Critical Buckling Stress when Slenderness Parameter is Less than 2.25 Solution

Follow our step by step solution on how to calculate Critical Buckling Stress when Slenderness Parameter is Less than 2.25?

FIRST Step Consider the formula
Fcr=0.658λc⋅Fy
Next Step Substitute values of Variables
∴ Fcr=0.6582.25⋅250MPa
Next Step Convert Units
∴ Fcr=0.6582.25⋅2.5E+8Pa
Next Step Prepare to Evaluate
∴ Fcr=0.6582.25⋅2.5E+8
Next Step Evaluate
∴Fcr=97487350.9395608Pa
Next Step Convert to Output's Unit
∴Fcr=97.4873509395608MPa
LAST Step Rounding Answer
∴Fcr=97.4874MPa
