-
A 20 mm dia steel bar which is subjected to an axial tension of 2300 kg/cm2 produces a strain of 0.004 cm. If Young's modulus of steel is 2.1 x 106 kg/cm2, the bar is

Poisson's ratio for steel within elastic limit, ranges from
-
When a large value of radius of gyration is not required
-
The maximum axial load which is just sufficient to keep a column in a small deflected shape, is called
-
If the slenderness ratio is greater than 160, the allowable stress in axial compression is multiplied by a factor (1.2 - (l/xy) where x is
-
The effective length of a compression member of length L, held in position and restrained in direction at both ends, is
-
Spans of continuous fillers are considered approximately equal if the longest span does not exceed the shortest span by more than

The gross diameter of a rivet is the diameter of
