1. What is Horizontal Distance of C.G. from Rear Axle?

The Horizontal Distance of C.G. from Rear Axle is the distance from the center of gravity to the rear axle, which significantly affects the racing car's stability during rear wheel braking operations.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ x = R_R \times \frac{b + \mu_{RW} \times h}{W \times \cos(\theta)} - \mu_{RW} \times h \]

Where:

\( x \) — Horizontal Distance of C.G. from Rear Axle (m)
\( R_R \) — Normal Reaction at Rear Wheel (N)
\( b \) — Vehicle Wheelbase (m)
\( \mu_{RW} \) — Friction Coefficient on Rear Wheel
\( h \) — Height of C.G. of Vehicle (m)
\( W \) — Vehicle Weight (N)
\( \theta \) — Road Inclination Angle (rad)

Explanation: This formula calculates the horizontal distance from the center of gravity to the rear axle, considering various factors including friction coefficient, vehicle weight, and road inclination.

3. Importance of Horizontal Distance Calculation

Details: Accurate calculation of this distance is crucial for optimizing vehicle stability, braking performance, and overall handling characteristics in racing conditions.

4. Using the Calculator

Tips: Enter all values in appropriate units (meters for distances, Newtons for forces, radians for angles). Ensure all values are positive and valid for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: Why is this distance important in racing cars?
A: This distance affects weight distribution, braking efficiency, and overall vehicle stability during high-speed maneuvers and braking.

Q2: How does road inclination affect the calculation?
A: Road inclination changes the effective weight distribution and normal forces on the wheels, which directly impacts the calculated distance.

Q3: What is the typical range for this distance in racing cars?
A: The distance varies depending on vehicle design but is typically optimized for balanced weight distribution and optimal handling characteristics.

Q4: How does friction coefficient affect the result?
A: Higher friction coefficients generally result in different weight transfer characteristics during braking, affecting the calculated distance.

Q5: Can this formula be used for other vehicle types?
A: While primarily designed for racing cars, the principles can be applied to other vehicle types with appropriate modifications for specific characteristics.
