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

Follow our step by step solution on how to calculate Buckling Stress for Q Factor Less than or Equal to 1?

FIRST Step Consider the formula

F cr = (1 - (\frac{Q factor}{2})) \cdot f y

Next Step Substitute values of Variables

∴

F cr = (1 - (\frac{0.0142}{2})) \cdot 250MPa

Next Step Convert Units

∴

F cr = (1 - (\frac{0.0142}{2})) \cdot 2.5E+8Pa

Next Step Prepare to Evaluate

∴

F cr = (1 - (\frac{0.0142}{2})) \cdot 2.5E+8

Next Step Evaluate

∴

F cr = 248219000Pa

LAST Step Convert to Output's Unit

∴

F cr = 248.219MPa
