Buckling Stress for Q Factor Less than or Equal to 1 Solution

STEP 0: Pre-Calculation Summary

Formula Used

Buckling Stress = (1-(Factor Q/2))*Yield Strength of Steel
F_cr = (1-(Q_factor/2))*f_y
This formula uses 3 Variables

Variables Used

Buckling Stress - (Measured in Pascal) - Buckling Stress is the stress developed due to a sudden change in shape of a structural component under load, such as the bowing of a column under compression.
Factor Q - Factor Q is geometrical constant based on the material of the member.
Yield Strength of Steel - (Measured in Pascal) - Yield strength of steel is the level of stress that corresponds to the yield point.

STEP 1: Convert Input(s) to Base Unit

Factor Q: 0.014248 --> No Conversion Required
Yield Strength of Steel: 250 Megapascal --> 250000000 Pascal (Check conversion here)
