1. What is the Torque Formula?

The torque formula calculates rotational force from horsepower and RPM. It provides a fundamental relationship between power, rotational speed, and torque in mechanical systems.

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

• \( Torque \) — Rotational force (lb-ft)
• \( HP \) — Horsepower
• \( RPM \) — Revolutions per minute
• \( 5252 \) — Conversion constant

Explanation: The formula demonstrates the inverse relationship between torque and RPM for a given horsepower output.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial for engine performance analysis, mechanical design, power transmission systems, and vehicle dynamics.

4. Using the Calculator

Tips: Enter horsepower and RPM values. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why is 5252 used in the formula?
A: 5252 is the conversion constant that results from the relationship between horsepower, torque, and RPM in the imperial measurement system.

Q2: What are typical torque values for engines?
A: Torque values vary widely by engine type and size. Automotive engines typically range from 100-500 lb-ft, while industrial engines can produce much higher torque.

Q3: How does torque relate to vehicle performance?
A: Torque determines a vehicle's acceleration and pulling power, while horsepower relates to top speed and overall performance capability.

Q4: Can this formula be used for electric motors?
A: Yes, the formula applies to any rotating mechanical system, including electric motors, though specific motor characteristics may affect actual performance.

Q5: What's the difference between torque and horsepower?
A: Torque is a measure of rotational force, while horsepower is a measure of work done over time. Horsepower = (Torque × RPM) / 5252.
