What is resultant torque?

Resultant torque is the overall rotational effect produced by a combination of multiple torques acting on an object. It is calculated by vectorially adding all individual torques, taking into account their magnitudes and directions. The resultant torque determines the object's angular acceleration according to Newton's second law for rotation, which states that torque equals the moment of inertia multiplied by angular acceleration. A non-zero resultant torque indicates that the object will undergo angular motion or change its rotational state.
