Allowable Stress for Compression Elements for Highway Bridges Solution

Follow our step by step solution on how to calculate Allowable Stress for Compression Elements for Highway Bridges?

FIRST Step Consider the formula

σ allowable = 0.44 \cdot f y

Next Step Substitute values of Variables

∴

σ allowable = 0.44 \cdot 250MPa

Next Step Convert Units

∴

σ allowable = 0.44 \cdot 2.5E+8Pa

Next Step Prepare to Evaluate

∴

σ allowable = 0.44 \cdot 2.5E+8

Next Step Evaluate

∴

σ allowable = 110000000Pa

Next Step Convert to Output's Unit

∴

σ allowable = 110000000N/m²

LAST Step Rounding Answer

∴

σ allowable = 1.1E+8N/m²
