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 force and the perpendicular distance from the axis of rotation to the line of action of the force.

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

• \( T \) — Torque (Newton-meters, Nm)
• \( F \) — Force applied (Newtons, N)
• \( r \) — Radius or distance from axis (meters, m)

Explanation: The formula calculates the rotational force generated when a linear force is applied at a certain distance from a pivot point.

3. Importance of Torque Calculation

Details: Torque calculation is essential in mechanical engineering, automotive design, robotics, and many other fields where rotational motion is involved. It helps determine the force needed to rotate objects and is crucial for designing mechanical systems.

4. Using the Calculator

Tips: Enter force in Newtons (N) and radius in meters (m). Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What units are used for torque calculation?
A: Torque is typically measured in Newton-meters (Nm) in the SI system. Other units include pound-feet (lb-ft) and kilogram-force meters (kgf·m).

Q2: How does direction affect torque?
A: Torque is a vector quantity with direction perpendicular to the plane of rotation. The right-hand rule is used to determine the direction of the torque vector.

Q3: What's the difference between torque and moment?
A: While often used interchangeably, torque specifically refers to rotational force about an axis, while moment can refer to rotational tendency about a point or axis.

Q4: Can torque be negative?
A: Yes, torque can be negative when the rotational force acts in the opposite direction to what is defined as positive rotation.

Q5: How is torque measured in real-world applications?
A: Torque is measured using torque wrenches, torque sensors, or dynamometers in various engineering and automotive applications.
