Ultimate Load for Bridges using Structural Carbon Steel Solution

Follow our step by step solution on how to calculate Ultimate Load for Bridges using Structural Carbon Steel?

FIRST Step Consider the formula

P u = (26500 - 0.425 \cdot {L|r}^{2}) \cdot A

Next Step Substitute values of Variables

∴

P u = (26500 - 0.425 \cdot 140^{2}) \cdot 81in²

Next Step Convert Units

∴

P u = (26500 - 0.425 \cdot 140^{2}) \cdot 0.0523m²

Next Step Prepare to Evaluate

∴

P u = (26500 - 0.425 \cdot 140^{2}) \cdot 0.0523

Next Step Evaluate

∴

P u = 430.698262740468kg

Next Step Convert to Output's Unit

∴

P u = 949.527133207597lbs

LAST Step Rounding Answer

∴

P u = 949.5271lbs
