According to Euler's column theory, the crippling load for a column of length ($$l$$) with one end fixed and the other end hinged, is
A
$$\frac{{{\pi ^2}{\text{E}}I}}{{{l^2}}}$$
B
$$\frac{{{\pi ^2}{\text{E}}I}}{{4{l^2}}}$$
C
$$\frac{{2{\pi ^2}{\text{E}}I}}{{{l^2}}}$$
D
$$\frac{{4{\pi ^2}{\text{E}}I}}{{{l^2}}}$$
Correct Answer: $$\frac{{2{\pi ^2}{\text{E}}I}}{{{l^2}}}$$
