1. What is Turn Radius?

Turn radius is the minimum radius of the circle a vehicle can make when turning at a specific steering angle. It's a critical measurement for vehicle design, road planning, and determining a vehicle's maneuverability.

2. How Does the Calculator Work?

The calculator uses the turn radius formula:

Where:

• \( R \) — Turn radius (m)
• \( WB \) — Wheelbase (m)
• \( \theta \) — Steer angle (degrees)

Explanation: The formula calculates the turning circle radius based on the vehicle's wheelbase and the steering angle of the wheels.

3. Importance of Turn Radius Calculation

Details: Understanding turn radius is essential for vehicle design, road infrastructure planning, parking lot design, and determining a vehicle's maneuverability in tight spaces.

4. Using the Calculator

Tips: Enter wheelbase in meters and steer angle in degrees. The steer angle must be between 0 and 90 degrees (exclusive).

5. Frequently Asked Questions (FAQ)

Q1: What factors affect a vehicle's turn radius?
A: Wheelbase, steering angle, tire size, and suspension design all affect a vehicle's turning capabilities.

Q2: Why is turn radius important for road design?
A: Road designers need to ensure that curves and intersections can accommodate the turning requirements of various vehicles.

Q3: How does wheelbase affect turn radius?
A: Longer wheelbase vehicles typically have larger turn radii, making them less maneuverable in tight spaces.

Q4: What's the difference between turn radius and turning circle?
A: Turn radius is half the diameter of the turning circle, which represents the full circle a vehicle makes when turning.

Q5: Are there other factors that affect real-world turning performance?
A: Yes, factors like tire grip, suspension geometry, and vehicle speed also affect how a vehicle actually turns in real conditions.
