1. What is Torque?

Torque is a measure of the rotational force applied to an object. In this context, it's calculated from weight (mass × gravity) acting at a distance from a pivot point.

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

• \( \tau \) — Torque (Newton-meters)
• \( m \) — Mass (kilograms)
• \( g \) — Gravitational acceleration (9.8 m/s² on Earth)
• \( r \) — Radius or distance from pivot (meters)

Explanation: The equation shows that torque increases with greater mass, stronger gravity, or longer moment arm.

3. Importance of Torque Calculation

Details: Torque calculations are essential in mechanical engineering, physics, and any application involving rotational forces like engines, levers, and bolts.

4. Using the Calculator

Tips: Enter mass in kilograms, radius in meters, and gravity (default is Earth's gravity 9.8 m/s²). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use?
A: For consistent results, use kilograms for mass, meters for radius, and m/s² for gravity. The result will be in Newton-meters (Nm).

Q2: Can I calculate torque in different gravity?
A: Yes, change the gravity value (e.g., 1.62 m/s² for the Moon or 3.71 m/s² for Mars).

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

Q4: How does radius affect torque?
A: Torque is directly proportional to radius - doubling the radius doubles the torque for the same force.

Q5: Is this the same as moment of force?
A: Yes, torque is also called the moment of force or rotational force.
