1. What is Torque?

Definition: Torque is a measure of the rotational force applied to an object.

Purpose: It's crucial in mechanical systems, engineering, and physics to understand rotational effects of forces.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: Torque increases with either greater force or greater distance from the pivot point.

3. Importance of Torque Calculation

Details: Proper torque calculation is essential for designing mechanical systems, tightening bolts, and understanding rotational motion.

4. Using the Calculator

Tips: Enter the force in Newtons and the perpendicular distance from the pivot point in meters. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between torque and force?
A: Force causes linear acceleration, while torque causes angular acceleration (rotation).

Q2: Why does distance matter in torque?
A: The same force applied farther from the pivot creates more rotational effect (greater torque).

Q3: What are common torque units?
A: Newton-meters (Nm) in SI units, or foot-pounds (ft-lb) in imperial units.

Q4: How is torque used in real life?
A: In wrenches, car engines, bicycle pedals, and any rotating system where force is applied.

Q5: Does the angle of force affect torque?
A: Yes, only the perpendicular component of force creates torque. For maximum torque, apply force at 90° to the lever arm.
