Week two of Tom’s training is similar to week 1, but instead of being down on the production floor, he is spending a week in our test lab. Our lab measures all aspects of clubs from loft, lie, and weight to thickness, durability, and even the sound each club makes. They are also constantly running player and robot tests comparing our clubs to the competition. We want Tom to be an expert on all of this equipment. I still haven’t really worked with Tom, so I don’t have much to say. Here are his comments:
Hi all, I’m progressively getting closer to my desk and the job that I was actually hired for. This week, I am at least in the R&D department and occasionally see the others in my research group, but as was mentioned I am working in the test lab. The lab does all of the experimental testing that is required of CG clubs and competitors’ equipment. I was exposed to everything that is done, but I was asked to focus on golf club shafts. It seemed that everyone had been planning this because there were about 60 shafts – that needed to be catalogued and tested – waiting for my arrival. I can do all told about 15-18 in a day if it is all that I do (I’ve gotten pretty efficient). I finished about 35 and left the rest for someone else…sorry to everyone in the lab.
Part of my training as a new hire is to analyze the set of clubs that I currently play with in order to determine from an engineering stand point why these clubs are incorrect for my game. This required me to hit every club in my bag in front of our TrackMan. This took an entire day out at the range and was very exhausting. Someone, who shall remain nameless, told me that I had to hit 10-15 good shots per club in front of the equipment in order to have enough data. So, a little non-brainteaser math, 10-15 good shots times 12 clubs equals…well it was a lot and my arms are still sore two days later, but I did get to spend my entire work day hitting golf balls at the driving range so no complaints.
In the past week, I was shown how to test everything that can possibly measured on a golf club. From simple quantities such as weight and length to more advanced experiments such as sound testing and EI/GJ analysis (shaft stiffness and torque profiles). It was a good weak, and I actually felt like an engineer. Getting closer!
In terms of last week’s logic problem, I got some really good responses. Thanks to all who posted an answer. Congratulations to C. Evans for being the first person to get the correct answer. See last week’s blog to read all the creative responses. http://blog.clevelandgolf.com/?p=566. Many people said to weigh one coin from each machine, then remove one coin at a time, but that takes multiple measurements, and you were only allowed one weight measurement. As many of you answered correctly: you have to weigh a different number of coins from each machine, then see how light the total is compared to what it should be (ex. If the total weight is 5 grams less than what it would be if they were all were 10 gram coins, then the machine that you weighed 5 coins from is defective).
I wanted to add that my personal favorite solution to the brainteaser was to put the coins in a vending machine to see which coin was returned. Kudos…creative and humorous.
Below is this week’s problem. Like John said last week, the first person with the correct answer wins a Cleveland Golf Tour hat, and everyone who attempts gets entered to win a specialized “First Run” CG15 wedge (one of the first 250 CG15’s ever made).
(From John – If you comment twice to the same post, you will only get one entry, but if you comment to every blog you can get up to 5 total entries. Try to make the comments interesting though…)
Attic Light: You have 3 light switches in your basement and one of them controls a light in your attic (the other two do nothing). You have to figure out which of the 3 switches controls the attic light, but you are only allowed one trip up to your attic. You can’t see the attic from your basement, and you’re not allowed to use any equipment or people to help you (no multimeters, video cameras, etc). What do you do?
