Solution:

QUESTION: 8

The column of length 240 cm, area of cross- section 20 cm 2, moment of inertia 1_{XX} = 720 cm^{4} and I_{yy} = 80 cm^{4} is subject to buckling load. The data corresponds to slenderness ratio

Solution:

and

Slenderness ratio is the ratio of length and least radius of gyration

∴

QUESTION: 9

The slenderness of a column is zero when

Solution:

QUESTION: 10

A column of rectangular cross-section (I_{XX} > I_{YY}) is subject to an axial load. What is the axis about which the column will have atendency to buckle?

Solution:

Buckling tendency is always along least radius of gyration.
