Question

Assertion (A): The buckling load for a column of specified material, cross-section and end conditions calculated as per Euler's formula varies inversely with the column length.
Reason (R): Euler's formula takes into account the end conditions in determining the effective length of column.

• A. both A and R are true and R is the correct explanation of A
• B. both A and R are true but R is not a correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

Answer 1

The correct option is D A is false but R is true

The buckling load varies inversely with the square of effective length i.e.,
$P=\frac{{\pi }^{2}EI}{l_e^2}$
