## Q55. | ## A beam fixed at the and subjected to lateral loads only is statically indeterminate and degree of indeterminacy is ------- . |

1) | 1 | 2) | 2 |

3) | 3 | 4) | 4 |

5) | None of these |

**Answer : 2**

**Explanation :**Number of equations = 2

Number of reactions = 4

so, Indeterminacy = 4 -2 = 2

## Q56. | ## A cantilever beam of span L is subjected to a downward load of 800 kN uniformly distributed over its length and a concentrated upward load P at its free end. For vertical displacement to be zero at the free end, the value of P is -----. |

1) | 300 kN | 2) | 500 kN |

3) | 800 kN | 4) | 1000 kN |

5) | None of these |

**Answer : 300 kN**

**Explanation :**PL

^{3}/3EI = wL

^{4}/8EI

So, P = 3/8 (wl) =( 3/8) x 800 = 300 kN
