1. What Is Resultant Torque?

Resultant torque (T_net) is the vector sum of all individual torques acting on an object. It determines the net rotational effect and whether an object will rotate, and if so, in which direction.

2. How Does The Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The calculator sums all torque values, considering both magnitude and direction (positive values typically indicate counterclockwise rotation, negative values clockwise).

3. Importance Of Torque Calculation

Details: Calculating resultant torque is essential in mechanical engineering, physics, and various applications involving rotational motion, from simple levers to complex machinery.

4. Using The Calculator

Tips: Enter torque values separated by commas. Use positive values for counterclockwise torques and negative values for clockwise torques. All values should be in Newton-meters (Nm).

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between torque and force?
A: Force causes linear acceleration, while torque causes rotational acceleration. Torque depends on both the magnitude of force and the distance from the pivot point.

Q2: How do I determine the direction of torque?
A: Use the right-hand rule: point fingers in direction of rotation, thumb indicates torque vector direction. Conventionally, counterclockwise is positive.

Q3: What if torques are applied at different angles?
A: For torques not perpendicular to the lever arm, use T = r × F × sin(θ), where θ is the angle between force vector and lever arm.

Q4: When is the resultant torque zero?
A: When the sum of all clockwise torques equals the sum of all counterclockwise torques, creating rotational equilibrium.

Q5: What are common units for torque?
A: Newton-meters (Nm) in SI units, pound-feet (lb-ft) in imperial units, and dyne-centimeters in the CGS system.
