d= √ M/1000Q is the correct answer. |

How it is possible? Explain. |

Garry said: (Oct 12, 2017) | |

According to me, both C and D can be correct. |

E is correct. In this 100 is breadth in cm. |

Moment Resistance M = Qd^2. M/(10x10) = Qd^2. d = √M/100Q. So option E is correct. |

None of the above is the correct answer. According to me, M= Qbd^2. Here, ignoring b. M= Qd^2. So, d= √(M/Q). Now M is given in kg.cm. And 1kg = 9.81N or roughly 10N, and 1cm = 10mm. Therefore; 1kg.1cm = 10N.10mm =100Nmm. So, d= √(100M/Q) = 10 √(M/Q). |

What is Q here? |

Rajveer said: (Jan 4, 2020) | |

M = 0.138Fckbd*2. M = Qd*2(0.138fckb , M.R.factor), So, option C is correct. |

Moment of resistance/maximum B.M. (M) = QBd2. Where, Q = Moment resistacne factor. B = width of slab = 1 m = 100 cm, [since m was given in kg.cm], D = depth of slab. √ M = Q * 100 * d^2 (kg-cm). |

If we want M in N-mm then. 1kg=10N. 1cm=10mm. Then if we consider B as a unit dimension and ignore it we will come to. D=10√(M/Q). |
