1. What is the Torque Formula?

The torque formula T = P/ω calculates torque from power and angular velocity. Torque represents the rotational force produced by a system, while power is the rate at which work is done, and angular velocity is the rotational speed.

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

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

Explanation: This formula shows the direct relationship between power and torque, with torque being inversely proportional to angular velocity when power is constant.

3. Importance of Torque Calculation

Details: Torque calculation is essential in mechanical engineering, automotive design, and industrial applications for determining the rotational force required or produced by machinery and engines.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What are the units used in this calculation?
A: Torque is measured in Newton-meters (Nm), power in watts (W), and angular velocity in radians per second (rad/s).

Q2: Can I use different units for this calculation?
A: Yes, but you must ensure unit consistency. For example, if power is in horsepower, it must be converted to watts (1 hp = 745.7 W).

Q3: What is the relationship between torque and power?
A: Power is the product of torque and angular velocity (P = T × ω). For a given power, torque decreases as rotational speed increases.

Q4: Where is this calculation commonly used?
A: This calculation is widely used in automotive engineering, electric motor design, mechanical systems, and any application involving rotational motion.

Q5: What if I have RPM instead of rad/s?
A: Convert RPM to rad/s using the formula: ω (rad/s) = RPM × 2π / 60
