Length of Curve when S is Less than L and h1 and h2 are same Solution

Follow our step by step solution on how to calculate Length of Curve when S is Less than L and h1 and h2 are same?

FIRST Step Consider the formula

L c = ((g 1) - (g 2)) \cdot \frac{{SD}^{2}}{800 \cdot h}

Next Step Substitute values of Variables

∴

L c = ((2.2) - (-1.5)) \cdot \frac{{490m}^{2}}{800 \cdot 1.7m}

Next Step Prepare to Evaluate

∴

L c = ((2.2) - (-1.5)) \cdot \frac{490^{2}}{800 \cdot 1.7}

Next Step Evaluate

∴

L c = 653.213235294118m

LAST Step Rounding Answer

∴

L c = 653.2132m
