MCQ (Single Correct Answer)

-0.3

A pin-ended column of length $$L,$$ modulus of elasticity $$E$$ and second moment of the cross-sectional area $$I$$ is loaded centrally by a compressive load $$P.$$ The critical buckling load $$\left( {{P_{cr}}} \right)$$ is given by

$${P_{cr}} = {{EL} \over {{\pi ^2}{L^2}}}$$

$${P_{cr}} = {{{\pi ^2}EL} \over {3{L^2}}}$$

$${P_{cr}} = {{\pi EL} \over {{L^2}}}$$

$${P_{cr}} = {{{\pi ^2}EL} \over {{L^2}}}$$
