In mechanical systems, what does torque measure?

Torque measures the rotational force applied to an object. This concept is critical in mechanical systems because torque is what causes an object to rotate around an axis. It is the product of the force applied at a distance from the pivot point or axis of rotation, and it quantifies how effectively a force can cause an angular acceleration of that object.

Understanding torque is essential in various applications, such as in engines and machinery, where efficient rotation is required. In practical terms, the greater the torque, the greater the ability to perform work in rotating an object. This distinct separation of torque from other concepts like linear force, speed, and energy helps clarify its unique role within mechanical engineering and physics. Linear force describes straightforward push or pull, while torque specifically aligns with how forces result in rotational movement.
