1. What is Torque?

Torque is a measure of the rotational force applied to an object. It represents how much force is acting on an object to cause it to rotate about an axis. In physics, torque is calculated as the product of force and the perpendicular distance from the axis of rotation.

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

• \( \tau \) — Torque (Newton-meters, N·m)
• \( m \) — Mass (kilograms, kg)
• \( a \) — Acceleration (meters per second squared, m/s²)
• \( r \) — Radius (meters, m)

Explanation: This equation calculates the torque required to accelerate a mass at a certain rate at a specific distance from the axis of rotation.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial for designing mechanical systems, determining motor requirements, analyzing rotational motion, and ensuring proper functioning of various machines and equipment.

4. Using the Calculator

Tips: Enter mass in kilograms, acceleration in meters per second squared, and radius in meters. All values must be positive numbers.

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 is essentially the rotational equivalent of force.

Q2: How does radius affect torque?
A: Torque increases linearly with radius. A longer lever arm (greater radius) produces more torque for the same amount of force.

Q3: What are common units for torque?
A: Newton-meters (N·m) in the SI system, and pound-feet (lb·ft) in the imperial system.

Q4: Where is torque calculation important?
A: Essential in automotive engineering (engine performance), robotics, industrial machinery, and any application involving rotational motion.

Q5: How does mass distribution affect torque?
A: For extended objects, the moment of inertia (which depends on mass distribution) affects rotational acceleration, not just the total mass.
