1. What is Total Resistance on Vehicle?

Total Resistance on Vehicle is defined as the sum of all the resistances that oppose the forward motion of the vehicle at any given time. It includes aerodynamic resistance, rolling resistance, and gradient resistance.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( R_t \) — Total Resistance on Vehicle (N)
• \( F'_a \) — Aerodynamic Resistance of Vehicle (N)
• \( F_r \) — Rolling Resistance at Wheel (N)
• \( F_g \) — Gradient Resistance (N)

Explanation: The equation calculates the sum of all resistive forces acting against the vehicle's motion, including air resistance, tire rolling resistance, and resistance due to road gradient.

3. Importance of Total Resistance Calculation

Details: Calculating total resistance is crucial for vehicle performance analysis, fuel efficiency estimation, and determining the power requirements for maintaining a given speed or overcoming inclines.

4. Using the Calculator

Tips: Enter all resistance values in Newtons (N). All values must be non-negative numbers. The calculator will sum the three resistance components to give you the total resistance.

5. Frequently Asked Questions (FAQ)

Q1: What is aerodynamic resistance?
A: Aerodynamic Resistance of Vehicle is the resistive force offered by the air particles when the vehicle is moving at higher speeds.

Q2: What is rolling resistance?
A: Rolling Resistance at Wheel is the force that resists the motion of a wheel rolling on a surface or ground.

Q3: What is gradient resistance?
A: Gradient Resistance is the resistance due to the inclination of the road surface.

Q4: How do these resistances affect vehicle performance?
A: Higher total resistance requires more engine power to maintain speed, reducing fuel efficiency and overall performance.

Q5: Can this calculator be used for all vehicle types?
A: Yes, the basic principle applies to all vehicles, though the specific resistance values will vary depending on vehicle design, weight, and other factors.
