1. What is Torque with Extension?

Torque with extension refers to the rotational force applied when using an extension tool. The extension length affects the effective lever arm, changing the torque output for a given force.

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

• \( F \) — Applied force (newtons)
• \( r \) — Original radius (meters)
• \( \text{extension length} \) — Length of extension tool (meters)

Explanation: The equation accounts for the increased lever arm when using an extension tool by adding the extension length to the original radius.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial for proper fastening, preventing under-tightening (which can lead to loosening) or over-tightening (which can damage components).

4. Using the Calculator

Tips: Enter force in newtons, radius and extension length in meters. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why does extension length affect torque?
A: Extension increases the effective lever arm, resulting in greater torque for the same applied force.

Q2: What are common torque units?
A: Newton-meters (N·m) are standard, but pound-feet (lb·ft) are also commonly used in some industries.

Q3: When would I need this calculation?
A: When using torque wrenches with extensions, cheater bars, or any situation where the effective lever arm differs from the tool's specification.

Q4: Does the extension material matter?
A: The calculation assumes a rigid extension. Flexible extensions may require additional considerations for accurate torque measurement.

Q5: How precise should my measurements be?
A: For critical applications, measure force, radius and extension length as precisely as possible to ensure accurate torque calculation.
