SUMMARY
Torque is minimized when the direction of a force is parallel to the radius vector, as established in the discussion. The mathematical definition of torque, represented as T = r x F (where x denotes the cross product), confirms that when the force is parallel to the radius vector, the torque becomes zero. This is illustrated with the example of a seesaw, where maximum torque occurs when the force is applied perpendicularly to the radius vector.
