I can't say for sure why the people who chose to put your question on hold made that choice, but I suspect that the question is long enough that the specific conceptual question you want to ask isn't clear. As of the current revision 19, I'm assuming this is the specific conceptual question:
[...] However, would that not cause the force due to pulling to get cancelled out?
That's a perfectly fine thing to ask. I think removing the extra free-body diagrams as you did in the latest edit will help make it more clear, but you could even go a little further and make the summary of the work you did more concise. Remember that the focus of the post should be the specific conceptual question you want to ask (again, presumably what I quoted above), and most of your post should be devoted to setting up that question. Anything else you can just briefly summarize.
I wouldn't mind voting to reopen the question in its current state (revision 19), but I'd like to hear from at least one (preferably several) of the close voters first to see whether there were other issues that caused them to vote as they did.
