1. What is Torque?

Torque is a measure of the rotational force applied to an object. It's the product of the force applied, the distance from the pivot point (lever arm), and the sine of the angle between the force vector and the lever arm.

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

• \( \tau \) — Torque (N·m)
• \( F \) — Force applied (newtons)
• \( r \) — Distance from pivot (meters)
• \( \theta \) — Angle between force and lever arm (degrees)

Explanation: The equation shows that torque depends on both the magnitude of the force and how effectively it's applied (determined by the angle).

3. Importance of Torque Calculation

Details: Torque calculations are essential in mechanical engineering, vehicle design, construction, and many other fields where rotational forces are involved.

4. Using the Calculator

Tips: Enter force in newtons, distance in meters, and angle in degrees (0-180). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What angle gives maximum torque?
A: Maximum torque occurs at 90 degrees, when the force is perpendicular to the lever arm.

Q2: What happens at 0 or 180 degrees?
A: Torque is zero because the force is directly toward or away from the pivot point.

Q3: How does distance affect torque?
A: Torque increases linearly with distance - doubling the lever arm doubles the torque.

Q4: What are common torque units?
A: Newton-meters (N·m) are standard, but pound-feet (lb·ft) are also commonly used.

Q5: How is torque different from force?
A: Force causes linear acceleration, while torque causes angular acceleration (rotation).
