1. What Is Wheel Torque?

Wheel torque is the rotational force applied to a wheel, calculated as the product of the force applied perpendicular to the radius and the distance from the center of rotation. It's a crucial measurement in automotive engineering and mechanical systems.

2. How Does The Calculator Work?

The calculator uses the torque formula:

Where:

• \( T \) — Torque (Newton-meters, Nm)
• \( F \) — Force applied perpendicular to the radius (Newtons, N)
• \( r \) — Radius or distance from center (meters, m)

Explanation: This formula calculates the rotational force generated when a linear force is applied at a certain distance from the center of rotation.

3. Importance Of Torque Calculation

Details: Accurate torque calculation is essential for designing mechanical systems, determining vehicle performance, optimizing gear ratios, and ensuring proper force transmission in rotating machinery.

4. Using The Calculator

Tips: Enter the force value in Newtons and the radius in meters. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between torque and power?
A: Torque is a rotational force, while power is the rate at which work is done. Power equals torque multiplied by rotational speed.

Q2: Why is wheel torque important in vehicles?
A: Wheel torque determines a vehicle's acceleration capability, towing capacity, and hill-climbing ability. It's directly related to the force that propels the vehicle forward.

Q3: How does gear ratio affect wheel torque?
A: Gear ratios multiply engine torque. Lower gears provide higher torque multiplication at the wheels, improving acceleration and climbing ability.

Q4: What factors can affect actual wheel torque?
A: Actual wheel torque can be affected by traction limits, drivetrain efficiency, tire inflation, and surface conditions.

Q5: How is wheel torque related to vehicle performance?
A: Higher wheel torque generally means better acceleration and pulling power, but it must be balanced with appropriate gearing and traction control systems.
