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

The Horizontal Distance of C.G. From Rear Axle is the distance of vehicle's center of gravity (C.G.) from rear axle measured along wheelbase of vehicle. It is a critical parameter in vehicle dynamics and stability analysis.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ x = (b - \mu_0 \times h) \times \left(1 - \frac{R_r}{W \times \cos(\theta)}\right) \]

Where:

\( x \) — Horizontal Distance of C.G. From Rear Axle BFW (m)
\( b \) — Vehicle Wheelbase BFW (m)
\( \mu_0 \) — Friction Coefficient For Smooth Road BFW
\( h \) — Height of C.G of Vehicle BFW (m)
\( R_r \) — Normal Reaction at Rear Wheel BFW (N)
\( W \) — Vehicle Weight BFW (N)
\( \theta \) — Road Inclination Angle BFW (rad)

Explanation: This formula calculates the horizontal distance of the center of gravity from the rear axle, taking into account vehicle parameters and road conditions.

3. Importance of C.G. Distance Calculation

Details: Accurate calculation of C.G. position is crucial for vehicle stability analysis, braking performance evaluation, and overall vehicle safety design.

4. Using the Calculator

Tips: Enter all required parameters with appropriate units. Ensure values are valid (positive values, wheelbase > 0, vehicle weight > 0, etc.).

5. Frequently Asked Questions (FAQ)

Q1: Why is C.G. position important in vehicle dynamics?
A: The position of the center of gravity affects vehicle stability, weight distribution, braking performance, and handling characteristics.

Q2: How does road inclination affect the calculation?
A: Road inclination changes the normal force distribution and affects the weight transfer during braking, which is accounted for in the formula.

Q3: What is the significance of friction coefficient?
A: The friction coefficient represents the grip between tires and road surface, which influences braking performance and weight transfer.

Q4: Can this formula be used for all vehicle types?
A: While the basic principles apply to most vehicles, specific vehicle configurations may require additional considerations.

Q5: How accurate is this calculation?
A: The calculation provides a theoretical estimation. Actual vehicle dynamics may vary based on specific conditions and vehicle characteristics.
