The distance between e.g. of compression and e.g. of tension flanges of a plate girder, is known as

overall depth

clear depth

effective depth

none of these.

[#]

The failure of a web plate takes place by yielding if the ratio of the clear depth to thickness of the web, is less than

[#]

The cross-section of a standard fillet is a triangle whose base angles are

45° and 45°

30° and 60°

40° and 50°

20° and 70°

[#]

For the steel member exposed to weather and accessible for repainting, the thickness of steel should not be less than (excepting the webs of Indian Standard rolled steel joists and channels).

4 mm

6 mm

8 mm

10 mm

[#]

The effective length of a compression member of length L held in position and restrained in direction at one end and effectively restrained in direction but not held in position at the other end, is

0.67 L

0.85 L

1.5 L

2 L

[#]

The minimum edge distance of a rivet line connecting two or more plates, is kept equal to 37 mm plus (where t is the thickness in mm of the thinner outside plate).

2 t

4 t

6 t

8 t

10 t

[#]

The most commonly used sections in lateral system to carry shear force in built up columns, are

rolled steel flats

rolled angles

rolled channels

all the above.

[#]

In a grillage column footing maximum bending moment M occurs at the centre of grillage beams. Its value is (where P, L and a are axial load, length of the beam and length of the column base respectively).

M = P(L - a)

[#]

In a member subjected to an axial tensile force and bending moment, the maximum allowable stress in axial tension is f_t and the maximum allowable bending stress in tension is f_ht. If f_t and f_ht are their corresponding actual axial tensile and bending stresses, the relationship which holds goods is
