift force that makes the ball curve to one side or the other. Unfortunately the dimples magnify this effect as well as the more desirable upward lift derived from pure backspin. (Some dimple designs are claimed to reduce sidespin effects.) In order to keep the aerodynamics optimal, the ball needs to be clean. Golfers can wash their balls manually, but there are also mechanical ball washers available. Design These two balls are disclosed in U.S. Patent 4,560,168 . These two balls are easily made with a two-piece mold. Since there is no dimple located on any of the slash-dotted circles (one is marked red), the mold can be two hemispheres.Enlarge picture These two balls are disclosed in U.S. Patent 4,560,168. These two balls are easily made with a two-piece mold. Since there is no dimple located on any of the slash-dotted circles (one is marked red), the mold can be two hemispheres. Most golf balls on sale today have about 300 - 450 dimples. There were a few balls having over 500 dimples before. The record holder was a ball with 1,070 dimples -- 414 larger ones (in four different sizes) and 656 pinhead-sized ones. All brands of balls, except one, have even-numbered dimples. The only odd-numbered ball on the market is a ball with 333 dimples, called the Srixon AD333. Officially sanctioned balls are designed to be as symmetrical as possible. This symmetry is the result of a dispute that stemmed from the Polara, a ball sold in the late 1970s that had six rows of normal dimples on its equator but very shallow dimples elsewhere. This asymmetrical design helped the ball self-adjust its spin-axis during the flight. The USGA refused to sanction it for tournament play and, in 1981, changed the rules to ban aerodynamic asymmetrical balls. Polara's producer sued the USGA and the association paid US$1.375 million in a 1985 out-of-court settlement. The United States Patent and Trademark Office's patent database is a good source of past dimple designs. Most designs are based on Platonic solids such as icosahedron. Golf balls also come in different colors, which helps with finding the ball when lost or in distinguishing one player's ball from any other players' balls. White is the most common color. Hexagonal Dimples Some of the new technological advances in a golf ball have hexagonal dimples. This new technology enables the ball to have less drag than the normal dimpled golf balls. The balls have variations on the size of the dimples and also some have deeper dimples than others, Callaway Golf is the main supplier of the hexagonal design golf balls, such as the Callaway HX. Selection There are many types of golf balls on the market, and customers often face a difficult decision. Golf balls are divided into two categories: recreational and advanced balls. Recreational balls are oriented toward the ordinary golfer, who generally have low swing speeds (80 miles per hour or lower) and lose golf balls on the course easily. These balls are made of two layers, with the cover firmer than the core. Their low compression and side spin reduction characteristics suit the lower swing speeds of average golfers quite well. Furthermore, they generally have lower prices than the advanced balls. Advanced balls are made of multiple layers (three or more), with a soft cover and firm core. They induce a greater amount of spin from lofted shots (wedges especially), as well as a sensation of softness in the hands in short-range shots. However, these balls require a much greater swing speed that only the physically strong players could carry out to compress at impact. If the compression of a golf ball does not match a golfer's swing speed, either the lack of compression or over-compression will occur, resulting in loss of distance. There are also many brands and colors to choose from, with colored balls and better brands generally being more expensive, making an individual's choice more difficult. Trick Balls A number of designs of novelty ball have been introduced over the years, mainly as practical jokes for the amusement of fellow golfers, but also as "cheater" balls that do not conform to the Rules of Golf. All of these are banned in sanctioned games, but can be amusing in informal play: * Breakaway balls are brittle and hollow, and shatter into many small pieces when hit. * Exploding balls are similar, but employ a small explosive device that disintegrates the ball when hit. Many courses have banned these as the charge can damage the turf, the player's club or even cause injury, leading manufacturers to develop the breakaway. * Stallers are far softer than a normal golf ball, allowing them to be compressed far more easily and are given greater backspin when hit. Both of these give the ball a huge amount of lift, making shots climb very high into the air with very little distance travelled over the ground. In the right conditions, such a ball may travel backwards along its flight path or even perform a loop-the-loop. * Sponge balls are softer still; they are generally used as indoor or backyard practice balls, but some are deceptively similar in appearance to a normal ball. Such a ball will travel less than a quarter of the distance of a normal golf ball. * Wobblers have a center of mass that is not in the exact center of the ball or is loose within the ball. When putted, the ball will move unpredictably off the intended line. * Floaters are less dense than a regulation golf ball so when hit into a water hazard, they bob on the surface when a normal ball would sink. * Super-distance balls have deeper dimples and are heavier than allowed by regulation, which allows them first to maintain momentum and second to maintain a thicker "envelope" of still air around them which reduces turbulence and wind resistance. Marketers of these balls generally advertise a 12-yard gain on most distance shots.
