1. What is Wheel Base Of Vehicle Given COG Position From Rear Axle?

This calculation determines the wheelbase of a vehicle based on the horizontal distance of the center of gravity from the rear axle, mass on the front axle, and total vehicle mass. It's essential for vehicle dynamics and stability analysis.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ b = \frac{c}{W_f / m} \]

Where:

\( b \) — Wheelbase of Vehicle (m)
\( c \) — Horizontal Distance of C.G. from Rear Axle (m)
\( W_f \) — Mass on Front Axle (kg)
\( m \) — Mass of Vehicle (kg)

Explanation: The formula calculates the wheelbase by dividing the horizontal distance from the center of gravity to the rear axle by the ratio of front axle mass to total vehicle mass.

3. Importance of Wheelbase Calculation

Details: Accurate wheelbase calculation is crucial for vehicle design, stability analysis, weight distribution optimization, and determining vehicle handling characteristics.

4. Using the Calculator

Tips: Enter horizontal distance in meters, mass on front axle in kilograms, and total vehicle mass in kilograms. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is wheelbase important in vehicle design?
A: Wheelbase affects vehicle stability, ride comfort, turning radius, and overall handling characteristics.

Q2: How does center of gravity position affect wheelbase calculation?
A: The horizontal distance from C.G. to rear axle directly influences the weight distribution and thus the calculated wheelbase.

Q3: What are typical wheelbase values for different vehicle types?
A: Wheelbase varies significantly - compact cars (2.4-2.7m), sedans (2.7-2.9m), SUVs (2.8-3.1m), trucks (3.5-4.5m+).

Q4: How does weight distribution affect vehicle performance?
A: Proper weight distribution between front and rear axles is crucial for traction, braking performance, and overall vehicle stability.

Q5: Can this calculation be used for all vehicle types?
A: This formula applies to most wheeled vehicles, though specialized vehicles may require additional considerations for accurate calculations.
