A rectangular column of 230mm x 350mm and 4M long used as a column. If one end is hinged and other is fixed, find the safe load the column can carry if FOS-2.5. use Euler’s formula. E=200Gpa

Note: Moment of Inertia of the section will be least. Before solving the problem always use effective length in the formula; which will get by using below table

Actual length of column = L, Effective length = Le

$A = 230 \times 350 \ mm^2, \ L = 4 m = 4000 \ mm, \ F.O.S = 2.5, E = 200 \ Gpa$

Effective length of column Le is $\frac{L}{\sqrt{2}} = \frac{4000}{\sqrt{2}} = 2828.42 \ mm$
