# Torque

Torque, a fundamental concept in physics and engineering, represents the rotational force acting on an object around an axis. It plays a pivotal role in various mechanical systems, ranging from engines to simple machines. Defined as the product of force and the distance from the axis of rotation, torque determines an object's ability to rotate and is crucial for understanding rotational motion and equilibrium. Whether in the context of automotive engineering, robotics, or biomechanics, a comprehensive understanding of torque is indispensable for analyzing and designing systems that involve rotational motion.
