Euler's formula is not valid for mild steel column when slenderness ratio is

ALess than 80

BMore than 80

CMore than 120

Dore than 30

Answer:

A. Less than 80

Read Explanation:

Euler's formula is valid only for long columns with slenderness ratio greater than or equal to critical slenderness ratio. For mild steel, when slenderness ratio is less than 80, the Euler's theory is not applicable.
