Sample CE8402 Important 16 Mark Questions Strength Of Materials 2 SOM2

1.Define: Column and strut.
A column is a long vertical slender bar or vertical member, subjected to an axial
compressive load and fixed rigidly at both ends.
A strut is a slender bar or a member in any position other than vertical, subjected to a
compressive load and fixed rigidly or hinged or pin jointed at one or both the ends.
2. What are the types of column failure?
1. Crushing failure: CE8402 Important 16 Mark Questions Strength Of Materials 2 SOM2
The column will reach a stage, when it will be subjected to the ultimate crushing
stress, beyond this the column will fail by crushing The load corresponding to the crushing stress is
called crushing load. This type of failure occurs in short column.
2. Buckling failure:
This kind of failure is due to lateral deflection of the column. The load at which the
column just buckles is called buckling load or crippling load or critical load. This type of failure CE8402 Important 16 Mark Questions Strength Of Materials 2 SOM2
occurs in long column.
3. What is slenderness ratio ( buckling factor)? What is its relevance in column?
It is the ratio of effective length of column to the least radius of gyration of the cross
sectional ends of the column. CE8402 Important 16 Mark Questions Strength Of Materials 2 SOM2
Slenderness ratio = l eff / r
l eff = effective length of column r
= least radius of gyration
Slenderness ratio is used to differentiate the type of column. Strength of the column
depends upon the slenderness ratio, it is increased the compressive strength of the column decrease as
the tendency to buckle is increased.
4. What are the factors affect the strength column?
1.Slenderness ratio CE8402 Important 16 Mark Questions Strength Of Materials 2 SOM2
Strength of the column depends upon the slenderness ratio, it is increased the
compressive strength of the column decrease as the tendency to buckle is increased.
2. End conditions: Strength of the column depends upon the end conditions also. CE8402 Important 16 Mark Questions Strength Of Materials 2 SOM2
