I certainly respect Big Piston's formal instructing experience, which is vastly more than my none! I will tread very lightly in appearing to challenge him, because I rarely disagree with him.
I agree that a 10 hour PPL should not be obsessing about very rare failures, and should have their mind on what is being taught. Detracting from a lesson by going off on a protracted tangent, well beyond the instructor's reply, is not what you should do during training. Follow the lesson as taught, and keep your mind on the job. Big Pistons is right, you do not need to know what to do about a control jam, at this stage in your flying.
However, if in your desire to become a pilot with deeper knowledge, you ask questions of your instructor, which do not detract from training, I think that you are entitled to a reasonable answer. This particular subject is deep, in that it is rare, (which is what most of us told you first), but when it happens, it can be really bad.
Your instructor knows for certain, that as long as you fly the planes you are assigned, preflight as taught (and don't fly if you detect or suspect a defect), and don't zero G them, you are not going to have a control jam. How do I know that your instructor knows this? I just do, 36 years of flying tells you some things....
If you're obsessing about control jams - stop it. If you're genuinely interested in the design of systems in aircraft and what is required and what is not, and why, because you would like to deepen your knowledge about aircraft, and in doing so, you are not detracting from your training (frustrating your instructor), I can (and have) support that. It's what you do with what you know.
If you are asking your instructor lots of questions outside the scope of your training pay for the extra training time. It's only fair....
You have asked questions here which could be beyond the knowledge/experience depth of some new instructors. Doing that is not a crime, as long as you remember that no pilot likes to have their authority, skill, or capability challenged by a 10 PPL student! Tread lightly, and be diplomatic. Perhaps you have asked the right question the wrong way here, and on AvCanada. Maybe you meant to ask: "has anyone had any experience with jammed controls, and what did they learn from that experience to make them a more safe pilot?". I don't mean to put words in your mouth, but with that wording, everyone can keep their pride!
I will disagree with Big Pistons on one thing though.... Don't PM Memphis Belle, we'd just have two bitter PPRuNers then!
