1. What is Torque?

Torque is a measure of the rotational force applied to an object. It's calculated as the product of force and the perpendicular distance from the axis of rotation to the line of action of the force.

2. How Does the Calculator Work?

The calculator uses the fundamental torque equation:

Where:

• \( T \) — Torque (Newton-meters, Nm)
• \( F \) — Force applied (Newtons, N)
• \( r \) — Radius or moment arm (meters, m)

Explanation: The equation shows that torque increases with either greater force or longer moment arm.

3. Importance of Torque Calculation

Details: Torque calculations are essential in mechanical engineering, automotive design, robotics, and many other fields where rotational motion is involved. Proper torque specification ensures systems operate efficiently without failure.

4. Using the Calculator

Tips: Enter force in Newtons and radius in meters. Both values must be positive numbers. The calculator will compute the resulting torque in Newton-meters (Nm).

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 (torque × angular velocity).

Q2: How does gear ratio affect torque?
A: Gear reduction increases output torque while decreasing speed, maintaining power (minus efficiency losses).

Q3: What are typical torque values for electric motors?
A: Small motors might produce 0.1-1 Nm, while industrial motors can produce hundreds of Nm.

Q4: How do you measure torque in practice?
A: Torque wrenches, dynamometers, or strain gauges can be used depending on the application.

Q5: Why is torque important in vehicle performance?
A: Torque determines a vehicle's acceleration capability, especially at low speeds.
