1. What is Torque?

Torque is a measure of the rotational force applied to an object. It's calculated as the product of force and the distance from the pivot point at which the force is applied.

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

• \( kg \) — Mass in kilograms
• \( g \) — Gravitational acceleration (9.80665 m/s²)
• \( Distance \) — Distance from pivot point in meters

Explanation: The calculator converts the mass (kg) to force (N) by multiplying by gravitational acceleration, then multiplies by the distance to get torque in Newton-meters (Nm).

3. Importance of Torque Calculation

Details: Torque calculations are essential in mechanical engineering, automotive applications, and any system involving rotational forces. Proper torque ensures safe and efficient operation of mechanical systems.

4. Using the Calculator

Tips: Enter mass in kilograms and distance in meters. Both values must be positive numbers. The calculator will automatically convert kg to N (using g=9.80665 m/s²) and then calculate the torque.

5. Frequently Asked Questions (FAQ)

Q1: Why do we multiply by gravitational acceleration?
A: To convert mass (kg) to force (N) using the relationship Force = mass × acceleration (Newton's second law).

Q2: What are common torque units?
A: The SI unit is Newton-meter (Nm). Other units include pound-feet (lb·ft) and kilogram-force meter (kgf·m).

Q3: How does distance affect torque?
A: Torque increases linearly with distance - applying the same force at a greater distance from the pivot creates more torque.

Q4: Is this calculation affected by Earth's gravity?
A: Yes, the standard calculation uses Earth's gravity (9.80665 m/s²). For other planets, you would need to adjust the gravitational constant.

Q5: Can this calculator be used for torque wrenches?
A: Yes, it can help determine the appropriate settings for torque wrenches when you know the mass and distance.
