1. What is Torque?

Torque is a measure of the rotational force applied to an object. It is calculated as the product of the force applied perpendicular to the rotation axis and the distance from the axis (radius).

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

• \( \tau \) — Torque (Nm)
• \( F \) — Force applied (N)
• \( r \) — Distance from axis (m)

Explanation: The equation shows that torque increases with either greater force or greater distance from the rotation axis.

3. Importance of Torque Calculation

Details: Torque calculations are essential in mechanical engineering, automotive design, and any application involving rotational systems. Proper torque ensures components function correctly without failing.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What units should I use?
A: The calculator uses standard SI units - newtons (N) for force and meters (m) for radius, resulting in newton-meters (Nm) for torque.

Q2: Does the force direction matter?
A: Yes, this calculation assumes the force is applied perpendicular to the radius. For angled forces, trigonometric adjustments are needed.

Q3: What's a typical torque range?
A: Torque values vary widely from tiny (watch mechanisms) to enormous (ship engines). Always consider your specific application.

Q4: How does this relate to power?
A: Power equals torque multiplied by angular velocity. Both are important in rotational systems.

Q5: What if my force isn't perpendicular?
A: You would need to multiply by the sine of the angle between the force vector and radius vector.
