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 calculated as the product of the force applied and the perpendicular distance from the axis of rotation to the line of action of the force.

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

• \( \tau \) — Torque (N·m or lb·ft)
• \( F \) — Force applied (Newtons or pounds)
• \( d \) — Perpendicular distance from axis (meters or feet)

Explanation: The equation shows that torque increases with either greater force or greater distance from the rotation axis. Units must be consistent (N with m, lb with ft).

3. Importance of Torque Calculation

Details: Torque calculation is essential in mechanical engineering, automotive design, construction, and many industrial applications. It helps determine the rotational force needed for bolts, engines, motors, and various mechanical systems to operate properly and safely.

4. Using the Calculator

Tips: Enter the force value and select appropriate units (N or lb). Enter the distance from the rotation axis and select appropriate units (m or ft). Ensure consistent unit selection for accurate results.

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 the distance from the pivot point.

Q2: Can I mix different units (e.g., N with ft)?
A: While the calculator will compute the result, mixing incompatible units may lead to incorrect interpretations. It's recommended to use consistent unit pairs (N with m, lb with ft).

Q3: What are typical torque values in everyday applications?
A: Car wheel nuts: 80-120 N·m, bicycle pedals: 30-40 N·m, door handles: 2-5 N·m. Values vary significantly based on application.

Q4: How does torque relate to power?
A: Power = Torque × Angular Velocity. Higher torque at the same RPM means more power, which is why diesel engines often feel more powerful at lower RPMs.

Q5: Why is perpendicular distance important?
A: Only the component of distance perpendicular to the force direction contributes to torque. Applying force at an angle reduces effective torque.
