1. What is Torque?

Torque is a measure of the rotational force applied to an object. It is calculated as the product of the force applied perpendicular to the radius of rotation.

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

• \( \tau \) — Torque (Nm)
• \( F \) — Force applied (N)
• \( r \) — Radius or moment arm (m)

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

3. Importance of Torque Calculation

Details: Torque calculations are essential in mechanical engineering, automotive design, and any application involving rotational systems.

4. Using the Calculator

Tips: Enter force in newtons (N) and radius in meters (m). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are common units for torque?
A: The SI unit is Newton-meters (Nm). Other units include pound-feet (lb-ft) and dyne-centimeters (dyn-cm).

Q2: How does torque differ from power?
A: Torque measures rotational force, while power measures how fast work is done (torque × angular velocity).

Q3: What's the right-hand rule in torque?
A: It determines torque direction - point fingers in rotation direction, thumb points along torque vector.

Q4: How does gear ratio affect torque?
A: Gear reduction increases torque while decreasing speed proportionally.

Q5: What's static vs dynamic torque?
A: Static torque doesn't produce rotation, dynamic torque causes angular acceleration.
