1. What is Torque?

Torque is a measure of the rotational force applied to an object. It represents how much force is causing an object to rotate around an axis and is measured in newton-meters (Nm) in the SI system.

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

• \( T \) — Torque (Nm)
• \( P \) — Power (W)
• \( \omega \) — Angular speed (rad/s)

Explanation: This formula calculates the torque generated when a certain amount of power is applied at a specific angular speed.

3. Importance of Torque Calculation

Details: Calculating torque is essential in mechanical engineering, automotive design, and industrial applications. It helps determine the rotational force needed for various machinery and equipment to function properly.

4. Using the Calculator

Tips: Enter power in watts (W) and angular speed in radians per second (rad/s). Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between torque and power?
A: Torque is a rotational force, while power is the rate at which work is done. Power equals torque multiplied by angular speed.

Q2: How do I convert RPM to rad/s?
A: Multiply RPM by 2π/60 (approximately 0.10472) to convert to rad/s.

Q3: Can I use horsepower instead of watts?
A: Yes, but you'll need to convert horsepower to watts first (1 hp = 745.7 W).

Q4: What are typical torque values for common applications?
A: Car engines typically produce 100-500 Nm, while electric motors vary from less than 1 Nm to thousands of Nm depending on size and application.

Q5: Why is torque important in vehicle performance?
A: Torque determines a vehicle's acceleration and pulling power, especially at lower speeds.
