I was the author of the subject question. There was no intention to 'hack' the system, but I did make the mistake of posting answers to point out the multiple errors in some of the "terrible" answers instead of using the comments section. For that I apologise. I felt compelled to respond, because I assumed knowledgeable high rep users would either downvote the terrible answers or post quality answers with the correct solutions and point out errors, but they did not.
I also posted an edit complaining about the amount of serial down voting, because some people were were so outraged to the challenge of their ingrained worldview, they not only downvoted my posts in that thread, but when on a campaign of looking for my historical posts in other threads and downvoting them as well and I am glad that the algorithm corrected that.
Later on, rob deleted some of my self answers and comments in the question and to be honest I was glad he did, because the whole thing had got messy and I apologise for being partly responsible.
A good question, in the Stack Exchange model, is one that has
definitive answers.
I feel my question does have a definitive answer which is "Given a mechanism to stop the chain coming off the gears due to centrifugal force and given a long enough chain so the major part of the chain drive is straight, the chain drive will contract and the spring on the left will be stretched."
However, judging by the yo-yo voting on the question about 50% of members think the chain will contract and the other half thing it will not. Clearly if a measurement was made there would be a definitive answer and after over 100 years of relativity we should be able to calculate what would be measured. The answer is not an opinion, its a fact. What would be measured?
As far as I am concerned the question is a good question, It has garnered more than a 1000 views and the voting reveals that about half the responders have the opposite view to the other half and so a large number of the members are suffering from a misconception which needs clearing up. I feel high rep users could help by either posting authoritative answers or at the very least, downvoting the 'terrible' answers or upvoting the good answers which takes less than a minute. Isn't that how this forum is supposed to work?
Any way, I think rob did the right thing and the question is much better for his edits and I apologise for the inconvenience caused due to getting too emotionally involved.
