SUMMARY
The line of action of a force is defined as an infinite line that extends in both directions through the point of application of the force, representing the direction of the force vector. When the line of action differs from the axis of rotation, torque is generated. For example, if a force is applied to kick a ball eastward, the line of action aligns with the ball's movement. Understanding this concept is crucial for analyzing rotational dynamics and torque applications.
