1. What is Grade Resistance Factor?

Grade Resistance Factor is a parameter used to account for the effect of the slope (or grade) of the terrain on the resistance of soil or other materials to sliding or deformation.

2. How Does the Calculator Work?

The calculator uses the Grade Resistance Factor formula:

Where:

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

Explanation: The equation calculates the resistance factor by dividing the grade resistance by the product of percent grade and weight on wheels.

3. Importance of Grade Resistance Factor

Details: Grade Resistance Factor is crucial for understanding how slope conditions affect vehicle movement and material resistance, particularly in construction, mining, and transportation applications.

4. Using the Calculator

Tips: Enter grade resistance in Newtons, percent grade as a percentage value, and weight on wheels in kilograms. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is Grade Resistance?
A: Grade Resistance is the force, due to gravity, that resists the movement of a vehicle up a slope.

Q2: How is Percent Grade measured?
A: Percent Grade is a measure of the steepness or incline of a slope, expressed as a percentage of vertical rise over horizontal run.

Q3: What does Weight on Wheels represent?
A: Weight on Wheels is the weight of equipment that is resting on its wheels, representing the load distribution.

Q4: What are typical values for Grade Resistance Factor?
A: Values vary depending on terrain conditions, vehicle type, and load distribution, but typically range from 0.01 to 0.5 N/kg.

Q5: How is this factor used in practical applications?
A: It's used to calculate the additional power required for vehicles to overcome slope resistance and to design appropriate braking systems for downhill movement.
