1. What is Torque?

Torque is a measure of the rotational force applied to an object. It represents how much force is acting on an object to cause it to rotate about 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 formula:

Where:

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

Explanation: The torque is calculated by multiplying the applied force by the perpendicular distance from the axis of rotation to the line of action of the force.

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 and machinery.

4. Using the Calculator

Tips: Enter the force value in Newtons and the radius value in meters. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What units are used for torque measurement?
A: Torque is typically measured in Newton-meters (Nm) in the SI system, or pound-feet (lb-ft) in the imperial system.

Q2: How does the direction of force affect torque?
A: Only the component of force perpendicular to the moment arm contributes to torque. The direction of application significantly affects the resulting torque value.

Q3: 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 axis of rotation.

Q4: Can torque be negative?
A: Yes, torque can be negative when the force tends to cause rotation in the clockwise direction (depending on the coordinate system convention used).

Q5: What are some real-world applications of torque?
A: Torque is crucial in automotive engineering (engine performance, wheel rotation), mechanical design (bolts, fasteners), sports (golf swings, baseball bats), and many other applications involving rotational motion.
