What is torque?

Question

What is torque?

Accepted Answer

Torque is a measure of rotational force that causes an object to rotate around an axis, crucial in mechanics and engineering.

Definition: Torque is defined as the product of force and the distance from the pivot point (lever arm), expressed as τ = r × F.
Units: Torque is measured in Newton-meters (Nm) in the SI system, indicating the amount of force applied at a distance.
Applications: Commonly used in automotive engineering, such as when tightening bolts or measuring engine performance.
Example: A wrench applying a force at a distance from a bolt creates torque, allowing the bolt to be tightened or loosened.
Right-Hand Rule: The direction of torque can be determined using the right-hand rule, where the thumb points in the direction of rotation.
