1. What is Torque?

Torque is a measure of the rotational force applied to an object. It represents the tendency of a force to rotate an object about an axis, fulcrum, or pivot. Torque is a vector quantity with both magnitude and direction.

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

• \( T \) — Torque (Newton-meters, Nm)
• \( F \) — Force applied (Newtons, N)
• \( d \) — Distance from pivot point (meters, m)

Explanation: The torque produced is directly proportional to both the applied force and the distance from the pivot point at which the force is applied.

3. Importance of Torque Calculation

Details: Accurate torque calculation is essential in mechanical engineering, automotive design, structural analysis, and various applications involving rotational motion and leverage systems.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What are the SI units for torque?
A: The SI unit for torque is Newton-meter (Nm). Other common units include pound-feet (lb-ft) and kilogram-meter (kg-m).

Q2: How does distance affect torque?
A: Torque increases linearly with distance. Doubling the distance from the pivot point while maintaining the same force will double the torque.

Q3: What's the difference between torque and force?
A: Force causes linear acceleration, while torque causes rotational acceleration. Torque depends on both the magnitude of force and the distance from the pivot.

Q4: Can torque be negative?
A: Yes, torque can be negative when it acts in the opposite direction of the defined positive rotation. The sign indicates the direction of rotation.

Q5: How is torque used in real-world applications?
A: Torque is crucial in automotive engines (engine torque), mechanical tools (wrenches, screwdrivers), structural engineering (beam loading), and many mechanical systems involving rotation.
