20
30
40
Euler's theory is applicable only for:
Short columns
Long, slender columns

Which of the following will increase the Euler buckling load?
Increasing effective length
Reducing modulus of elasticity

Reducing cross-sectional area
A long column fails primarily by:
Shear
Torsion
Buckling
Crushing
Which of the following end condition gives maximum load-carrying capacity for a column of given material and cross-section?
Both ends hinged
Both ends fixed

1L
2L
Higher slenderness ratio indicates that the column is more prone to:
Crushing failure
Buckling failure
Shear failure
Fatigue failure
Euler's formula shows that the critical load is inversely proportional to:

Equal
Two times greater
Four times greater
Half
Which of the following conditions is critical for a long axially loaded column?

For a long column, as the effective length increases, the critical buckling load
Increases
Decreases
Remains constant
Becomes zero
If eccentricity of load is zero, the stress in a short column is:
Bending stress
Pure axial compressive stress
Shear stress
Torsional stress
For a short axially loaded column, the stress distribution over the cross-section is assumed to be:
Uniform
Linear
Parabolic
Circular
The effective length of a column depends on:
Load intensity
Load intensity
End conditions
Cross-section shape
The main difference between a column and a strut is:
Column is always vertical, strut may be inclined
Column carries axial compression, strut carries bending
Column is slender, strut is short
Column is tensioned, strut is compressed

All struts are columns, but all columns are not struts
Columns and struts are the same
A strut always resists tensile load
