9 Iron
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 a ... [...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. Wood (golf), Woods are mainly used for long-distance fairway or tee shots; iron (golf), irons, the most versatile class, are used for a variety of shots; Hybrid (golf), hybrids that combine design elements of woods and irons are becoming increasingly popular; putter (golf), 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 r ...

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 1899 U.S. Open (golf), U.S. Open. At the time of its final edition in 2006 PGA Tour, 2006, it was the third-oldest active PGA Tour tournament, after The Open Championship, The Open (1860 Open Championship, 1860) and U.S. Open (golf), U.S. Open (1895 U.S. Open (golf), 1895). The tournament was held a total of 103 times over the course of 108 years. The event was not held in 1900, 1918 (World War I), and 1943–45 (World War II). Players from the U.S. won the tournament 77 times, followed by Scotland with fifteen wins. Walter Hagen had the most victo ...

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 sta ... [...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. Splint, Sarah Field. The Art of Cooking and Serving. Cincinnati, Ohio: The Procter & Gamble Co., 1930. "Table Service in the Servantless House" pp. 3-4, "The House with a Servant" p. 27 Individual butter knives have a round point, so as not ...

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 Teeing ground, tee (earning him the nickname "Long John"), his non-Country club, country-club appearance and attitude, his exceptionally long backswing, the inconsistency of his play (with exceptional performances and 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 (Eswatini), 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 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Torque
In physics and mechanics, torque is the rotational analogue of linear force. It is also referred to as the moment of force (also abbreviated to moment). 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 . Just as a linear force is a push or a pull applied to a body, a torque can be thought of as a twist applied to an object with respect to a chosen point; for example, driving a screw uses torque to force it into an object, which is applied by the screwdriver rotating around its axis to the drives on the head. Historical terminology The term ''torque'' (from Latin , 'to twist') is said to have been suggested by James Thomson and appeared in print in April, 1884. Usage is attested the same year by Silvanus P. Thompson in the first edition of ''Dynamo-Electric Machinery''. Thompson describes his usage of the term as follows: Today, torque is referred to using d ... [...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 ...

Lofted Trajectory
In physics, projectile motion describes the motion of an object that is launched into the air and moves under the influence of gravity alone, with air resistance neglected. In this idealized model, the object follows a parabolic path determined by its initial velocity and the constant acceleration due to gravity. The motion can be decomposed into horizontal and vertical components: the horizontal motion occurs at a constant velocity, while the vertical motion experiences uniform acceleration. This framework, which lies at the heart of classical mechanics, is fundamental to a wide range of applications—from engineering and ballistics to sports science and natural phenomena. Galileo Galilei showed that the trajectory of a given projectile is parabolic, but the path may also be straight in the special case when the object is thrown directly upward or downward. The study of such motions is called ballistics, and such a trajectory is described as ballistic. The only force of m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Center Of Gravity
In physics, the center of mass of a distribution of mass in space (sometimes referred to as the barycenter or balance point) is the unique point at any given time where the weighted relative position of the distributed mass sums to zero. For a rigid body containing its center of mass, 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 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
