1. What is Torque?

Torque is a measure of the turning force on an object such as a bolt or a flywheel. In mechanical systems, torque is the rotational equivalent of linear force. The unit of torque is the pound-foot (lb-ft) in the imperial system.

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

• \( Force \) — Applied force in pounds (lb)
• \( Distance \) — Distance from pivot point in feet (ft)

Explanation: The torque increases with either greater force or greater distance from the pivot point.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial for proper tightening of bolts, mechanical design, and understanding rotational systems. Too little torque might not secure components properly, while too much torque can damage parts.

4. Using the Calculator

Tips: Enter force in pounds and distance in feet. Both values must be positive numbers. The calculator will compute the torque in pound-feet (lb-ft).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between lb-ft and ft-lb?
A: They are the same unit - pound-feet (lb-ft) is the same as foot-pounds (ft-lb), both representing torque.

Q2: How do I convert lb-ft to Nm?
A: Multiply lb-ft by 1.35582 to get Newton-meters (Nm).

Q3: Why is distance important in torque?
A: Torque depends on both force and the lever arm length. A longer wrench gives more torque for the same force.

Q4: What's a typical torque value for car lug nuts?
A: Typically 80-100 lb-ft for passenger cars, but always check your vehicle's specifications.

Q5: Can I use this for angular torque calculations?
A: This calculates static torque. For angular torque with rotation, additional factors like angular acceleration must be considered.
