QUESTION: 1

### The rectangular column shown in the figure below carries a load P having eccentricities ‘ex’ and ' ey ’ along the x-axis and y-axis respectively. The stress at any point (*, y) is given by

Solution:

Stress at any point

QUESTION: 2

### Euler’s formula for a mild steel long column hinged  at both end is not valid for slenderness ratio

Solution:

According to Euler's theory,

For a mild steel coumn,
σy = 300 N/mm2 and
E = 2.1 x 105

Hence, when the slenderness ratio is less than this limit for mild steel columns , Euler’s formula will not be valid.

QUESTION: 3

### The buckling load for a column pinned at both ends is 10kN. If the ends are fixed, the buckling load changes to

Solution:

For both ends pinned,
= 4 x 10 = 40kN

QUESTION: 4

The radius of gyration of a rectangular section (depth d, width b) from a centroidal axis parallel to the width is

Solution:

QUESTION: 5

For no tension in column of diameter D, the eccentricity of the compressive load must be less than

Solution:

For no tension condition,

QUESTION: 6

The Rankine constant in the formula for axial loads on column made of material of crushing strength fc and modulus of elasticity E is

Solution:
