41. Bending moment at any section in a conjugate beam gives in the actual beam

deflection

42. For a two-hinged arch, if one of the supports settles down vertically, then the

horizontal thrust remains unchanged

43. For a symmetrical two hinged parabolic arch, if one of the supports settles horizontally, then the horizontal thrust is decreased

44. A single rolling load of 8 kN rolls along a girder of 15 m span. The absolute maxi

mum bending moment will be 30 kN m

45. The maximum bending moment due to a train of wheel loads on a simply supported girder always occurs under a wheel load

46.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

47.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

48.When a series of wheel loads crosses a simply supported girder, the maximum

bending moment under any given wheel load occurs when the centre of span is midway between the centre of gravity of the load system and the wheel load under consideration

49.Which of the following is not the displacement method ?

Column analogy method

50. The Muller-Breslau principle can be used to determine the shape of the influence line, indicate the parts of the structure to be loaded to obtain the maximum effect,calculate the ordinates of the influence lines

if the axial deformation is ignored? 3

58.What is the degree of kinematic indeterminacy of the frame shown in Fig. 12.11,

if the axial deformation is ignored ? 8

59.What is the degree of static indeterminacy of the beam shown in Fig. 12.12 ? 2

60.The portal frame shown in Fig. 12.13 will sway towards right
