1. What Is Torque Calculation?

Torque calculation involves determining the rotational force produced by a system based on power input and angular velocity. It's essential for understanding mechanical systems and their performance characteristics.

2. How Does The Calculator Work?

The calculator uses the torque equation:

\[ \tau = \frac{P}{\omega}, \quad \omega = \frac{2\pi v}{r} \]

Where:

\( \tau \) — Torque (N·m)
\( P \) — Power (W)
\( \omega \) — Angular velocity (rad/s)
\( v \) — Linear speed (m/s)
\( r \) — Radius (m)
\( \pi \) — Mathematical constant (~3.14159)

Explanation: The equation converts linear speed to angular velocity, then calculates torque from power and angular velocity.

3. Importance Of Torque Calculation

Details: Accurate torque calculation is crucial for mechanical design, motor selection, power transmission systems, and ensuring proper operation of rotating machinery.

4. Using The Calculator

Tips: Enter power in watts, speed in meters per second, and radius in meters. All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between torque and power?
A: Torque and power are related through angular velocity: Power = Torque × Angular Velocity. Higher torque at the same speed means more power.

Q2: Why is angular velocity important in torque calculation?
A: Angular velocity converts rotational motion to a measurable quantity that relates directly to both linear speed and torque production.

Q3: What are typical torque values for different applications?
A: Torque values vary widely from small motors (fractional N·m) to industrial machinery (thousands of N·m), depending on the application and power requirements.

Q4: How does radius affect torque calculation?
A: Radius directly affects angular velocity - larger radius at the same linear speed results in lower angular velocity and higher torque for the same power.

Q5: Can this calculator be used for electrical motors?
A: Yes, this calculation applies to any rotating system where power input and rotational characteristics are known, including electrical motors.
