1. What is Torque?

Torque is a measure of the rotational force applied to an object. It's calculated as the product of force and the distance from the pivot point (radius). In this case, we calculate torque from a mass acting under gravity at a certain radius.

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

• \( \tau \) — Torque (Newton-meters)
• \( m \) — Mass (kilograms)
• \( g \) — Acceleration due to gravity (9.8 m/s²)
• \( r \) — Radius or moment arm (meters)

Explanation: The equation calculates the rotational force produced by a given mass at a specified distance from the pivot point.

3. Importance of Torque Calculation

Details: Torque calculations are essential in mechanical engineering, physics, and various applications like motor sizing, gear design, and structural analysis.

4. Using the Calculator

Tips: Enter mass in kilograms and radius in meters. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are typical torque units?
A: The SI unit is Newton-meters (Nm). Other common units include pound-feet (lb-ft) and kilogram-meters (kg-m).

Q2: How does radius affect torque?
A: Torque increases linearly with radius. Doubling the radius doubles the torque for the same force.

Q3: Why use 9.8 m/s² for gravity?
A: This is the standard acceleration due to gravity at Earth's surface. It varies slightly by location but 9.8 is used for most calculations.

Q4: Can I use this for angular torque calculations?
A: This calculates static torque. For angular acceleration, you would need to consider moment of inertia and angular acceleration.

Q5: How is this different from work or energy?
A: While both use similar units (Nm), torque is a rotational force while work/energy is force applied over a distance.
