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 equation:

Where:

• \( \tau \) — Torque (N·m)
• \( F \) — Force applied (N)
• \( r \) — Radius or moment arm (m)

Explanation: The equation calculates the rotational force produced when a force is applied at a distance from a pivot point.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial in mechanical engineering, automotive design, construction, and many other fields where rotational forces need to be measured and controlled.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What's 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 pivot point.

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

Q3: Does the angle of force application matter?
A: Yes, for maximum torque, the force should be applied perpendicular to the moment arm. The effective force is F × sin(θ) where θ is the angle between force and lever arm.

Q4: Where is torque calculation important?
A: Essential in automotive engineering (engine performance), mechanical design (bolts and fasteners), sports (golf swings, baseball bats), and many industrial applications.

Q5: How does gear ratio affect torque?
A: Gear systems can multiply torque. The output torque equals input torque multiplied by the gear ratio (if we neglect friction losses).
