Balanced | Under Reinforced | Over reinforced | RCC Sections

There are 3 types of RCC sections Balanced, under reinforced and over reinforced sections
In Balanced Section crushing strain in concrete reaches yielding of steel simultaneously, in Under Reinforced section yielding of steel starts first and than it reaches crushing strain in concrete, in over reinforced sections crushing of concrete starts first than yielding of steel.
In balanced section failure occurs simultaneously and is called balanced or critical failure.
In under reinforced sections failure occurs by yielding of steel and is called as primary tension failure.
In over reinforced sections failure occurs by crushing of concrete and is called primary compression failure.
Design codes prohibits over reinforced design as concrete is brittle and brittle failure will not give sufficient warning before failure because it is primary compression failure

    Hii when lets assume in T section which is under reinforced depth of N.A. from extreme compression fiber is 50 mm (maximum compresive strain is 0.0035) and depth of centre of tension reinforcement from NA is 500 mm(thus by compatibility of strain tensile strain will be 10 times maximum compresive strain) is that much strain allowed?

    Please explain, in the case of under-reinforced beam vs the rest, how is it that the ability to visualize excessive stress in concrete beams is better that the ability to support such stress? Let's say an under reinforced concrete beam will start to bend to support 10 tonnes of stress, while the over reinforced beam will be able to support 12 Tons of stress comfortably, if the load is 12 Tons, how is the under-reinforced beam better performed when it clearly failed?

    While engineers design against failure, I have learnt they design things to "safely" fail too. An under-reinforced beam failing on applied 10 tonnes load fails by yielding gradually, using up all the ductile properties of the steel in tensile region, this makes it easier to detect it's failing and allows engineers to act on correcting the structure before it completely fails. But a 12 tonnes capacity over-reinforced beam will fail suddenly if it exceeds capacity making it very dangerous to use.

    In this case, I'm still not able to get difference between all three sections. I meant to say is if I provide 3 bar in bottom and 2 or 3 bar in top also, will be that be an over reinforced section ? Does Ast play any role in deciding the type of section ? And in your balanced section, what if I provide 2/3 bars in top also ?
