The Automatic Golf Club

03/18/2009 11:48 PM

A follow up regarding, the questions ask about an automatic golf club, that were valid questions dealing with real engineering issues, but received mostly "wise crack answers" which is fine, but lets hear from the real engineers on the subject. I thought, what if I tried to take that on as a project what would it take. The list of questions that came to mind begin to get rather long.

I will list a few to get the discussion juices flowing....

To drive a golf ball 250 yards what PSI would be required?

What would be the means to develop the PSI?

What would the SI be?

Since every golf shot is a different distance how do you vary the distance?

What is the mass weight required for the moving part that strikes the ball?

What is the travel distance required by the striking component part?

What speed would be required for the striking component part?

How much does the ball compression add to the ball travel distance?

What type of material is required for the component parts?

If this automatic club was used at a golf resort by a golfers wife or a girl friend, his wife did not know about, could she use it the same way, she would a conventional driver club, with the exception being the automatic club would hit the ball without swinging the club, she would only have to position the club behind the ball pointed in the desired direction of travel.

She just came from South Beach, she is attractive and dressed barely legal to be on a golf course, is she able to play golf with an experienced golfer without slowing his game, even though she has never played before in her life?

These are a few of the questions, to get started, get ready this is not going away soon.

I promise I will not ask what happens if I turn the lights on at a given speed. I said this in order to pacify the wise guys, do not get me wrong, we also need wise guys to keep things in perspective.

1) For all single line questions the answer is to study the projectile motion (this is if I am not wrong class 10 dynamics)

After the ball falls on ground though all the equations will change and from there on it will be in-elastic collission at an angle (and hence will depend on the coeff of elasticity of both)

In the end it rolls and then it will be the coeff of friction.

2) For the larger question- this is a higher level one (officially beyond school level, though a lot of school children have studied this subject) - If even though she has never played before in her life , the experienced man has to necessarily be gentle slow for a couple of holes after that he can speed up, in-fact he may speed up perforce.

BTW I forgot to add in the second question the order of motione are slightly mixed up ie

1: motion type 2

2: motion type 3

3: motion type 1

Hello,

There is a video on Utube of an automatic golf club. I saw it a year or so ago. It is probably still available. What I remember of it is that the player addressed the ball and pressed a trigger which operated a sliding face in the head of the club. This hit the ball as the player held the club steady behind the ball. Loft of the ball was achieved by the attack angle of the club and overall was a 'blast' to watch.

Question is, is it really golf as we know and LOVE/HATE it, or a 'hybrid' of golf to become skilled at that you really need.

Your fundamental question begs to be answered in a manner used by any good Irishman, by asking you a question.

Why have an automatic golf club if you have to swing the club yourself. What part of automatic golf club is automatic, the power? the swing speed?. the swing plane? the loft of the face at impact? the adjustment for local conditions?, the adjustment for size of ball, distance, wind, rain, sun, fog, haze and I hope you get the picture.

Forget golf and have some fun shooting "spuds", at your local 19th hole, using a home made potato gun. See how the patrons like it and whether they will come next week with their own guns!

Good Luck

AMAZING!! I was just thinking about a spud gun resized to shoot golf balls. How might one putt with a spud gun?

Taking this concept to it's ultimate extreme, if a club was able to provide the proper force & direction, guided by GPS + optical, such that a hole in one occurred on all 18 holes - no one would "play"!

Hi Roy,

I admire your inquisitive mind. however, there are some limits to where ingenuity stops, and among those limits are in sports.

as expressed by the players of the sport itself, those "wise crack answers" have some basis. to satisfy your curiosity, I'd invite you to visit the Untied States Golf Association website, and check out the rules of the game, specifcally the section about the form and make of clubs (sect. 4.1).

your idea, while it is indeed creative, just won't be acceptable in the game & will be considered *cheating*.

HTH!

I goofed on that post above. Of a truth, the error was pure typo. the word should read "United"! Sorry...

I already hit the balll 250+ yards. (My longest is 312)

And the PSI (Personal Swing Inclination) I use is 1 pint per 2 holes. By the time I get to 18 I don't care what my score is.

A fellow came in from his Saturday golfing, threw his clubs in the corner and plopped down in his chair. His wife came in and said "Hi honey! How did your golf game go?"

"Horrible!!" he replied... "On the third green, my partner George had a heart attack."

"That is horrible!" she responded...

"You bet. After that, it was Hit the ball and drag George... Hit the ball and drag George... Hit the ball and drag George...

Hi Roy H,

HS!! How did I miss the previous discussion on automatic clubs? Must have slept through that one.

Without going into deep details, to make a golf ball travel 250 yards (all carry, no bounce/roll), you must strike the ball with a clubhead speed of approximately 95 - 100 mph at impact with a starting trajectory of about 12 degrees and a backspin rate of about 1800+ rpm. Optimum trajectory is of course 45 degrees but the backspin will increase the initial 12 degree trajectory as it travels down range.

The perfect trajectory would have its apex at the exact midway point between golfer and final destination of the ball. This, however is almost impossible to achieve but can be enhanced with the proper fitting of the club parameters to the golfer.

As to whether an automatic club would be advantageous in helping a rank amateur keep up with a mid to low handicap player, well, the club would have to have adjustable loft angles and speed changeability AND it would have to be able to teach you how to chip and putt.

All said, the club would only be usable for amateur daily play as the rules of golf would not allow it in any other venue.

Very good answers, to what seemed to be reasonable questions, that were originally ask.
