GATE ME 1994 | Columns and Struts Question 7 | Strength of Materials

GATE ME 1994

MCQ (Single Correct Answer)

-0.3

For the case of a slender column of length $$l,$$ and flexural rigidity $$EI$$ built-in at its base and free at the top, the Euler’s critical buckling load is

$${{4{\pi ^2}EI} \over {{l^2}}}$$

$${{2{\pi ^2}EI} \over {{l^2}}}$$

$${{{\pi ^2}EI} \over {{l^2}}}$$

$${{{\pi ^2}EI} \over {4{l^2}}}$$

GATE ME 1988

MCQ (Single Correct Answer)

-0.3

If the length of a column is doubled, the critical load becomes:

$${1 \over 2}$$ of the original valu

$${1 \over 4}$$ of the original value

$${1 \over 8}$$ of the original value

$${1 \over 16}$$ of the original value
