1. What is Torque?

Torque is a measure of the rotational force applied to an object. It represents the tendency of a force to rotate an object about an axis, fulcrum, or pivot. Torque is measured in newton-meters (Nm) in the SI system.

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

• \( T \) — Torque (Nm)
• \( F \) — Force applied (N)
• \( r \) — Distance from axis (m)
• \( \theta \) — Angle between force vector and lever arm (degrees)

Explanation: The equation calculates the rotational force based on the magnitude of force, distance from the pivot point, and the angle at which the force is applied.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial in mechanical engineering, automotive design, construction, and various industrial applications where rotational forces need to be precisely measured and controlled.

4. Using the Calculator

Tips: Enter force in newtons (N), radius in meters (m), and angle in degrees. All values must be valid (force > 0, radius > 0, angle between 0-90 degrees).

5. Frequently Asked Questions (FAQ)

Q1: What is 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 the distance from the pivot point.

Q2: Why is the angle important in torque calculation?
A: The angle determines the effective component of the force that produces rotation. Maximum torque occurs when the force is perpendicular to the lever arm (θ = 90°).

Q3: What are typical torque values in everyday applications?
A: Torque values vary widely - from small electronic components requiring fractions of Nm to large industrial machinery requiring thousands of Nm.

Q4: How does torque relate to power in engines?
A: Power = Torque × Angular Velocity. Higher torque at lower RPMs generally means better acceleration and pulling power.

Q5: Can torque be negative?
A: Yes, torque can be negative when it acts in the opposite direction of the defined positive rotation, indicating clockwise vs counterclockwise rotation.
