Actual answer is ml2. |

It's option B. Flexural rigidity is EI having Nm^2 units. |

Snehal Wankhede said: (Sep 2, 2016) | |

Option B. Flexural rigidity = EI = Nmm2 = ML3T-2. |

Sadashiva said: (Jan 14, 2017) | |

EI = ML^-1T^-2xL^4. |

Balia Ucp said: (Mar 14, 2017) | |

Here, EI = [ML^3T ^-2]. |

Mahadev said: (Mar 20, 2017) | |

@Snehal and @Balia is correct. E=N/m ^2, I=m^4. N=mass * gravity = Kg * m/sec. = ML^3/T. |

Poobathy said: (Jun 29, 2017) | |

Options A correct. |

Roy said: (Sep 27, 2017) | |

B is the right answer. |

Phani said: (Mar 10, 2018) | |

(Kg-m/s^2)*1/m = kg/s^2 = MT^-2. |

S K Jha said: (Sep 10, 2020) | |

EI = Nm2 = MLT-2 x L2 = ML3T-2. |

In a beam, the flexural rigidity (EI) varies along the length as a function of x as shown in the equation: Where E is the young's modulus (in Pasual, Pa), I is the second moment of area (in m4). Y is the traverse displacement of the beam x and M(x) is the bending moment at x. The SI unit of flexural rigidity is thus Pa. m4 or Nm4. So, the Dimension is ML3T-2 |

Khan said: (Jul 16, 2021) | |

E = N/m^2 & I= m^4. EI = N-m^2, N = Kg-m/s^2, EI = (Kg-m/s^2)*(m^2), EI = Kg-m^3/s^2= ML^3S^-2. |
