1. What is Net Torque?

Net torque is the sum of all torques acting on an object. It determines the rotational motion of the object, causing it to rotate with angular acceleration if the net torque is nonzero.

2. How Does the Calculator Work?

The calculator uses the net torque formula:

Where:

• \( T_{net} \) — Net torque (Nm)
• \( T_i \) — Individual torque values (Nm)

Explanation: The calculator sums all torque values entered, taking into account their direction (positive or negative values).

3. Importance of Net Torque Calculation

Details: Calculating net torque is essential in physics and engineering for analyzing rotational systems, designing mechanical components, and understanding rotational equilibrium.

4. Using the Calculator

Tips: Enter torque values separated by commas. Use positive values for counterclockwise torques and negative values for clockwise torques (or vice versa depending on your coordinate system).

5. Frequently Asked Questions (FAQ)

Q1: What is the unit of torque?
A: Torque is measured in Newton-meters (Nm) in the SI system.

Q2: How do I represent direction in torque values?
A: Use positive values for one direction (e.g., counterclockwise) and negative values for the opposite direction (e.g., clockwise).

Q3: What does a net torque of zero mean?
A: A net torque of zero means the object is in rotational equilibrium - it's either not rotating or rotating at a constant angular velocity.

Q4: Can I use different units for torque?
A: While Nm is standard, you can use other units like foot-pounds, but be consistent with all values and note that the result will be in the same units.

Q5: How is torque different from force?
A: Torque is a rotational analog of force. While force causes linear acceleration, torque causes angular acceleration.
