Critical Buckling Stress when Slenderness Parameter is greater than 2.25 Solution

STEP 0: Pre-Calculation Summary

Formula Used

Critical Buckling Stress = (0.877*Yield Stress of Steel)/Slenderness Parameter
F_cr = (0.877*F_y)/λ_c
This formula uses 3 Variables

Variables Used

Critical Buckling Stress - (Measured in Pascal) - Critical Buckling Stress is the maximum stress that can be taken by the section without failure. Any stress surpassing the critical stress makes the section, say, column to failure.
Yield Stress of Steel - (Measured in Pascal) - Yield Stress of Steel is the stress at which the material begins to deform plastically, meaning it will not return to its original shape when the applied force is removed.
Slenderness Parameter - Slenderness Parameter is the value which demarcates between the elastic and inelastic behavior of the member.

STEP 1: Convert Input(s) to Base Unit

Yield Stress of Steel: 250 Megapascal --> 250000000 Pascal (Check conversion here)
Slenderness Parameter: 2.25 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F_cr = (0.877*F_y)/λ_c --> (0.877*250000000)/2.25

Evaluating ... ...

F_cr = 97444444.4444444

STEP 3: Convert Result to Output's Unit

97444444.4444444 Pascal -->97.4444444444444 Megapascal (Check conversion here)

FINAL ANSWER

97.4444444444444 ≈ 97.44444 Megapascal <-- Critical Buckling Stress
