1. What is the Torque Equation?

The torque equation (T = F × r) calculates the rotational force or moment created when a linear force is applied at a distance from a pivot point. It is a fundamental concept in physics and engineering mechanics.

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

• \( T \) — Torque (Nm)
• \( F \) — Force (N)
• \( r \) — Radius or moment arm (m)

Explanation: The equation shows that torque is directly proportional to both the applied force and the distance from the pivot point at which the force is applied.

3. Importance of Torque Calculation

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

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 is the difference between torque and force?
A: Force is a linear push or pull, while torque is a rotational force that causes angular acceleration. Torque depends on both the magnitude of force and the distance from the pivot point.

Q2: What are common units for torque?
A: The SI unit is newton-meter (Nm). Other common units include pound-foot (lb-ft) and pound-inch (lb-in).

Q3: How does the direction of force affect torque?
A: Torque is maximized when force is applied perpendicular to the radius vector. The angle between force and radius affects the effective torque.

Q4: What is the right-hand rule for torque?
A: The right-hand rule determines the direction of torque: point fingers in direction of radius, curl toward force direction, and thumb points in torque direction.

Q5: Where is torque calculation used in real life?
A: Torque calculations are essential in automotive engineering (engine performance), mechanical design (bolts and fasteners), sports (golf swings), and many other applications involving rotational motion.
