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 irons are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golf Clubs
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 ...

Western Open
The Western Open was a professional golf tournament in the United States, for most of its history an event on the PGA Tour. The tournament's founding in 1899 actually pre-dated the start of the Tour, which is generally dated from 1916, the year the PGA of America was founded. The Western Open, organized by the Western Golf Association, was first played in September 1899 at the Glen View Club in Golf, Illinois the week preceding the U.S. Open. At the time of its final edition in 2006, it was the third-oldest active PGA Tour tournament, after The Open ( 1860) and U.S. Open ( 1895). The tournament was held a total of 103 times over the course of 108 years. The event was not held in 1900, nor in 1918 because of World War I, and not from 1943-1945 because of World War II. Golfers from the United States won the tournament 77 times, and players from Scotland won it 15 times. Walter Hagen had the most victories with five wins, and 17 other players won the event at least twice. Two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lee Trevino
Lee Buck Trevino (born December 1, 1939) is an American retired professional golfer who is regarded as one of the greatest players in golf history. He was inducted to the World Golf Hall of Fame in 1981. Trevino won six major championships and 29 PGA Tour events over the course of his career. He is one of only four players to twice win the U.S. Open, The Open Championship and the PGA Championship. The Masters Tournament was the only major that eluded him. He is an icon for Mexican Americans, and is often referred to as "The Merry Mex" and "Supermex," both affectionate nicknames given to him by other golfers. Early life Trevino was born in Garland, Texas, into a family of Mexican ancestry. He was raised by his mother, Juanita Trevino, and his grandfather, Joe Trevino, a gravedigger. Trevino never knew his father, Joseph Trevino, who left when his son was small. During his childhood, Trevino occasionally attended school and worked to earn money for the family. At age 5, he start ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butter Knife
In common usage, a butter knife may refer to any non-serrated table knife designed with a dull edge and rounded point; formal cutlery patterns make a distinction between such a place knife (or table knife) and a butter knife. In this usage, a butter knife (or ''master butter knife'') is a sharp-pointed, dull-edged knife, often with a sabre shape, used only to serve out pats of butter from a central butter dish to individual diners' plates. Master butter knives are not used to spread the butter onto bread: this would contaminate the butter remaining in the butter dish when the next pat of butter was served. Rather, diners at the breakfast, the luncheon, and the informal dinner table use an individual butter knife to apply butter to their bread.Sarah Field Splint, Splint, Sarah Field.

John Daly (golfer)
John Patrick Daly (born April 28, 1966) is an American professional golfer on the PGA Tour and PGA Tour Champions. Daly is known primarily for his driving distance off the tee (earning him the nickname "Long John"), his non- country-club appearance and attitude, his exceptionally long backswing, the inconsistency of his play (with some exceptional performances and some controversial incidents), and his personal life. His two greatest on-course accomplishments are his "zero-to-hero" victory in the 1991 PGA Championship, and his playoff victory over Costantino Rocca in the 1995 Open Championship. In addition to his wins on U.S. soil, Daly has won accredited pro events in South Africa, Swaziland, Scotland, Germany, South Korea, Turkey, and Canada. According to official performance statistics kept since 1980, Daly in 1997 became the first PGA Tour player to average more than 300 yards per drive over a full season. He did so again in every year from 1999 to 2008, and he was the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rules Of Golf
The rules of golf consist of a standard set of regulations and procedures by which the sport of golf should be played. They are jointly written and administered by The R&A (spun off from The Royal and Ancient Golf Club of St Andrews in 2004) and the United States Golf Association (USGA). The R&A is the governing body of golf worldwide except in the United States and Mexico, which are the responsibility of the USGA. The rule book, entitled ''Rules of Golf'', is updated and published on a regular basis and also includes rules governing amateur status. The rules of golf cover all aspects of play, including definitions of terminology, procedures and equipment parameters. It also prescribes specific penalties that may be enacted in certain situations and for rule infractions. A central principle, although not one of the numbered rules, is found in the R&A rule book's inside front cover: "Play the ball as it lies, play the course as you find it, and if you cannot do either, do what is fai ...

Torque
In physics and mechanics, torque is the rotational equivalent of linear force. It is also referred to as the moment of force (also abbreviated to moment). It represents the capability of a force to produce change in the rotational motion of the body. The concept originated with the studies by Archimedes of the usage of levers, which is reflected in his famous quote: "''Give me a lever and a place to stand and I will move the Earth''". Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object around a specific axis. Torque is defined as the product of the magnitude of the perpendicular component of the force and the distance of the line of action of a force from the point around which it is being determined. The law of conservation of energy can also be used to understand torque. The symbol for torque is typically \boldsymbol\tau, the lowercase Greek letter ''tau''. When being referred to as moment of force, it is commonly denoted by . In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Fiber
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers (Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester, or nylon, are sometimes used. The properties of the final CFRP product can be affected by the type of additives introduced to the binding matrix (resin). The most common additive is silica, but other addi ...

Lofted Trajectory
Projectile motion is a form of motion experienced by an object or particle (a projectile) that is projected in a gravitational field, such as from Earth's surface, and moves along a curved path under the action of gravity only. In the particular case of projectile motion of Earth, most calculations assume the effects of air resistance are passive and negligible. The curved path of objects in projectile motion was shown by Galileo to be a parabola, but may also be a straight line in the special case when it is thrown directly upwards. The study of such motions is called ballistics, and such a trajectory is a ballistic trajectory. The only force of mathematical significance that is actively exerted on the object is gravity, which acts downward, thus imparting to the object a downward acceleration towards the Earth’s center of mass. Because of the object's inertia, no external force is needed to maintain the horizontal velocity component of the object's motion. Taking other fo ...

Center Of Gravity
In physics, the center of mass of a distribution of mass in space (sometimes referred to as the balance point) is the unique point where the weight function, weighted relative position (vector), position of the distributed mass sums to zero. This is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where the entire mass of an object may be assumed to be concentrated to visualise its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton's laws of motion. In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the case for wikt:hollow, hollow or open-shaped object ...
