1. What is Torque?

Torque is a measure of the force that can cause an object to rotate about an axis. It is a vector quantity, meaning it has both magnitude and direction. Torque is calculated as the product of the force applied and the lever arm length.

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

• \( T \) — Torque (Newton-meters, Nm)
• \( F \) — Force applied (Newtons, N)
• \( l \) — Lever arm length (meters, m)

Explanation: The equation shows that torque is directly proportional to both the applied force and the length of the lever arm.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial in mechanical engineering, physics, and various applications including automotive systems, machinery design, and construction.

4. Using the Calculator

Tips: Enter force in Newtons and lever arm length in meters. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What units are used for torque?
A: Torque is typically measured in Newton-meters (Nm) in the SI system, or foot-pounds (ft-lb) in the imperial system.

Q2: How does lever length affect torque?
A: Torque increases proportionally with lever length. A longer lever arm produces more torque for the same amount of force.

Q3: What's the difference between torque and force?
A: Force causes linear acceleration, while torque causes rotational acceleration. Torque depends on both the magnitude of force and where it's applied.

Q4: Can torque be negative?
A: Yes, torque can be negative when it acts in the opposite direction of what is considered positive rotation.

Q5: What are some real-world applications of torque?
A: Torque is important in many applications including tightening bolts, engine performance, gear systems, and any rotating machinery.
