1. What is the Exact Length of Curve Formula?

The Exact Length of Curve formula calculates the arc length in a parabolic curve based on the central angle and degree of curve. It is commonly used in civil engineering and road design to determine the precise length of curved sections.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( L_c \) — Length of Curve (meters)
• \( I \) — Central Angle of Curve (radians)
• \( D \) — Degree of Curve (radians)

Explanation: The formula calculates the arc length by multiplying the central angle by 100 and dividing by the degree of curve, providing an exact measurement of the curve's length.

3. Importance of Length of Curve Calculation

Details: Accurate calculation of curve length is essential for proper road design, construction planning, and ensuring safe transportation infrastructure. It helps in determining material quantities and construction costs.

4. Using the Calculator

Tips: Enter the central angle of curve and degree of curve in radians. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)
