Pick up the correct statement from the following:
-
The ratio of longitudinal stress to strain within eiastic limit, is known as
-
If flexural rigidity of a column whose length is L and the loaded end is free, is El, the critical load will be
-
For a column of height L fixed in position and direction both at its top and bottom, its effective length, is
-
In a tension member if b is width of plate, t is thickness of plate, p is staggered pitch, g is gauge distance, n is number of rivet holes in zig-zag line, n is number of gauge spaces, d is gross diameter of rivets, then the net sectional area Anet of the plate, is
-
Net sectional area of a tension member, is equal to its gross section area
-
The distance measured along one rivet line from the centre of a rivet to the centre of adjoining rivet on an adjacent parallel rivet line, is called

A.
When the gauge distance is larger than the pitch, the failure of the section may occur in a zig-zag line
|
|
B.
When the gauge distance is smaller than the pitch, the failure of the section may occur in a straight right angle section through the centre of rivet holes
|
|
C.
When the gauge distance and pitch are both equal, the failure to the section becomes more likely as the diameter of the holes increases
|
|
D.
All the above.
