Sight Distance More than Length of Summit Curve Solution

Follow our step by step solution on how to calculate Sight Distance More than Length of Summit Curve?

FIRST Step Consider the formula

S = (\frac{L s}{2}) + \frac{{(\sqrt{2 \cdot h 1} + \sqrt{2 \cdot h 2})}^{2}}{2 \cdot N}

Next Step Substitute values of Variables

∴

S = (\frac{94.7208m}{2}) + \frac{{(\sqrt{2 \cdot 32.5m} + \sqrt{2 \cdot 55m})}^{2}}{2 \cdot 70.9388°}

Next Step Convert Units

∴

S = (\frac{94.7208m}{2}) + \frac{{(\sqrt{2 \cdot 32.5m} + \sqrt{2 \cdot 55m})}^{2}}{2 \cdot 1.2381rad}

Next Step Prepare to Evaluate

∴

S = (\frac{94.7208}{2}) + \frac{{(\sqrt{2 \cdot 32.5} + \sqrt{2 \cdot 55})}^{2}}{2 \cdot 1.2381}

Next Step Evaluate

∴

S = 186.327701334855m

LAST Step Rounding Answer

∴

S = 186.3277m
