1. What is the Deflection Angle of Central Curve?

The Deflection Angle of Central Curve is the angle between the onward extension of the previous leg and the line ahead in a curved path or roadway design.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( D2 \) — Deflection Angle of Central Curve (degrees)
• \( D1 \) — Deflection Angle of Entrance Curve (degrees)

Explanation: This formula calculates the central curve deflection angle by subtracting the entrance curve deflection angle from 35 degrees.

3. Importance of Deflection Angle Calculation

Details: Accurate calculation of deflection angles is crucial for proper roadway design, ensuring smooth transitions between straight sections and curves, and maintaining safe vehicle navigation.

4. Using the Calculator

Tips: Enter the Deflection Angle of Entrance Curve in degrees. The value must be a valid number (≥0).

5. Frequently Asked Questions (FAQ)

Q1: What is the typical range for deflection angles?
A: Deflection angles typically range from 0 to 35 degrees, depending on the specific roadway design requirements.

Q2: Why is 35 degrees used as the constant in this formula?
A: 35 degrees is a standard value used in certain roadway design calculations to maintain proper curvature and transition between road segments.

Q3: Can this formula be used for all types of curves?
A: This specific formula is designed for particular curve configurations. Always consult relevant design standards for specific applications.

Q4: What units should be used for input values?
A: All angle measurements should be entered in degrees for this calculator.

Q5: How precise should the deflection angle measurements be?
A: For engineering applications, deflection angles are typically measured with precision up to 0.01 degrees for accurate design calculations.
