Allowable Unit Stress in Bending Solution

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

FIRST Step Consider the formula

F b = 0.55 \cdot f y

Next Step Substitute values of Variables

∴

F b = 0.55 \cdot 250MPa

Next Step Convert Units

∴

F b = 0.55 \cdot 2.5E+8Pa

Next Step Prepare to Evaluate

∴

F b = 0.55 \cdot 2.5E+8

Next Step Evaluate

∴

F b = 137500000N

LAST Step Convert to Output's Unit

∴

F b = 137500kN
