- A square column carries a load P at the centroid of one of the quarters of the square. If a is the side of the main square, the combined bending stress will be
- The eccentricity (e) of a hollow circular column, external diameter 25 cm, internal diameter 15 cm for an eccentric load 100 t for non-development of tension, is
- At any point of a beam, the section modulus may be obtained by dividing the moment of inertia of the section by
- Pick up the correct statement from the following:
- For determining the support reactions at A and B of a three hinged arch, points B and Care joined and produced to intersect the load line at D and a line parallel to the load line through A at D’. Distances AD, DD’ and AD’ when measured were 4 cm, 3 cm and 5 cm respectively. The angle between the reactions at A and B is
- If E, N, K and 1/m are modulus of elasticity, modulus of rigidity. Bulk modulus and Poisson ratio of the material, the following relationship holds good
- The horizontal deflection of a parabolic curved beam of span 10 m and rise 3 m when loaded with a uniformly distributed load l t per horizontal length is (where Ic is the M.I. at the crown, which varies as the slope of the arch).
- In case of a simply supported rectangular beam of span L and loaded with a central load W, the length of elasto-plastic zone of the plastic hinge, is
- In case of a simply supported I-section beam of span L and loaded with a central load W, the length of elasto-plastic zone of the plastic hinge, is
- A bar L metre long and having its area of cross-section A, is subjected to a gradually applied tensile load W. The strain energy stored in the bar is

A.
The structural member subjected to compression and whose dimensions are small as compared to its length, is called a stmt |
|
B.
The vertical compression members are generally known as columns or stanchions |
|
C.
Deflection in lateral direction of a long column, is generally known as buckling |
