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 the force applied 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:

Where:

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

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

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial in mechanical engineering, physics, and various applications including automotive systems, machinery design, and structural analysis. It helps determine the rotational effect of forces and is essential for designing efficient mechanical systems.

4. Using the Calculator

Tips: Enter force in Newtons (N), distance in meters (m), and angle in degrees. All values must be valid (force > 0, distance > 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 lever length affect torque?
A: Longer levers produce greater torque for the same applied force, which is why longer wrenches make it easier to loosen tight bolts.

Q5: Can torque be negative?
A: Yes, torque can be negative indicating rotation in the opposite direction, but the calculator provides the magnitude only.
