A golf club is a club used to hit a golf ball in a game of golf. Each club is composed of a shaft with a grip and a club head. Woods are mainly used for long-distance fairway or tee shots; irons, the most versatile class, are used for a variety of shots; hybrids that combine design elements of woods and irons are becoming increasingly popular; putters are used mainly on the green to roll the ball into the hole. A set of clubs is limited by the rules of golf to a maximum of 14 golf clubs, and while there are traditional combinations sold at retail as matched sets, players are free to use any combination of legal clubs. The most significant difference between clubs of the same type is ''loft'', or the angle between the club's face and the vertical plane. It is loft that is the primary determinant of the ascending trajectory of the golf ball, with the tangential angle of the club head's swing arc at impact being a secondary and relatively minor consideration (though these small ch ...

Wood (golf)
A wood is a type of golf club, club used in the sport of golf. Woods have longer shafts and larger, rounder heads than other club types, and are used to hit the golf ball, ball longer distances than other types. Woods are so called because, traditionally, they had a club head that was made from hardwood, generally Persimmon#Wood, persimmon, but modern clubs have heads made from metal, for example titanium, or composite materials, such as carbon fiber. Some golf enthusiasts refer to these as "metals" or "metal woods" but this change in terminology is not strictly necessary, because while the material has changed, the style and intended use has not. The change to stronger materials has allowed the design of the modern woods to incorporate significantly larger heads than in the past. Because of the increase in club head size, in 2004, the USGA created a new stipulation for the size of the club head. The legal maximum volume displacement of any clubhead (by the rules of golf) is Woo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron (golf)
An iron is a type of club used in the sport of golf to propel the ball towards the hole. Irons typically have shorter shafts and smaller clubheads than woods, the head is made of solid iron or steel, and the head's primary feature is a large, flat, angled face, usually scored with grooves. Irons are used in a wide variety of situations, typically from the teeing ground on shorter holes, from the fairway or rough as the player approaches the green, and to extract the ball from hazards, such as bunkers or even shallow water hazards. Irons are the most common type of club; a standard set of 14 golf clubs will usually contain between 7 and 11 irons, including wedges. Irons are customarily differentiated by a number from 1 to 10 (most commonly 3 to 9) that indicates the relative angle of loft on the clubface, although a set of irons will also vary in clubhead size, shaft length, and hence lie angle as the loft (and number) increase. Irons with higher loft than the numbered iro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golf Ball
A golf ball is a ball designed to be used in golf. Under the rules of golf, a golf ball has a mass no more than , has a diameter not less than , and performs within specified velocity, distance, and symmetry limits. Like golf clubs, golf balls are subject to testing and approval by The R&A (formerly part of 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)''. History Early balls It is commonly believed that hard wooden, round balls, made from hardwoods such as beech and box, were used for golf from the 14th through the 17th centuries. Though wooden balls were no doubt used for other similar contemporary stick and ball games, there is no definite evidence that they were actually used in golf in Scotland. It is equally likely, if not more so, that leather balls filled with cows' hair were used, imported from the Netherlands from at least 1486 onwar ...

Sand Wedge
A sand wedge, or sand iron, is a type of golf club, an open-faced wedge (golf), wedge primarily designed for getting out of bunker (golf), sand bunkers. It has the widest Glossary of golf#Sole, sole of any wedge, which provides the greatest amount of bounce (golf), bounce, allowing the club head to glide through sand and avoid digging in. After Gene Sarazen had success in 1932 with a new club that he had invented for sand play, its popularity quickly grew. The club can be advantageous in other soft lies—such as thick Rough (golf), rough, soggy ground, or mud—and is also used from firmer grass lies for Glossary of golf#Lob, lobs or Chip (golf), chips. History Clubs with the loft of the sand wedge can be traced as far back as Young Tom Morris, who used a "rut iron" for play from troublesome lies. Such irons were, however, traditional in construction, without the wider, heavier sole featured on the modern sand wedge. Gene Sarazen began to win tournaments in 1932 with a new cl ...

Investment Casting
Investment casting is an industrial process based on lost-wax casting, one of the oldest known metal-forming techniques. The term "lost-wax casting" can also refer to modern investment casting processes. Investment casting has been used in various forms for the last 5,000 years. In its earliest forms, beeswax was used to form patterns necessary for the casting process. Today, more advanced waxes, refractory materials and specialist alloys are typically used for making patterns. Investment casting is valued for its ability to produce components with accuracy, repeatability, versatility and integrity in a variety of metals and high-performance alloys. The fragile wax patterns must withstand forces encountered during the mould making. Much of the wax used in investment casting can be reclaimed and reused. Lost-foam casting is a modern form of investment casting that eliminates certain steps in the process. Investment casting is so named because the process invests (surrounds) t ...

