1. What is the Weight of Vehicle given Kinetic Energy of Vehicle at Design Speed Formula?

The formula calculates the total weight of a vehicle based on its kinetic energy at design speed, using maximum frictional force, braking distance, and velocity. It's essential for vehicle design and safety analysis.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ W = \frac{2 \times [g] \times F \times l}{v_{vehicle}^2} \]

Where:

\( W \) — Total Weight of Vehicle (Kilogram)
\( [g] \) — Gravitational acceleration on Earth (9.80665 m/s²)
\( F \) — Maximum Frictional Force (Newton)
\( l \) — Braking Distance (Meter)
\( v_{vehicle} \) — Velocity (Meter per Second)

Explanation: This formula derives the vehicle's total weight from the relationship between kinetic energy, frictional force, and braking distance.

3. Importance of Total Weight Calculation

Details: Accurate weight calculation is crucial for vehicle safety assessment, braking system design, and determining optimal performance characteristics.

4. Using the Calculator

Tips: Enter maximum frictional force in Newton, braking distance in meters, and velocity in meters per second. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is gravitational acceleration included in the formula?
A: Gravitational acceleration is used to relate the frictional force (which depends on weight) to the vehicle's mass and subsequent kinetic energy.

Q2: What constitutes a typical maximum frictional force?
A: This varies based on road conditions, tire quality, and vehicle type, but is typically derived from the coefficient of friction multiplied by the normal force.

Q3: How does velocity affect the calculated weight?
A: Since velocity is squared in the denominator, higher speeds result in a lower calculated weight for the same braking distance and frictional force.

Q4: Are there limitations to this calculation?
A: This assumes ideal conditions with constant deceleration and doesn't account for factors like air resistance, road incline, or brake system efficiency.

Q5: Can this formula be used for all vehicle types?
A: While the fundamental physics applies to all vehicles, specific adjustments may be needed for unusual vehicle designs or special conditions.
