1. What Is Torque Calculation?

Torque calculation using the formula T = P/ω determines the rotational force (in Newton-meters) produced by a system, where P is power in Watts and ω is angular velocity in radians per second. This is fundamental in mechanical engineering and physics applications.

2. How Does The Calculator Work?

The calculator uses the torque formula:

Where:

• \( T \) — Torque (Newton-meters, Nm)
• \( P \) — Power (Watts, W)
• \( \omega \) — Angular velocity (radians per second, rad/s)

Explanation: This formula calculates the rotational force generated when a certain power is applied at a specific angular velocity.

3. Importance Of Torque Calculation

Details: Accurate torque calculation is essential for designing mechanical systems, determining motor specifications, analyzing rotational dynamics, and ensuring proper functioning of various machinery and equipment.

4. Using The Calculator

Tips: Enter power in Watts, angular velocity in radians per second. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for this calculation?
A: Power must be in Watts (W) and angular velocity in radians per second (rad/s) to get torque in Newton-meters (Nm).

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 must first convert horsepower to Watts (1 hp = 745.7 W).

Q4: What is a typical torque value for electric motors?
A: This varies greatly by motor size and type, ranging from less than 1 Nm for small motors to hundreds of Nm for industrial motors.

Q5: Does this formula work for all rotational systems?
A: This formula provides theoretical torque based on power and angular velocity, but actual torque may vary due to efficiency losses and other factors in real-world systems.
