Torque: The Twisting Force

This content introduces the concept of torque as the twisting or turning force that causes rotation, explaining its dependence on the applied force and the perpendicular distance from the axis of rotation. It delves into calculating torque by resolving forces into tangential and radial components, defines "line of action" and "moment arm," and establishes torque as a vector quantity with its direction determined by the right-hand rule.
