1. What is Grade Resistance?

Grade Resistance is the force, due to gravity, that resists the movement of a vehicle up a slope. It's an important factor in vehicle dynamics and slope stability analysis.

2. How Does the Calculator Work?

The calculator uses the Grade Resistance formula:

Where:

• \( G \) — Grade Resistance (N)
• \( Rg \) — Grade Resistance Factor (N/kg)
• \( PG \) — Percent Grade (%)
• \( W \) — Weight on Wheels (kg)

Explanation: The equation calculates the resistance force that must be overcome when moving a vehicle or equipment up an inclined slope.

3. Importance of Grade Resistance Calculation

Details: Accurate grade resistance calculation is crucial for vehicle design, transportation planning, and determining the power requirements for vehicles operating on inclined surfaces.

4. Using the Calculator

Tips: Enter Grade Resistance Factor in N/kg, Percent Grade in percentage, and Weight on Wheels in kg. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is Grade Resistance Factor?
A: Grade Resistance Factor is a parameter used to account for the effect of the slope on the resistance of soil or other materials to sliding or deformation.

Q2: How is Percent Grade calculated?
A: Percent Grade is calculated as (rise/run) × 100%, representing the steepness of a slope.

Q3: What affects Grade Resistance?
A: Grade Resistance is affected by the slope steepness, vehicle weight, and the specific resistance factor of the terrain.

Q4: Why is this calculation important?
A: This calculation helps determine the additional power required for vehicles to overcome gravitational forces when moving uphill.

Q5: Can this formula be used for all types of vehicles?
A: While the basic principle applies to all vehicles, specific resistance factors may vary based on vehicle type and terrain conditions.
