1. What is Torque?

Torque is a measure of the rotational force applied to an object. It describes how much force is acting on an object to cause it to rotate around an axis. Torque is a crucial concept in physics and engineering, particularly in mechanics and rotational dynamics.

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

• \( T \) — Torque (Newton-meters)
• \( F \) — Force applied (Newtons)
• \( r \) — Distance from axis (meters)
• \( \theta \) — Angle between force vector and lever arm (degrees)

Explanation: The equation calculates the rotational force by multiplying the applied force by the distance from the pivot point and the sine of the angle between the force vector and the lever arm.

3. Importance of Torque Calculation

Details: Accurate torque calculation is essential for designing mechanical systems, analyzing rotational motion, determining the effectiveness of forces in causing rotation, and ensuring proper functioning of various mechanical components.

4. Using the Calculator

Tips: Enter force in Newtons, radius in meters, and angle in degrees (0-90). All values must be valid positive numbers within the specified ranges.

5. Frequently Asked Questions (FAQ)

Q1: What is the unit of torque?
A: Torque is measured in Newton-meters (Nm) in the SI system.

Q2: Why is the angle important in torque calculation?
A: The angle determines how much of the applied force contributes to rotation. Maximum torque occurs when the force is perpendicular to the lever arm (θ = 90°).

Q3: What happens when the angle is 0 degrees?
A: When the force is parallel to the lever arm (θ = 0°), sin(0) = 0, so no torque is produced as the force doesn't cause rotation.

Q4: 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.

Q5: How is torque different from force?
A: Force causes linear acceleration, while torque causes rotational acceleration. Torque depends on both the magnitude of force and its point of application relative to the axis of rotation.
