1. What is Torque?

Torque is a measure of the rotational force applied to an object. In mechanical systems, torque determines the rotational effect of a force applied at a distance from the pivot point.

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

• \( Torque \) — Rotational force (Nm)
• \( Force \) — Applied force (N)
• \( Radius \) — Distance from pivot point (m)

Explanation: The formula calculates the rotational effect produced when a force is applied perpendicular to a lever arm at a certain distance from the axis of rotation.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial for designing mechanical systems, determining gear requirements, calculating power transmission, and ensuring proper functioning of rotating machinery.

4. Using the Calculator

Tips: Enter force in Newtons (N) and radius in meters (m). Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What units are used for torque calculation?
A: Torque is typically measured in Newton-meters (Nm) in the SI system, where force is in Newtons and radius is in meters.

Q2: How does torque relate to power?
A: Power = Torque × Angular Velocity. Torque represents the rotational force, while power represents the rate at which work is done.

Q3: What factors affect torque in gear systems?
A: Gear ratio, input force, gear radius, friction, and efficiency all affect the torque output in gear systems.

Q4: Why is torque important in mechanical engineering?
A: Torque is essential for designing motors, engines, gearboxes, and any rotating machinery to ensure they can handle required loads and operate efficiently.

Q5: Can torque be negative?
A: Yes, torque can be negative when it acts in the opposite direction of the defined positive rotation, indicating clockwise vs counterclockwise rotation.
