Q:

A) Resistance of member | B) Stiffness of member |

C) Capacity of member | D) Potential of member |

Answer & Explanation
Answer: B) Stiffness of member

Explanation: When a structural member of the uniform section is subjected to a moment at one end only, then the moment required so as to rotate that end to produce a unit slope, is called stiffness of the member. Stiffness is basically a measure of the ability of the member to resist rotational deformation.

Q:

A) True | B) False |

Answer & Explanation
Answer: A) True

Explanation: The moment distribution method developed by Hardy Cross in 1930 is useful for analysis of indeterminate beams and frames. The method considers the flexural effect and ignores any effect caused due to shear and axial loadings.

Q:

A) The moment applied at one end to cause unit slope at the support | B) The additional moment applied at one end to completely resist the rotation caused due to external loading |

C) The moment developed or induced at one end due to a moment at another end | D) The moment applied at one end to cause unit slope at another end |

Answer & Explanation
Answer: C) The moment developed or induced at one end due to a moment at another end

Explanation: Carryover Moment is defined as the moment developed or induced at one end due to a moment at another end. It is useful in calculating stiffness factor and moment distribution for a particular joint.

Q:

A) 0 | B) 1 |

C) 2 | D) 3 |

Answer & Explanation
Answer: B) 1

Explanation: In internal pin support, there is only one possibility of deflection, so no degree of freedom is counted.
