comment What is the cause of noise generation at my bike helmet
I've experienced this in a different way.. In my apartment, on a windy day one could hear a ghost-like noise with the windows closed. Open 'em a crack and it disappeared. Must be some resonance effect or something. (If you want, I can add this to the question)

comment Centripetal force of a rotating rigid body?
@Ryan see above, the force balances out cos the 'string' points in all directions.

comment Centripetal force of a rotating rigid body?
@Ryan: There is a net CPF on every individual small element of the roundabout. Overall, the CPFs add up to zero. CPF only applies to small elements-- for a larger body the internal forces come into the picture (these can be calculated easily, though). Also note: whenever a constant-magnitude force is centripetal, i.e. it changes its direction to point at a particular point, then there will be no net translational motion.

comment Centripetal force of a rotating rigid body?
@Ryan. There is. The tangential pushing accelerates the roundabout and puts it in UCM in the first place. Then, the metal of the roundabout does the same thing as a rope-it keept is in UCM.

@Pygmalion it's valid. Why not? Can you find an exact duplicate?

comment How fictitious are fictitious forces?
@NickKidman: Oh, I see. I'll edit that out of my answer as well. :) EDIT: Seems like I've phrased it correctly anyway Newton's definition of a force is only valid in an inertial frame :D

comment How fictitious are fictitious forces?
@NickKidman: Could you clarify that? (for one, you haven't logically defined $f$). And $\vec F\neq\frac{\mathrm d\vec p}{\mathrm dt}$ in a non-inertial frame, so Newton's laws are obviously invalid there.

+1 for explaining the friction/etc aspect of it clearer than I did :)
