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 moment arm (meters, m)

Explanation: The formula calculates the rotational force applied at a distance from the pivot point. The longer the moment arm or the greater the applied force, the larger the resulting torque.

3. Importance of Torque Calculation

Details: Torque calculation is essential in mechanical engineering, automotive design, robotics, and many other fields. It helps determine the rotational force needed for various applications, from tightening bolts to designing engine components.

4. Using the Calculator

Tips: Enter force in Newtons and radius in meters. Both values must be positive numbers. The calculator will compute the torque in Newton-meters.

5. Frequently Asked Questions (FAQ)

Q1: What units are used for torque calculation?
A: The standard SI unit for torque is Newton-meter (Nm). Other units include pound-feet (lb-ft) and kilogram-force meter (kgf·m).

Q2: How does direction affect torque?
A: Torque is a vector quantity with direction. The direction is perpendicular to the plane containing the force vector and the moment arm, following the right-hand rule.

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

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