1. What is the Height of C.G. from Road Surface on Front Wheel?

The Height of C.G. from Road Surface on Front Wheel is the vertical distance of the center of gravity from the ground level of a racing car during rear wheel braking. It is a critical parameter that affects the vehicle's stability and braking performance.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ h = \frac{W \times (b - x) \times \cos(\theta)}{R_F} - b}{\mu_{FW}} \]

Where:

\( h \) — Height of C.G. of Vehicle (Meter)
\( W \) — Vehicle Weight (Newton)
\( b \) — Vehicle Wheelbase (Meter)
\( x \) — Horizontal Distance of C.G. from Rear Axle (Meter)
\( \theta \) — Road Inclination Angle (Radian)
\( R_F \) — Normal Reaction at Front Wheel (Newton)
\( \mu_{FW} \) — Friction Coefficient on Front Wheel

Explanation: The formula calculates the height of the center of gravity by considering the vehicle's weight distribution, wheelbase, road inclination, and frictional forces on the front wheel.

3. Importance of Height of C.G. Calculation

Details: Accurate calculation of the height of the center of gravity is crucial for optimizing the racing car's stability, handling, and braking performance, especially during high-speed maneuvers and braking scenarios.

4. Using the Calculator

Tips: Enter all values in the specified units. Ensure that Vehicle Weight, Vehicle Wheelbase, Normal Reaction at Front Wheel, and Friction Coefficient on Front Wheel are positive. Horizontal Distance of C.G. from Rear Axle and Road Inclination Angle should be non-negative.

5. Frequently Asked Questions (FAQ)

Q1: Why is the height of C.G. important in racing cars?
A: The height of the center of gravity affects the vehicle's roll stability, cornering performance, and overall handling, making it a critical parameter in racing car design and tuning.

Q2: How does road inclination affect the height of C.G. calculation?
A: Road inclination changes the normal forces on the wheels and the effective weight distribution, which in turn affects the calculated height of the center of gravity.

Q3: What is the significance of the friction coefficient in this formula?
A: The friction coefficient on the front wheel influences the braking force and the distribution of forces during braking, which is essential for accurate calculation of the height of C.G.

Q4: Can this formula be used for all types of vehicles?
A: This formula is specifically designed for racing cars during rear wheel braking. It may not be directly applicable to other vehicle types without modifications.

Q5: What are the units for the input parameters?
A: Vehicle Weight and Normal Reaction at Front Wheel are in Newtons, Vehicle Wheelbase and Horizontal Distance of C.G. from Rear Axle are in Meters, Road Inclination Angle is in Radians, and Friction Coefficient on Front Wheel is dimensionless.
