1. What is Torque?

Torque is a measure of the rotational force applied to an object. In linear systems, it represents the tendency of a force to rotate an object about an axis, fulcrum, or pivot.

2. How Does the Calculator Work?

The calculator uses the fundamental torque equation:

Where:

• \( \text{Force} \) — Applied force in Newtons (N)
• \( \text{Distance} \) — Perpendicular distance from the axis of rotation in meters (m)

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

3. Importance of Torque Calculation

Details: Torque calculations are essential in mechanical engineering, physics, and various applications like bolt tightening, engine performance, and structural design.

4. Using the Calculator

Tips: Enter force in Newtons and distance in meters. Both values must be positive numbers. The calculator will compute the torque in Newton-meters (Nm).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between torque and force?
A: Force causes linear acceleration, while torque causes angular acceleration. Torque depends on both the force and where it's applied.

Q2: What are common torque units?
A: The SI unit is Newton-meter (Nm). Other units include pound-feet (lb-ft) and dyne-centimeter (dyn-cm).

Q3: Does the angle of force application matter?
A: Yes, for maximum torque the force should be applied perpendicular to the lever arm. The calculator assumes perpendicular application.

Q4: How is torque used in real-world applications?
A: Torque is crucial in designing engines, gear systems, wrenches, and any rotating machinery.

Q5: What's the relationship between torque and power?
A: Power is torque multiplied by angular velocity. More torque at the same RPM means more power.
