A column of 6 m effective length is to be made from 3 plates as shown in fig. Using E=210GPa find the factor of safety with respect to buckling for an axial load of 17 kN. Use Euler’s Theory.

Data:

enter image description here

E = 210 Gpa

$E = 210 \times 10^3 \ Mpa$

Axial Load = 17 KN

$L_e = 6m = 6000 \ mm$

1] Moment of Inertia:

$I_{xx} = \frac{80 \times (120 + 10 + 10)^3}{12} - \frac{(80 – 20) \times 120^3}{12} = 9.65 \times 10^6 \ mm^4$

$I_{yy} …
