1. What is Torque?

Torque is a measure of the force that can cause an object to rotate about an axis. It is a vector quantity, meaning it has both magnitude and direction. Torque is calculated as the product of force and the perpendicular distance from the axis of rotation to the line of action of the force.

2. How Does the Calculator Work?

The calculator uses the torque equation:

\[ T = F \times r \times \sin(\theta) \]

Where:

\( T \) — Torque (Nm)
\( F \) — Force applied (N)
\( r \) — Distance from axis (m)
\( \theta \) — Angle between force vector and lever arm (degrees)

Explanation: The equation calculates the rotational force applied at a certain distance from the pivot point, taking into account the angle of application.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial in mechanical engineering, automotive design, construction, and many other fields where rotational forces need to be measured and controlled.

4. Using the Calculator

Tips: Enter force in newtons (N), radius in meters (m), and angle in degrees. All values must be valid (force > 0, radius > 0, angle between 0-180 degrees).

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: Why is the angle important in torque calculation?
A: The angle determines how much of the force contributes to rotation. Maximum torque occurs when the force is applied perpendicular to the lever arm (θ = 90°).

Q3: What are common units for torque?
A: Newton-meters (Nm) in the SI system, and foot-pounds (ft-lb) or inch-pounds (in-lb) in the imperial system.

Q4: How does torque relate to power?
A: Power is the rate of doing work, while torque is a measure of rotational force. In engines, power = torque × angular velocity.

Q5: When is torque zero in this calculation?
A: Torque is zero when either force is zero, radius is zero, or when the angle is 0° or 180° (force applied directly toward or away from the pivot point).