Metal Clubs
A metal () is a material that, when polished or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. These properties are all associated with having electrons available at the Fermi level, as against nonmetallic materials which do not. Metals are typically ductile (can be drawn into a wire) and malleable (can be shaped via hammering or pressing). A metal may be a chemical element such as iron; an alloy such as stainless steel; or a molecular compound such as polymeric sulfur nitride. The general science of metals is called metallurgy, a subtopic of materials science; aspects of the electronic and thermal properties are also within the scope of condensed matter physics and solid-state chemistry, it is a multidisciplinary topic. In colloquial use materials such as steel alloys are referred to as metals, while others such as polymers, wood or ceramics are nonmetallic materials. A metal conducts electricity at a temperature of absolute zero ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitching Wedge
Pitch may refer to: Acoustic frequency * Pitch (music), the perceived frequency of sound including "definite pitch" and "indefinite pitch" ** Absolute pitch or "perfect pitch" ** Pitch class, a set of all pitches that are a whole number of octaves apart ** Relative pitch, the ability to identify a given musical interval between two notes * Pitch accent, a form of accentuation in speech Business * Sales pitch, a line of talk that attempts to persuade someone or something ** Pitch (filmmaking), a proposal for a film ** Elevator pitch, a very short sales presentation, allegedly short enough to be made during an elevator ride Measurement Movement about the transverse axis * Pitch angle (or pitch rotation), one of the angular degrees of freedom of any stiff body (for example a vehicle), describing rotation about the side-to-side axis ** Pitch (aviation), one of the aircraft principal axes of rotation (nose-up or nose-down angle measured from horizontal axis) ** Pitch (ship ...

Gap Wedge
In golf, a gap wedge, also known as an approach wedge, is a wedge A wedge is a triangle, triangular shaped tool, a portable inclined plane, and one of the six simple machines. It can be used to separate two objects or portions of an object, lift up an object, or hold an object in place. It functions by conver ... used to hit a shot with higher and shorter trajectory than a pitching wedge and lower and longer trajectory than a sand wedge. The name derives from the club's design to fill the "gap" between sand and pitching wedges. History Over time the loft angle on irons in matched sets has been reduced for multiple reasons. Manufacturers, always wanting to advertise longer distances than their competitors, sometimes "cheat" by de-lofting their iron sets by a degree or two compared to their competitor's set, producing between 2-5 yards of extra distance per degree of "strengthening". In addition, several significant advances in clubhead design, most notably the 1970s developm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golf Club, Ping G10 24º Hybrid
Golf is a club-and-ball sport in which players use various clubs to hit a ball into a series of holes on a course in as few strokes as possible. Golf, unlike most ball games, cannot and does not use a standardized playing area, and coping with the varied terrains encountered on different courses is a key part of the game. Courses typically have either 9 or 18 ''holes'', regions of terrain that each contain a ''cup'', the hole that receives the ball. Each hole on a course has a teeing ground for the hole's first stroke, and a putting green containing the cup. There are several standard forms of terrain between the tee and the green, such as the fairway, rough (tall grass), and various ''hazards'' that may be water, rocks, or sand-filled ''bunkers''. Each hole on a course is unique in its specific layout. Many golf courses are designed to resemble their native landscape, such as along a sea coast (where the course is called a ''links''), within a forest, among rolling hills, ...

Lob Wedge
A lob wedge, also known as a lofted wedge or an L-Wedge, is a wedge used in the sport of golf, known for being one of the shortest-hitting clubs and providing the most loft on a shot. Lob wedges are used to produce shots with a very high arc, and are most often used for shots over hazards and other obstructions. Due to the high arc of the shot the lob wedge, like the other wedges in the set of irons, produces little roll after landing on the putting green and can even be used to produce backspin if necessary. Lob wedges are one of the newest additions to the modern collection of golf clubs and, along with the sand wedge and gap wedge, were not included prior to 1931. Design Lob wedges are part of the iron family of golf clubs and are designed for short, high arc shots. Lob wedges and ultra lob wedges are designed with the shortest shafts and the highest loft of all golf clubs. Regular lob wedges may come in a variety of lofts, usually starting around 56 degrees and approaching 6 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
