1-Dont try to cram or spend more time here just read it fast and cover syllabus then practice MCQ's cheptor of same topic to check your progress. . |
2-Wrong options are also given but dont concentrate there, Right answer is in bold format. |
Q21 ⇒ The method of virtual work in the analysis of
structures results is Equilibrium of forces [other wrong options] [Discuss in forum] Compatible deformations Stress strain relations None of these |
Q22 ⇒ In column analogy method, the area of an analogous column for a fixed beam of span L and flexural rigidity El is taken as L/EI [other wrong options] [Discuss in forum] L/2EI L/3EI L/4EI |
Q23 ⇒ The horizontal thrust due to rise in temperature
in a semicircular two-hinged arch of
radius R is proportional to 1/R2 [other wrong options] [Discuss in forum] R R2 1/R |
Q24 ⇒ The degree of static indeterminacy up to which column analogy method can be used is 3 [other wrong options] [Discuss in forum] 2 4 unrestricted |
Q25 ⇒ The deflection at any point of a perfect frame can be obtained by applying a unit load at the joint in the direction in which the deflection is required [other wrong options] [Discuss in forum] vertical direction horizontal direction inclined direction |
Q26 ⇒ The three moments equation is applicable only when there is no discontinuity such as hinges within the span [other wrong options] [Discuss in forum] the beam is prismatic there is no settlement of supports the spans are equal |
Q27 ⇒ While using three moments equation, a fixed end of a continuous beam is replaced by an additional span of zero length [other wrong options] [Discuss in forum] infinite length zero moment of inertia none of the above |
Q28 ⇒ The Castigliano's second theorem can be used to compute deflections for any type of structure [other wrong options] [Discuss in forum] in statically determinate structures only at the point under the load only for beams and frames only |
Q29 ⇒ Bending moment at any section in a conjugate beam gives in the actual beam deflection [other wrong options] [Discuss in forum] slope curvature bending moment |
Q30 ⇒ For a two-hinged arch, if one of the supports settles down vertically, then the horizontal thrust remains unchanged [other wrong options] [Discuss in forum] is increased is decreased becomes zero |
Q31 ⇒ For a symmetrical two hinged parabolic arch, if one of the supports settles horizontally, then the horizontal thrust is decreased [other wrong options] [Discuss in forum] is increased remains unchanged becomes zero |
Q32 ⇒ A single rolling load of 8 kN rolls along a girder of 15 m span. The absolute maximum bending moment will be 30 kN.m [other wrong options] [Discuss in forum] 8 kN.m 15 kN.m 60 kN.m |
Q33 ⇒ The maximum bending moment due to a train of wheel loads on a simply supported girder always occurs under a wheel load [other wrong options] [Discuss in forum] always occurs at center of span never occurs under a wheel load none of the above |
Q34 ⇒ When a uniformly distributed load, longer than the span of the girder, moves from left to right, then the maximum bending moment at mid section of span occurs when the uniformly distributed load occupies whole span [other wrong options] [Discuss in forum] less than the left half span whole of left half span more than the left half span |
Q35 ⇒ The thickness of each leaf of a cavity wall shall not be less than 7.5 cm [other wrong options] [Discuss in forum] 5 cm 10 cm 15 cm |
Q36 ⇒ When a uniformly distributed load, shorter than the span of the girder, moves from left to right, then the conditions for maximum bending moment at a section is that the load position should be such that the section divides the load in the same ratio as it divides the span [other wrong options] [Discuss in forum] the head of the load reaches the section the tail of the load reaches the section the load position should be such that the section divides it equally on both sides |
