Moments given Extrados Stresses on Arch Dam Solution

Follow our step by step solution on how to calculate Moments given Extrados Stresses on Arch Dam?

FIRST Step Consider the formula

M t = σ e \cdot t \cdot t + F \cdot \frac{t}{6}

Next Step Substitute values of Variables

∴

M t = 25N/m² \cdot 1.2m \cdot 1.2m + 63.55N \cdot \frac{1.2m}{6}

Next Step Convert Units

∴

M t = 25Pa \cdot 1.2m \cdot 1.2m + 63.55N \cdot \frac{1.2m}{6}

Next Step Prepare to Evaluate

∴

M t = 25 \cdot 1.2 \cdot 1.2 + 63.55 \cdot \frac{1.2}{6}

Next Step Evaluate

∴

M t = 48.71J

LAST Step Convert to Output's Unit

∴

M t = 48.71N*m
