1. What is Torque?

Torque is a measure of the force that can cause an object to rotate about an axis. It is the rotational equivalent of linear force and is calculated as the product of the force (weight) and the distance (radius) from the pivot point.

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

• \( \tau \) — Torque (Newton-meters, Nm)
• \( Weight \) — Force applied (Newtons, N)
• \( r \) — Distance from pivot point (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 automotive systems (engine torque), construction equipment, and even simple tools like wrenches.

4. Using the Calculator

Tips: Enter weight in Newtons (N) and radius in meters (m). Both values must be positive numbers. For pounds and feet, convert to metric units first.

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: How do I convert pounds to Newtons?
A: Multiply pounds by 4.44822 to get Newtons (1 lb ≈ 4.44822 N).

Q3: What if my radius is in centimeters?
A: Convert to meters by dividing by 100 (1 cm = 0.01 m) before entering the value.

Q4: Can torque be negative?
A: Yes, torque can be negative indicating direction of rotation (clockwise vs counterclockwise), but this calculator shows magnitude only.

Q5: What are common torque values in everyday life?
A: A person using a wrench might apply 10-50 Nm, car engines produce 100-500 Nm, while precision instruments might need <1 Nm.
