It says nowhere that this site is restricted to only theoretical or conceptual Physics questions only, and everything related to physics problem solving is banned.
Tell me if I'm wrong about this and point me to the reference, or make a new thread to discuss it to change the scope officially.
Let me quote Mew's comment below this answer from another related question:
I don't believe that providing complete solutions is detrimental to
students, and in fact I believe the best way for students to learn the
basics of physics is to look at as many complete solutions as
possible. I believe this method is far superior than asking the
student to attempt to solve the problem by themselves. When a student
has seen many problems, I believe they will have no trouble in
developing an intuition to solve far more physics problems, and will
have much more refined thought process than the students who went off
on tangents trying to solve problems using unconventional methods – Mew
I agree with him.
When I was a student I always got A+ for all may physics exams in high school, because they always included problems of types the teacher already showed us how to solve (not the same problems, but with different numbers and conditions).
Due to my performance I always went to Physics competitions but I weren't too successful in them initially. The reasons: the problems they gave me to solve was of types I never seen before.
Let me show you an example. Electric circuits. Most students learn how to calculate the resistance, inductance and capacitance when these elements connected in series or parallel. But what do you do when you are faced with an arbitrary graph of capacitors, resistances or coils which you cannot rearrange into the usual series parallel structure? I was flinched by these tasks, I didn't even know how to start at all!
Eventually after sending and receiving lots of letters (I didn't even had internet that time), discussing with peers other competitors and teachers, I managed to learn helluva lots of tricks and tips and approaches you can't find in any text book, which eventually got me to the final rounds and took the 4th prize.
I don't have 10k+ reputation so I can't open the linked question in the example. But I think catch-all questions self answered or not, that ask
"What approach should I use when solving problems of this class" (without actual numbers plugged in) would be very useful for students who are preparing for competitions or exams, engineers writing simulation software looking for the methods, etc.
Then again if this site isn't for helping students learn the methods and know/how of problem solving than we should point that out in the tour and the help/ontopic as well.
