1. What is Torque?

Torque is a measure of the force that can cause an object to rotate about an axis. It is a vector quantity, meaning it has both magnitude and direction. Torque is calculated as the product of the force applied and the distance from the pivot point.

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

• \( \tau \) — Torque (N·m)
• \( r \) — Radius or moment arm (m)
• \( F \) — Force applied perpendicular to the radius (N)

Explanation: The torque increases with both the magnitude of the force and the distance from the pivot point at which the force is applied.

3. Importance of Torque Calculation

Details: Torque calculation is essential in mechanical engineering, automotive design, physics, and many practical applications involving rotational motion. It helps determine the effectiveness of a force in producing rotation.

4. Using the Calculator

Tips: Enter the radius in meters and force in newtons. Both values must be positive numbers. The calculator will compute the torque in newton-meters (N·m).

5. Frequently Asked Questions (FAQ)

Q1: 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 where it's applied.

Q2: Why is the direction of force important for torque?
A: Only the component of force perpendicular to the moment arm contributes to torque. Force applied parallel to the moment arm produces no torque.

Q3: What are common units for torque?
A: Newton-meters (N·m) in the SI system, and pound-feet (lb·ft) or pound-inches (lb·in) in the imperial system.

Q4: How does torque relate to power in engines?
A: Power = Torque × Angular velocity. Engine torque represents the rotational force available at the crankshaft.

Q5: Can torque be negative?
A: Yes, torque can be negative when it acts in the opposite direction to what is defined as positive, typically clockwise vs. counterclockwise rotation.
