Golf & Its Equipments

Controlling Swing Speed with Driver Loft in Golf

Over the years, I realized that some golfers simply don’t have the proper equipment to play golf and this could kill your decision to continue or to stop this beautiful sport. All I hear on a golf club is remarks about their swing, but never on equipment. They think that any sets, the cheapest, could fit to play this game, because they don’t play enough during the season. I never said and will never say that, buying more expensive clubs, will make you play better. However if you have the proper equipment for your swing, specially amateur golfers, not only will you enjoy this sport, you will become addicted, as this is the best drug I ever took on my life.

With the advance technology of the golf balls with lower spin rates, manufactures found something new with drivers. During the 80s and 90s people thought that lower the loft, farther the ball would go. What the golf research has found is that in order to obtain distance, the club head should launch the ball at higher angles than in the past. This means that many of us are probably playing drivers with too little loft. Driver loft should match your swing speed. The slower your swing speed, the more lot you should have. If your normal swing speed is between 80 and 90 (the average for most male golfers) you should be using a driver with about 12 degrees of loft. Combined with the new balls this means your launch angle and spin rate will be optimized.

Like I always said in the past, when shopping for a driver in a golf store, if the salesman tells you, that, with that special driver, you will hit 250 yards, knowing your swing speed at 80, just change the salesman or even the store as they are only there to make money with you.

Of course this is just a base recommendation. Reason is, if your swing speed is 100 miles per hour, and because of your golf swing, you are hitting very low, there is always an option to change to a higher loft; however your shaft could be also a problem if you have a very low torque. The best recommendation would be to see a professional custom builder, who has the equipment to verify your swing speed, shafts, golf balls that you are using, the length, etc. He will be able to make recommendations to obtain the normal distance, according to your speed. Remember, he will not make a Tiger Wood with you!

Shaving Strokes Off Your Golf Game

If you are a golfer who wants some advice that you can actually use. There are certain things that you can do to shave a couple of strokes from your golf game.

The first piece advice that anyone can give you is to try to develop a good sense of rhythm in accordance to your swing and golf game. There are plenty of golfers who get themselves into a bad rhythm which influences bad habits, simply because they rush themselves through the course. The truth is by taking your time and developing a steady swing it can save you on those poorly hit shots thus saving you a stroke or two.

The second piece of advice to shave some strokes off your golf game is to change your putter to one that is more suitable to your tempo and swing. A lot of times golfers tend to use a putter that is either to light or to heavy for them. This can lead to either over hitting or under hitting the golf ball on the putting green, not to mention what it does to your line of the put. That is why many more golfers are now buying a belly putter, it’s a putter with an extended shaft that pokes the golfer’s belly, there able to regulate their putting stroke better since the weight has become more balanced.

The third piece of advice you can use to shave those strokes off your game is to make sure and use the proper tees. A lot of beginners seem to get better results when they tee up the ball high, the added height helps them hit the ball cleanly thus reducing them from scuffing the ground.

The fourth piece of advice that can be given to a golfer in search of shaving a stroke or two from their game is to scout the golf course before your golf game. Even if you just look at the golf course map, this way you can identify the hardest holes and try to come up with a strategy that can help you stay out of the hazard and in play thus reducing your score.

The last piece of advice that can be considered in shaving some strokes off your game is to relax when you are out there, enjoy the game and the golf course when you are out there. Many golfers tend to play with a competitive mind set making them play poorly. Tons of golfers will tell you that having a clear head and positive thinking can help you more with your golf game than any other piece of advice out there.

Why golf ball has dimples ?

The answer to this question can be found by looking at the aerodynamic drag on a sphere. There are two types of drag experienced by a sphere. The first is the obvious drag due to friction. This only accounts for a small part of the drag experienced by a ball. The majority of the drag comes from the separation of the flow behind the ball and is known as pressure drag due to separation. For laminar flow past a sphere, the flow separates very early as shown in Figure 1. However, for a turbulent flow, separation is delayed as can be seen in Figure 2. Notice the difference in the size of the separation region behind the spheres. The separation region in the turbulent case is much smaller than in the laminar case. The larger separation region of the laminar case implies a larger pressure drag on the sphere. This is why the professor experienced a longer drive with the marked ball. The surface roughness caused the flow to transition from laminar to turbulent. The Book results for enterprise risk shows turbulent flow has more energy than the laminar flow and thus, the flow stays attached longer.


Laminar flow fig 1



Turbulent Flow fig 2

So, why dimples? Why not use another method to achieve the same affect? The critical Reynolds number, Recr, holds the answer to this question. As you recall, Recr is the Reynolds number at which the flow transitions from a laminar to a turbulent state. For a smooth sphere, Recr is much larger than the average Reynolds number experienced by a golf ball. For a sand roughened golf ball, the reduction in drag at Recr is greater than that of the dimpled golf ball. However, as the Reyn olds number continues to increase, the drag increases. The dimpled ball, on the other hand, has a lower Recr, and the drag is fairly constant for Reynolds numbers greater than Recr.

Therefore, the dimples cause Recr to decrease which implies that the flow becomes turbulent at a lower velocity than on a smooth sphere. This in turn causes the flow to remain attached longer on a dimpled golf ball which implies a reduction in drag. As the speed of the dimpled golf ball is increased, the drag doesn’t change much. This is a good property in a sport like golf.

Although round dimples were accepted as the standard, a variety of other shapes were experimented with as well. Among these were squares, rectangles, and hexagons. The hexagons actually result in a lower drag than the round dimples. Perhaps in the future we will see golf balls with hexagonal dimples

Origin of the Game: Golf

A golf-like game is recorded as taking place on 26 February 1297, in the Netherlands, in a city called Loenen aan de Vecht. Here the Dutch played a game with a stick and leather ball. Whoever hit the ball into a target several hundreds of meters away the most number of times, won. However, golf is generally considered to be a Scottish invention, as the game was mentioned in two 15th-century Acts of the Scottish Parliament, prohibiting the playing of the game of gowf. Scholars, however, suggest that this refers to another game which is much akin to shinty or hurling, or to modern field hockey rather than golf. They point out that a game of putting a small ball in a hole in the ground using golf clubs was played in 17th-century Netherlands rather than Scotland. The word golf is an alteration of Dutch “kolf” meaning “stick, “club” and “bat” . There are reports of even earlier accounts of golf from continental Europe.
