FIRST Step Consider the formula

L max = W L \cdot \frac{S}{z \cdot I}

Next Step Substitute values of Variables

∴

L max = 43.47kN \cdot \frac{2.3m}{0.0125m³ \cdot 16m}

Next Step Convert Units

∴

L max = 43470N \cdot \frac{2.3m}{0.0125m³ \cdot 16m}

Next Step Prepare to Evaluate

∴

L max = 43470 \cdot \frac{2.3}{0.0125 \cdot 16}

Next Step Evaluate

∴

L max = 499905N

LAST Step Convert to Output's Unit

∴

L max = 499.905kN
