Allowable Bending Stress in Compression Flange Solution

Follow our step by step solution on how to calculate Allowable Bending Stress in Compression Flange?

FIRST Step Consider the formula

F b' = F b \cdot R pg \cdot R e

Next Step Substitute values of Variables

∴

F b' = 3MPa \cdot 0.64 \cdot 0.9813

Next Step Prepare to Evaluate

∴

F b' = 3 \cdot 0.64 \cdot 0.9813

Next Step Evaluate

∴

F b' = 1884096Pa

Next Step Convert to Output's Unit

∴

F b' = 1.884096MPa

LAST Step Rounding Answer

∴

F b' = 1.8841MPa
