1. What is the Weight On Wheels Formula?

The Weight On Wheels formula calculates the weight resting on equipment wheels based on rolling resistance, rolling resistance factor, tire penetration factor, and tire penetration depth. This calculation is essential for understanding vehicle dynamics and performance.

2. How Does the Calculator Work?

The calculator uses the Weight On Wheels formula:

\[ W = \frac{R}{R_f + R_p \times p} \]

Where:

\( W \) — Weight on Wheels (Kilogram)
\( R \) — Rolling Resistance (Newton)
\( R_f \) — Rolling Resistance Factor (Newton per Kilogram)
\( R_p \) — Tire Penetration Factor (Radian per Square Second)
\( p \) — Tire Penetration (Meter)

Explanation: The formula accounts for the relationship between rolling resistance, tire characteristics, and the resulting weight distribution on wheels.

3. Importance of Weight On Wheels Calculation

Details: Accurate weight on wheels calculation is crucial for vehicle design, load distribution analysis, tire selection, and optimizing vehicle performance and safety.

4. Using the Calculator

Tips: Enter rolling resistance in Newton, rolling resistance factor in Newton per Kilogram, tire penetration factor in Radian per Square Second, and tire penetration in Meter. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is rolling resistance?
A: Rolling resistance is the force that resists the motion when a body rolls on a surface, primarily due to deformation of the tire and surface.

Q2: How does tire penetration affect weight on wheels?
A: Greater tire penetration increases the resistance factor, which affects the weight distribution calculation on the wheels.

Q3: What are typical values for rolling resistance factor?
A: Rolling resistance factor varies by tire type and surface, typically ranging from 0.01 to 0.05 Newton per Kilogram for most vehicle tires.

Q4: When is this calculation most important?
A: This calculation is particularly important for heavy equipment, aircraft landing gear, and vehicles operating on soft or uneven surfaces.

Q5: Are there limitations to this formula?
A: The formula provides an estimation and may need adjustment for extreme conditions, unusual tire designs, or non-standard surface materials.
