What Are Golf Balls Made Of That Make Them Go So Far?
In the chemistry of air pressure, turbulence, and aerodynamics, surface structures are vital physical element. History has it that there are things that seem to be peculiar on their make-up hundreds of years ago which eventually came up with a better composition based on scientific research. And a golf ball is the best paradigm of this theoretical stand in history.
During the earliest days of golf on the eastern coast of Scotland, most players used ancient apparatus in order to play the game in a more disorganized and informal way. Here, the first clubs and golf balls are made up of wood.
It was on 1618 that the feather golf ball was finally introduced. This was commonly known as the "Featherie". This feather golf ball was a handcrafted ball made with goose feathers securely pressed into a horse or cowhide sphere. This is being done while the ball is still wet. After drying, the leather shrank and the feathers expanded creating a hardened ball.
But because these kinds of golf balls are specially handcrafted, they usually cost higher than the clubs. In doing so, only a few privileged people could afford to play golf during those times.
Next, came the Guttie golf ball. This prehistoric kind of golf ball was made from the rubber like sap of the Gutta tree that can be found in the tropics. Normally, these Guttie balls can be easily shaped into a sphere when hot and eventually used as a golf ball. With its rubber nature, guttie balls can be cheaply reproduced and can be easily repaired by reheating and reshaping.
However, between the two earliest forms of golf balls, the feather golf ball was said to travel farther than the gutties. This is due to the smooth surface of the gutties that limits the capacity of the golf ball to cover more distance.
With this new scientific analysis, the developers of golf ball finally came up with balls with the "dimples" that are predominant in modern golf balls nowadays.
Dimples are crafted into golf balls so as to reduce the aerodynamic drag, which will be acting on the ball if it were totally smooth. This is because smooth balls, when sailing through the air, leave a huge pocket of low-pressure air in its stir therefore creating a drag. With the application of drag, the ball slows down.
Hence, by having dimples on golf balls, the pressure differential goes down and the drag force is reduced. These dimples create turbulence in the air surrounding the golf ball. This, in turn, forces the air to clasp the golf ball more closely. By doing so, the air trails the warp created by the ball towards the back instead of flowing past it. This results to a smaller wake and lesser drag.
Dimples also help players to put backspin on a shot making the golf ball break off on the putting green.
The idea of putting dimples on golf balls can be traced back during the gutta percha phase. Coburn Haskell introduced the one-piece rubber cored ball encased in a gutta percha sphere. It was during this time when the players observed how their shots become more and more predictable as their balls turned rough from play.
When William Taylor applied the dimple pattern to a Haskell ball in 1905, golf balls finally took their modern form.
From then on, dimpled golf balls were officially used in every golf tournament. In 1921, the golf balls took its form with standard size and weight.
Today, there is an abundant selection of golf balls to fit different golf game and condition. There are golf balls that offer control, while some offer distance. In whatever ways golf balls vary, only one thing is common and known. Golf balls are not just elements of the sports arena; they are more than ever paradigm of a concept in physics.
A History of the Golf Balls
In the earliest days of golf on the eastern coast of Scotland, players used primitive equipment to play the game in a rather haphazard and casual manner. The first clubs and balls specifically made for golf were fashioned from wood. One documented reference is that of a John Daly playing with a wooden ball in 1550.
In 1618 the feather golf ball or 'Featherie' was introduced. This was a handcrafted ball made with goose feathers tightly packed into a horse or cow hide sphere. The feathers and leather were fashioned into a ball while wet. As the assembly dried out the leather shrank and the feathers expanded to create a hardened ball. The ball was then finished off by painting it and punched with the ball-makers mark. Quality varied according to the skill of the craftsman. Unfortunately, the handcrafted nature of the balls meant that they were priced beyond the pockets of the masses, sometimes more expensive than a club. Notable ball-makers of the 1600s were Andrew Dickson, Leith and Henry Mills, St Andrews.
The introduction of the Gutta Percha ball or 'Guttie' in 1848 by Rev Adam Paterson of St. Andrews and the spread of the railways directly contributed to the expansion of golf. The Guttie ball was made from the rubber like sap of the Gutta tree found in the tropics. When heated the rubber could easily be fashioned into a sphere and used as a golf ball. Not only could the ball be relatively cheaply produced, it could also be easily repaired by re-heating and then re-shaping. Initially Gutties had a smooth surface which meant that they didn't travel as far as the Featheries. The balls were usually stamped with the ball makers stamp, most notably Allan Robertson.
After 1880, gutties were produced with patterns on their surface in an attempt to reproduce the distance characteristics of a scored Featherie. With the Victorians came industrialisation and mechanisation, and by 1890 Gutties were being made in moulds which further increased their affordability, consistency and quality. The most notable pattern of the period was the 'Bramble' - raised spherical bumps across the surface of the ball. Many of the rubber companies including Dunlop began mass-producing balls which killed off the handcrafted ball business.
In 1898, Coburn Haskell introduced the one-piece rubber cored ball which was universally adopted by 1901 after it proved so effective in the British and US Opens. These balls looked just like Gutties but gave the average golfer an extra 20 yards from the tee. These balls were constructed from a solid rubber core wrapped in rubber thread encased in a gutta percha sphere. Once W. Millison developed a thread winding machine, Haskell balls were mass-produced and therefore more affordable.
Throughout this period there was a lot of experimentation with the patterns on golf balls - one of the reasons why golf collecting is so interesting. When William Taylor first applied the dimple pattern to a Haskell ball in 1905, golf balls took on their modern form. The dimple pattern maximises lift while minimising drag.
Manufacturers continued to experiment with golf ball design including Goodrich who introduced the pneumatic ball in 1906 (the patent was held by T. Saunders and filed in 1901). Quite simply this was a Haskell ball with a compressed air core which unfortunately was prone to expansion with heat and therefore causing the ball to explode. Others tried mercury, cork and metal cores. Only in 1972, when Spalding introduced the first two piece ball, the Executive, was the basic Haskell design improved upon.
In 1921, the R&A and USGA standardised the size and weight of the ball. Since then further constraints have been proposed which are detailed in the rules. Between 1931 and 1990, both organisations differed on the dimensions of the golf ball which meant that the game played on either side of the Atlantic was similar but different.
Today there is a rich variety of golf balls to suit the individual game and circumstance. Some offer control, some offer distance while others are suitable for practice only. Antique golf balls are avidly collected and are becoming increasingly valuable. A dimple patterned Guttie in good condition is worth about $US 500.
