1. What is Torque by Weight?

Torque, also called moment of force, is the rotational equivalent of linear force. When a weight is applied at a distance from a pivot point, it creates torque. This calculation is fundamental in mechanical engineering and physics.

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

• \( \tau \) — Torque (N·m)
• \( F \) — Force or weight (N)
• \( r \) — Arm length or distance from pivot (m)

Explanation: The torque increases linearly with both the applied force and the distance from the pivot point.

3. Importance of Torque Calculation

Details: Torque calculations are essential for designing mechanical systems, analyzing rotational motion, and ensuring structural integrity in applications like springs, levers, and rotating machinery.

4. Using the Calculator

Tips: Enter the force in newtons (N) and the arm length in meters (m). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for torque calculations?
A: The standard SI unit is newton-meters (N·m). Ensure your force is in newtons and distance in meters for correct results.

Q2: How does torque relate to rotational motion?
A: Torque causes angular acceleration, similar to how force causes linear acceleration (τ = Iα, where I is moment of inertia and α is angular acceleration).

Q3: What's the difference between torque and moment?
A: In physics and engineering, they're often used interchangeably, though moment can sometimes refer to other rotational quantities.

Q4: Can I use this for torsion spring calculations?
A: Yes, this gives the torque applied to the spring. For spring design, you'd also need the spring constant and angular displacement.

Q5: How do I convert pounds to newtons for this calculator?
A: Multiply pounds by 4.44822 to get newtons (1 lbf ≈ 4.44822 N).
