In mechanics problems why always the force systems are replaced by force and couple systems. any practical example is available?

A force couple system is a pair of forces that act on an object in opposite directions, but not along the same line of action. This creates a rotational force, or torque, on the object.
Force couple systems do not cause an object to move in a linear direction, but rather cause it to rotate. The direction of rotation is determined by the direction of the forces and the distance between them.
Some common examples of force couple systems include opening a door by pushing on the handle, the steering mechanism of a car, and the movement of a lever or see-saw.
While a single force can cause an object to move in a linear direction, a force couple system causes rotational motion. Additionally, a single force has a single line of action, while a force couple system has two forces acting along different lines of action.
Force couple systems are commonly used to analyze the rotational motion of objects in mechanics problems. By understanding the direction and magnitude of the forces and the distance between them, the resulting torque can be calculated and used to determine the object's motion.
