1. What is a Torque Calculator with Extensions?

Definition: This calculator computes torque by multiplying force by the length of the lever arm or extension.

Purpose: It helps mechanics, engineers, and DIY enthusiasts determine the torque applied when using tools with extensions.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — Torque (pound-feet)
• \( F \) — Force applied (pounds)
• \( L \) — Lever arm length (feet)

Explanation: The force applied perpendicular to the lever arm multiplied by the length of the lever arm equals the torque.

3. Importance of Torque Calculation

Details: Proper torque calculation ensures correct fastener tension, prevents damage to components, and maintains safety in mechanical systems.

4. Using the Calculator

Tips: Enter the force in pounds and the lever arm length in feet. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What happens if I use an extension on my torque wrench?
A: The actual torque applied changes because the extension increases the effective lever arm length.

Q2: How do I measure lever arm length?
A: Measure from the center of rotation to the point where force is applied.

Q3: Does the angle of force application matter?
A: Yes, this calculator assumes perpendicular force. For angled forces, multiply by the sine of the angle.

Q4: What units should I use?
A: This calculator uses pounds and feet, but you can convert other units to these before input.

Q5: How accurate is this calculation?
A: It provides theoretical torque. Actual torque may vary due to friction, tool accuracy, and other factors.
