1. What is Torque?

Torque is a measure of the rotational force applied to an object. In automotive terms, it represents the twisting force that the engine generates, which is crucial for acceleration and towing capacity.

2. How Does the Calculator Work?

The calculator uses the basic torque equation:

Where:

• \( Force \) — Applied force in Newtons (N)
• \( Distance \) — Distance from the pivot point in meters (m)

Explanation: The equation calculates the rotational force based on how much force is applied and how far from the rotation point it's applied.

3. Importance of Torque Calculation

Details: Torque is a critical specification for vehicle performance. Higher torque generally means better acceleration and towing capacity. It's particularly important for trucks and performance vehicles.

4. Using the Calculator

Tips: Enter force in Newtons and distance in meters. For engine torque, this would typically be the force exerted by the pistons and the crank radius.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between torque and horsepower?
A: Torque measures rotational force, while horsepower measures work done over time (power). Horsepower = (Torque × RPM) / 5252.

Q2: What are typical torque values for cars?
A: Economy cars: 100-150 N·m, Performance cars: 300-700 N·m, Trucks: 400-1000+ N·m.

Q3: Why is torque important for towing?
A: Higher torque allows vehicles to overcome heavier loads and maintain speed on inclines.

Q4: How is engine torque measured?
A: Using a dynamometer which measures the rotational force at the engine's crankshaft.

Q5: Does electric motors have different torque characteristics?
A: Yes, electric motors typically deliver maximum torque at 0 RPM, providing instant acceleration.
