Length of Summit Curve for Stopping Sight Distance when Curve Length is less than SSD Solution

Follow our step by step solution on how to calculate Length of Summit Curve for Stopping Sight Distance when Curve Length is less than SSD?

FIRST Step Consider the formula

L Sc = 2 \cdot SSD - (\frac{{({(2 \cdot H)}^{0.5} + {(2 \cdot h)}^{0.5})}^{2}}{N})

Next Step Substitute values of Variables

∴

L Sc = 2 \cdot 160m - (\frac{{({(2 \cdot 1.2m)}^{0.5} + {(2 \cdot 0.15m)}^{0.5})}^{2}}{0.08})

Next Step Prepare to Evaluate

∴

L Sc = 2 \cdot 160 - (\frac{{({(2 \cdot 1.2)}^{0.5} + {(2 \cdot 0.15)}^{0.5})}^{2}}{0.08})

Next Step Evaluate

∴

L Sc = 265.036796564404m

LAST Step Rounding Answer

∴

L Sc = 265.0368m
