1. What is Centrifugal Ratio?

The Centrifugal Ratio is defined as the ratio of centrifugal force to weight of vehicle. It's an important parameter in vehicle dynamics and road design to ensure safe turning at various speeds.

2. How Does the Calculator Work?

The calculator uses the Centrifugal Ratio formula:

Where:

• \( V \) — Vehicle Velocity (km/h)
• \( RCurve \) — Curve Radius (m)
• \( g \) — Acceleration due to Gravity (m/s²)

Explanation: The formula calculates the ratio between centrifugal force experienced by a vehicle in a curve and its weight, helping determine the required banking angle for safe turning.

3. Importance of Centrifugal Ratio Calculation

Details: Accurate centrifugal ratio calculation is crucial for road design, vehicle safety analysis, and determining appropriate speed limits on curved roads to prevent rollover accidents.

4. Using the Calculator

Tips: Enter vehicle velocity in km/h, curve radius in meters, and acceleration due to gravity in m/s². Standard gravity is 9.8 m/s². All values must be positive.

5. Frequently Asked Questions (FAQ)

Q1: What is a safe centrifugal ratio value?
A: Typically, values below 0.3 are considered safe for most road conditions, while higher values may indicate potential rollover risk.

Q2: How does vehicle velocity affect centrifugal ratio?
A: Centrifugal ratio increases with the square of velocity, meaning doubling the speed quadruples the centrifugal ratio.

Q3: Why is curve radius important in this calculation?
A: Larger curve radii result in lower centrifugal ratios, making turns safer at higher speeds.

Q4: When is this calculation used in real-world applications?
A: This calculation is used in highway design, racetrack engineering, and vehicle safety testing to ensure safe turning capabilities.

Q5: Are there limitations to this formula?
A: This formula provides a simplified calculation and doesn't account for factors like tire friction, road banking, or vehicle suspension characteristics.
