1. What is Torque?

Torque is a measure of the rotational force applied to an object. It's calculated as the product of the force applied perpendicular to the lever arm and the distance from the pivot point to the point where the force is applied.

2. How Does the Calculator Work?

The calculator uses the torque equation:

\[ \tau = F \times d \]

Where:

Explanation: The equation shows that torque increases with either greater force or longer lever arm distance.

3. Importance of Torque Calculation

Details: Torque calculations are essential in mechanical engineering, physics, and everyday tools like wrenches. Proper torque ensures efficient force application and prevents mechanical failures.

4. Using the Calculator

Tips: Enter force in newtons (N) and distance in meters (m). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between torque and force?
A: Force is a push or pull, while torque is the rotational equivalent that causes angular acceleration.

Q2: Why does distance affect torque?
A: Longer lever arms create greater rotational force because the same force is applied over a greater distance.

Q3: What are common torque units?
A: Newton-meters (N·m) are standard, but pound-feet (lb·ft) are also used, especially in automotive applications.

Q4: How does angle affect torque?
A: Maximum torque occurs when force is perpendicular to the lever arm. The effective torque is reduced by the sine of the angle between force and lever.

Q5: Where is torque important in daily life?
A: Torque is crucial in tools, vehicle engines, bicycle pedals, door handles, and any rotating system.
